3.2 „ + ” Marking on the welding current socket

The „ + “ sign indicates the positive pole of the welding power source. The earth cable is

connected to this socket when TIG welding.

3.3 „ – “ Marking on the welding current socket

The „ - “ sign indicates the negative pole of the welding power source. The torch is

connected to this socket when TIG welding.

4 Mains power supply

The welding unit must be fitted with the correct mains supply plug which fully complies with

the International electrical standards and the local electrical regulations. The unit must only

be operated with fuses or circuit breakers with a maximum current rating of 16A. When the

mains power is switched on, the mains ON/OFF switch on the back of the unit is illuminates.

If the TIGER 170 is switched ON and OFF frequently (in quick succession), the unit may

automatically switch over to the power supply protection mode. In this mode, the unit cannot

be re-started and the green indicator lamp flashes. If this occurs, switch the unit OFF and

wait for approx. 2 minutes. The unit can then be restarted.

5 Installation

Care should be taken during installation of the unit to ensure that the ventilation slots are not

covered and the area where the machine is to be used affords a protection classification of

IP23.

6 Description of Welding processes

6.1 TIG Welding

6.1.1 Principle of the TIG welding process

The unit supplies a current up to 170 A DC for the TIGER 170 and 210 A for the TIGER 210

for TIG welding. The mains current limiting function is inactive during the TIG welding mode.

Despite the higher output current, the power drawn from the mains supply is lower than

required for stick electrode welding; the mains fuse is therefore unlikely to trip-out during TIG

welding.

During TIG welding, a welding arc is established between a tungsten electrode and the

workpiece. The shielding gas normally used is an inert gas such as pure Argon, Helium or a

mixture of both.

The negative pole of the power supply is connected to the tungsten electrode, the positive

pole is connected to the workpiece. The tungsten electrode is the conductor and the current

carrier (non-consumable electrode). The filler metal required is fed manually in the form of a

rod or by a separate cold wire feed unit. The tungsten electrode, and the welding pool is

protected from the atmosphere by the inert shielding gas supplied from the gas nozzle.

7

6.1.2 Arc ignition with INTIG Energy

The highly intelligent processor ensures that the ideal ignition energy is automatically chosen

depending upon the actual weld current setting, this applies not only for HF, but also for the

Lift-Arc ignition sequence.

When the selector switch  is set to position ´"HF On", the high-frequency ignition unit is

ready for operation. To ignite the arc, the electrode must be held about 3 to 5 mm above the

workpiece. When the torch button is pressed, the shielding gas is pre-ionised by a high-

voltage, the current flows between the end of the electrode and the workpiece so that the

main arc is established. The ignition of the arc without contact between the tungsten

electrode prevents tungsten inclusion in the weld. once the arc has successfully been ignited

the high-frequency ignition unit is switched off automatically during welding.

When the selector switch  is set to position "HF Off", contact ignition can also be carried

out using the processor control ignition system (Lift Arc) to strike the arc. In order to ignite the

welding arc, the tip of the electrode must be placed on the workpiece and the torch button

depressed. The processor control system reduces the ignition current so that the tip of the

electrode does not heat up. The electrode is then gradually lifted away from the workpiece,

this action ignites the arc under the system processor control, this results in arc ignition

without HF and also minimum wear on the tungsten electrode. This process is essential

when welding in areas where sensitive electronic equipment is in operation (e.g. repair welds

on CNC-controlled machines) and where there may be a risk of damage caused by high-

voltage.

When the selector switch  is set to position "Electrode“, the HF ignition system is

automatically disabled.

The electrode diameter depends on the welding current. A diameter of 1.6 mm is

recommended for welding currents up to 70 A and 2.4 mm for higher currents.

6.1.3 The Non-latch torch button operation mode sequence

Step 1: Activate torch button

° The solenoid valve for the shielding gas is energised

° The arc ignition cycle starts after the fixed gas pre-flow time (0.1 sec.) has elapsed

° The set welding current is automatically reached after the up-slope time (0.1 sec)

has elapsed.

Step 2: Release torch button

° The current falls to 20% of the set welding current after the down-slope time has

elapsed, the arc is then automatically switched off.

° The shielding gas continues to flow for the duration of set gas post-flow time.

Non-latched welding mode is recommended for rapid, controlled tacking and manual spot

welding.

6.1.4 The Latched torch button operation mode sequence

Step 1: Activate the torch button

° The solenoid valve for the shielding gas is energised

° The arc ignition cycle starts after the fixed gas pre-flow time (0.1 sec.) has elapsed

° The welding current rises to 50% of the value set on the main current potentiometer

8

GB

Step 2: Release torch button

° The set welding current is automatically reached after the up-slope time (0.1 sec)

has elapsed.

Step 3: Activate the torch button once again

° The welding current falls to 20% of the welding current set on the main current

potentiometer for the duration of the downslope time

° The welding current remains at this 20% level.

Step 4: Release torch button

° The arc is extinguished

° The shielding gas continues to flow for the duration of the gas post-flow time.

In the latched torch button operation mode, the operator does not need to keep the torch

button pressed, allowing welding for a relatively long period of time without fatigue.

