Safety Precautions

SECTION 1:

SAFETY PRECAUTIONS

WARNING

SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not properly

installed, used, and maintained. Misuse of this equipment and other unsafe practices

can be hazardous. The operator, supervisor, and helper must read and understand the

following safety warnings and instructions before installing or using any welding or cutting

equipment, and be aware of the dangers of the welding or cutting process. Training

and proper supervision are important for a safe work place. Keep these instructions for

future use. Additional recommended safety and operating information is referenced in

each section.

ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH

Install and maintain equipment in accordance with the National Electrical Code (NFPA

70) and local codes. Do not service or repair equipment with power on. Do not operate

equipment with protective insulators or covers removed. Service or repair to equipment

must be done by qualiﬁ ed and/or trained personnel only.

Do not contact electrically live parts. Always wear dry welding gloves that are in good condition.

Aluminized, protective clothing can become part of the electrical path. Keep oxygen cylinders, chains,

wires, ropes, cranes, and hoists away from any part of the electrical path. All ground connections must

be checked periodically to determine if they are mechanically strong, and electrically adequate for the

required current. When engaged in AC welding/cutting under wet conditions or where perspiration is a

factor, the use of automatic controls for reducing the no load voltage is recommended to reduce shock

hazards. Accidental contact must be prevented when using open circuit voltage exceeding 80 volts AC,

or 100 volts DC by adequate insulation or other means. When welding is to be suspended for any length

of time, such as during lunch or overnight, all electrode holders and electrodes should be removed from

the electrode holder and the power supply should be turned OFF to prevent accidental contact. Keep

MIG-Guns, electrode holders, TIG torches, Plasma torches, and electrodes away from moisture and

water. See safety and operating references 1, 2, and 8.

SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH

Ventilation must be adequate to remove smoke, fumes, and gases during operation to

protect operators and others in the area. Vapors of chlorinated solvents can form the

toxic gas “Phosgene” when exposed to ultraviolet radiation from an electric arc. All

solvents, degreasers, and potential sources of these vapors must be removed from the

operating area. Use air-supplied respirators if ventilation is not adequate to remove all

fumes and gases. Oxygen supports, and vigorously accelerates ﬁ re and should never be used for

ventilation. See safety and operating references 1, 2, 3, and 4.

1-2

SET-UP AND SAFE OPERATING PROCEDURES

89210002Safety Precautions

ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE EYES AND BURN SKIN

Welding and cutting processes produce extreme localized heat and strong ultraviolet

rays. Never attempt to weld/cut without a federally compliant welding helmet with the

proper lens. A number 12 to 14 shade ﬁ lter lens provides the best protection against

arc radiation. When in a conﬁ ned area, prevent the reﬂ ected arc rays from entering

around the helmet. Approved shielding curtains and appropriate goggles should be used

to provide protection to others in the surrounding area. Skin should be protected from arc rays, heat,

and molten metal. Always wear protective gloves and clothing. All pockets should be closed and cuffs

sewn shut. Leather aprons, sleeves, leggings, etc. should be worn for out-of-position welding and cutting,

or for heavy operations using large electrodes. Hightop work shoes provide adequate protection from

foot burns. For added protection, use leather spats. Flammable hair preparations should not be used

when welding/cutting. Wear ear plugs to protect ears from sparks. Where work permits, the operator

should be enclosed in an individual booth painted with a low reﬂ ective material such as zinc oxide. See

safety and operating references 1, 2, and 3.

WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS

Combustibles reached by the arc, ﬂ ame, ﬂ ying sparks, hot slag, and heated materials

can cause ﬁ re and explosions. Remove combustibles from the work area and/or provide

a ﬁ re watch. Avoid oily or greasy clothing as a spark may ignite them. Have a ﬁ re

extinguisher nearby, and know how to use it. If welding/cutting is to be done on a metal

wall, partition, ceiling, or roof, precautions must be taken to prevent ignition of nearby

combustibles on the other side. Do not weld/cut containers that have held combustibles.

All hollow spaces, cavities, and containers should be vented prior to welding/cutting to permit the escape

of air or gases. Purging with inert gas is recommended. Never use oxygen in a welding torch. Use only

inert gases or inert gas mixes as required by the process. Use of combustible compressed gases can

cause explosions resulting in personal injury or death. Arcing against any compressed gas cylinder can

cause cylinder damage or explosion. See safety and operating references 1, 2, 5, 7, and 8.

NOISE CAN DAMAGE HEARING

Noise from the air carbon-arc process can damage your hearing. Wear protective hearing

devices to ensure protection when noise levels exceed OHSA standards. Adequate hearing

protection devices must be worn by operators and surrounding personnel to ensure personal

protection against noise. See safety and operating references 1, 2, and 6.

WARNING

This product contains chemicals, including lead, or otherwise produces chemicals

known to the State of California to cause cancer, birth defects and other reproductive

harm. Wash hands after handling.

3.04 WIRE FEED SPEED CALIBRATION

NOTE

The Thermal Arc 252i machine must be calibrated to the spool gun before operating to

ensure optimum welding characteristics.

Wire Feed Speed Calibration

Procedure

WARNING

DO NOT TOUCH the electrode wire

while it is being fed through the

system. The electrode wire will be

at welding voltage potential.

Required Equipment/Tools:

• Appropriate personal protective gear:

gloves, safety glasses, etc.

• Tape measure

• Spool of desired ﬁ ller metal

• Spool Gun

• T15 (Torx) driver (supplied)

NOTE

To perform the wire feed speed

calibration procedure the end of

the Spool wire needs to be trimmed

back to the contact tip of the Spool

Gun before and after feeding wire

out for measurement.

NOTE

This calibration procedure does

not affect the calibration of the

wirefeeder inside the 252i. To re-

calibrate the wirefeeder inside the

252i all remote devices must be

disconnected from it.

Installation and Operation

SET-UP AND SAFE OPERATING PROCEDURES

5. Temporarily place the board back in

the unit. The DIP switch will need to be

returned to the “OFF” position when the

calibration process is complete.

6. Re-connect the input power to the

welding power supply and turn it ON. The

left and right displays should show “ERR

30” which means the normal welding

output has been prevented.

NOTE

From this point forward unless

noted all adjustments will be made

using the controls on the Thermal

Arc 252i.

NOTE

The power supply requires two

values to properly calibrate wire

feed speed. A low feed speed

value and a high feed speed value.

Default speeds span the most

typical jobs. You may choose

alternates that better represent

your work. The closer an upper

or lower speed is to an actual

procedure, the better the accuracy.

NOTE

To perform the wire feed speed

calibration procedure the end of

the Spool wire needs to be trimmed

back to the contact tip of the Spool

Gun before and after feeding wire

out for measurement.

10. Using the right knob on the 252i, adjust

wire feed speed value in the right