6.1.5 Gas post-flow timer (0.5 s – 25.0 s)

The gas post-flow time  is the time which elapses after the arc is extinguished and before

the shielding gas solenoid valve is de-energised. The shielding gas protects both the

workpiece and the tungsten electrode from contamination form the surrounding atmosphere

until they have cooled down sufficiently.

6.1.6 Downslope timer Crater fill (0.0 s – 10.0 s)

The downslope timer  is the time during which the welding current decays to the crater fill

current. In the Non-latched operation mode, the downslope time begins as soon as torch

button 1 is released. In the Latched operation mode, the downslope time commences when

torch button 1 is activated during welding. The longer the setting of the downslope time, the

lower the risk of creating end crater cracking.

6.1.7 Manual Pulsing function

If the torch button is activated during the downslope when in the non-latched TIG 2 mode,

the welding current immediately rises to the value set on the main current setting

potentiometer. The length of each pulse and is manually controlled by the operator

depending upon when he activates the torch button, as a result the average heat input will be

reduced.

6.2 Stick Electrode (MMA) welding

6.2.1 Stick Electrode welding in the Fuse Hold mode

In this mode of operation, the actual current drawn from the mains is continuously monitored.

If necessary, the welding current is reduced to the level required to prevent the mains fuse

form tripping out. A quick acting miniature circuit breaker similar to the type normally installed

in households should be installed in the mains supply cabinet as the Fuse Hold function is

designed for use in conjunction with this type of circuit breaker.

The machine is designed for use with all the common types of stick electrodes. The

maximum current is 140 A for the TIGER 170 and 160 A for the TIGER 210. If a higher

current is set, the current is automatically limited to 140 A / 160 A.

This current is usually sufficient to weld most common types of stick electrodes of up to

3.25mm diameter.

9

For the precise selection of the electrode polarity and current settings for individual

electrodes, please refer to the electrode manufacturer's instructions.

If for some reason there is a permanent short circuit between the electrode and the

workpiece, the Anti-Stick Function will automatically operate after approx. 1.3s, this then

limits the output current to approx. 35 A.

6.2.2 Stick Electrode welding with the BOOSTER Mode

In this mode of operation, the mains fuse monitoring function is automatically de-activated.

The maximum possible welding current is then 150 A for the TIGER 170 and 170 A for the

TIGER 210. If a higher current is selected, the welding current output is automatically limited

to 150 A /170 A.

6.2.3 Anti-Stick Function

If there is a permanent short circuit between the electrode and the workpiece during welding,

the Anti-Stick Function is automatically activated after approx. 1.3s. This function

automatically limits the welding current to approx. 35 A. This prevents the electrode from

overheating and burning out. The operator terminates the short circuit simply by removing

the contact between the electrode and the workpiece.

6.2.4 INTIG Energy for electrode welding

The INTIG energy (Intelligent Ignition Energy) automatically pre-sets a high power ignition

current sequence, which ensures reliable and smooth ignition when stick electrode welding.

Electrode sticking is prevented during re-ignition even with basic electrodes as the high

power ignition current pulse is only activated as the electrode is lifted off following contact

between the electrode and the workpiece, (similar to the Lift-Arc function for TIG welding).

7. Remote control units

7.1 TIG PLUS 1 foot-operated remote current control unit

(Article No. 753 1001)

The TIG PLUS 1 remote control unit is equipped with a foot-pedal for the infinitely varying the

output current during welding. When the pedal is fully depressed, the welding current

reaches the full value pre-set on the machine. The machine can therefore be set to the

maximum current required, allowing optimum resolution over the required operating current

range.

The TIG PLUS 1 remote control unit also incorporates a rocker switch which has the

following function:

- Hand control signal

The welding current is switched on and off using the torch button; the non-latch and latched

functions as well as the downslope time are active and can be selected on the machine. The

foot pedal controls the welding current, it is not de-activated! This type of operation is

intended for mass production applications where the welding current usually remains

constant and only needs to be reduced slightly from time to time. The current ramping

functions which are active in this mode of operation are therefore beneficial.

10

GB

- Foot control signal

In this mode of operation the welding current is switched on and off using the pedal and is

controlled by the operator using his foot. The welding machine automatically operates in the

non-latch mode only. The upslope and downslope times are automatically set to their

minimum values.

Warning: Ensure that accidental operation of the machine is prevented by accidentally

depressing the foot switch. When the foot pedal is activated, there is a danger of electric

shock caused by the high voltage pulses generated by the welding set!

7.2 TIG PLUS 2 hand-operated remote control unit (order no. 753 1002)

The TIG PLUS 2 hand-operated remote control unit allows the welding current to be adjusted

not only before but also during the welding operation. When the hand regulator is set to

100%, the welding current reaches the full value set on the welding output potentiometer on

the machine. The machine can therefore be set to the maximum current required, allowing

optimum resolution in the required current range. The welding current is switched on and off

using the torch button; the Non-latch and latched operating modes as well as the downslope

time are active and can be selected on the machine.

7.3 REHM SR17/4m torch with current control potentiometer and leather

outer cover (Article No. 763 1711)

The REHM R-SR17/4m TIG torch with current control potentiometer and leather outer cover

offers the same functionality as the hand-operated remote control unit described in Section

7.2 above. The welding current can be set and adjusted, prior to and during welding using

the adjustment potentiometer which is integrated within the torch handle. The torch is

connected to the standard torch control and remote control sockets of the TIGER 170/210.

The REHM R-SR17/4m TIG torch with current control potentiometer and leather outer cover

is specifically designed for use with the electronic control of the TIGER 170/210.

WARNING: The use of any other TIG torches with remote control functions except those

specifically supplied by REHM on the TIGER 170 will void the manufacturers warranty.

7.4 TIGER 170 SET (Article No. 150 3171)

TIGER 170 complete in a metal carrying case, together with the REHM R-SR 17/8m torch

with leather outer sleeve and integrated current setting potentiometer. Pressure regulator,

and Workpiece return cable 4m long. The carrying case is of a robust design and affords

protection for the welding machine and accessories. The case is fitted with high quality

catches which can be locked. The unit has very modest dimensions (Lx B x H: 565 x 360 x

200 mm) and weighs a mere 18 kg, making it the ideal companion for the arduous life in the

workshop as well as the building site.

8. Limitations of Application

The units can be used in any environmental conditions which afford protection corresponding

to Protection Classification IP23 or less. For welding in certain locations (e.g. stables), the

Protection Classification of the welding units has to meet special requirements. The use of

11

machines in such an environments should be carefully examined on a case by case basis.

The units are not designed for multi-shift operation.

9. Maintenance

The units do not require regular maintenance However the condition of the electrical cables

and plugs must be checked before using the machine.

9.1 Proper waste disposal

Only for EU countries.

Do not dispose of electric tools together with household waste material.

In observance of European Directive 2002/96/EC on waste electrical and

electronic equipment and its implementation in accordance with national

law, electric tools that have reached the end of their life must be collected

separately and returned to an environmentally compatible recycling facility.

Témoin de température. La diode luminescente (jaune) s’allume lorsque la

température maximale autorisée du poste est dépassée. Tant que cette diode

est allumée, le courant de sortie est coupé. Après refroidissement du poste, la

diode s’éteint et le soudage peut être repris automatiquement. Quand le témoin

clignote, la surveillance interne est déclenchée. Le poste est remis en service

en coupant puis rétablissant le courant au commutateur principal. Merci d’en

informer le Service Clientèle REHM (RKS).

3.3 Marquage « - » / symbole TIG sur la douille de courant de soudage

Le signe « - » indique le pôle négatif de la source de courant de soudage. Dans le soudage

TIG, la torche est connectée à cette douille.

4 Branchement au secteur

Le poste de soudage est muni d’une fiche de prise de courant de sécurité. Le poste

fonctionne sous un courant nominal de 16 A avec des coupe-circuit ou des disjoncteurs de

protection de canalisations. Le mode de service EIN (MARCHE) est indiqué par l’allumage

du commutateur principal placé au dos.

Lors de fréquentes (brèves et successives) activations et désactivations du TIGER, il peut

arriver que le poste commute en mode protection, dans lequel il ne peut s’amorcer et la

lampe témoin de marche verte s’allume et s’éteint. Dans ce cas, mettre le poste hors service

et attendre 2 minutes environ. Le poste peut alors être remis en service.

5 Installation

Lors de l’installation des postes, veiller à ce que les grilles d’aération ne soient pas

recouvertes et à ce que l’environnement soit conforme à la classe de protection IP23.

6 Modes de soudage

6.1 Soudage TIG

6.1.1 Principe du procédé de soudage TIG

Pour le soudage TIG, le poste met à disposition un courant pouvant atteindre 170 A / 210 A.

Dans cette fonction, la limitation du courant du secteur n’est pas activée. Étant donné que,

malgré un courant plus important, la puissance utile en mode TIG est inférieure à celle du

soudage avec électrodes, il ne faut pas s’attendre ici à un déclenchement de coupe-circuit.

Dans le procédé de soudage TIG, l’arc électrique se forme librement entre une électrode en

tungstène et la pièce d’œuvre. Le gaz protecteur est un gaz rare tel que l’argon, l’hélium ou

un mélange de ces deux gaz.

Le pôle négatif de la source d’énergie est sur l’électrode en tungstène, le pôle positif sur la

pièce d’œuvre. L’électrode conduit le courant et porte l’arc électrique (électrode

permanente). Le métal d’apport est appliquée sous forme de baguette tenue à la main ou

sous forme de fil par un appareil d’alimentation en fil froid séparé. L’électrode en tungstène

et le bain de fusion ainsi que l’extrémité en fusion du métal d’apport sont protégés de l’entrée

de l’oxygène de l’air par le gaz inerte protecteur qui s’échappe des buses disposées de

manière concentrique autour de l’électrode.

6.1.2 L’amorçage de l’arc électrique avec INTIG-Energy

Avec le mode INTIG-Energy (Intelligent Ignition Energy), le TIGER 170 / 210 maîtrise la

forme intelligente de commande d’énergie d’amorçage. La commande à processeur règle de
