2.3.7 Gas cylinder installation

The welder has a platform on the rear of the unit to support a gas cylinder (see fig. 2-7). If you plan

to move the welder around the shop, use only small cylinders for transport safety (outside diameter = 140

mm, height ≤ 500 mm, weight ≤ 10 Kg, service pressure ≤ 20 Mpa). Larger cylinders (outside diameter >

140 mm, or height > 500 mm, or weight > 10 Kg, service pressure ≤ 20 Mpa) should be secured in a

permanent location or to a separate cart, not to the welder. Secure the small cylinder with the straps

supplied with the welder. Small cylinders can be easily secured in place using the top rack “A”.

2.3.8 Connecting welder to a gas cylinder.

Clean the threads of the gas cylinder valve. Open the gas valve for a few seconds to blow out any

dirt or particles that may have entered the orifice, in order to prevent them from entering the regulator.

Check the regulator (outlet flow meter: 0-25L/Min., inlet gauge: 0-25 Mpa, pressure range for safe

outflow: 0-0.35 Mpa) to make sure that it was supplied with a gasket. Tighten the regulator coupling

to the cylinder gas valve. Now connect the welder gas line to the hose barb outlet on your regulator.

A stainless steel hose clamp can be used to ensure a leak-proof connection (see fig. 2-8).

Check all connections for leaks by opening the regulator and cylinder gas valves.

Always shut off the regulator and cylinder gas valves when the unit is not in use.

3.2 Operation process

3.2.1 Using cored wire.

The welder can be used with special 0.8 flux wire that does not require protective gas. This wire, contrary

to electrodes, does not leave slag and gives better bead penetration with substantially lower line absorption.

Make sure you use the proper welding polarity (as shown in fig. 3-2B).

The grounding cable connects with the " + " (positive) terminal, and the welding torch cable connects

with the " – " (negative) terminal.

connects with the " – " (negative) terminal, and the welding torch cable connects with the " + "

(positive) terminal. The diameter of the wire you select should correspond to the thickness of the work

piece. Make sure that the contact tip you are using is the same size as the wire diameter.

Step 1: Use the ground clamp to connect the grounding cable and work piece, or connect to the metal

carriages (as on work table). Make sure the clamp is in full contact with the work piece, and the

surface is free of rust and paint.

Step 2: Select the welding current and adjust the positions of the MIN/MAX and 1/2 switches (use higher

welding current for thicker material).

Step 3: Check the position of the power switch (position must be OFF), then insert the inlet wire to

the socket (MIG 136 voltage is 120VAC, MIG 156 voltage is 230VAC, rated current of

socket ≥ 20A).

Step 4: Discharge the nozzle cover and contact tip at the head of welding torch, pull the

soft pipe.

Step 5: Make sure that the welding tongs that clamp the rod are not in contact with any grounding objects.

Turn the ON/OFF switch to the ON position – the power lamp

will light (green).

Step 6: Press and hold the torch button until the distance between the wire and welding

torch is 30 mm, then release button.

Step 7: Turn off the power. Fix the contact tip and nozzle cover onto the welding torch

(wire must go through the contact tip and nozzle cover).

Step 8: Open the gas valve on the regulator and set a flow of 5-7 L/Min., depending on the welding

position chosen.

Step 9: Turn on the power and press the switch a few times. Adjust the speed by

turning the wire feed speed knob, in relation to the position of the welding current selector.

Step 10: Orient yourself on the area to be welded, and place the face shield over your eyes.

Step 11: Press and hold the torch button as you stroke the area to be welded. The electrode wire

will ignite the arc.

Step 12: Once the arc is ignited, tilt the electrode wire forward at an angle of approximately 35°

(see fig. 3-3).

Step 13: When the weld is complete, lift the electrode wire clearly away from any grounded object. Set

your face shield down and turn the power switch to OFF.

Step 14: Unplug the Power Cord from the electrical outlet.

Step 15: Close the gas cylinder valve.

Step 16: Depress torch trigger to release gas in regulator (the gas pressure regulator will return to 0).

If welding with large current for extended periods, or if you exceed the duty

cycle, the overload lamp will light (yellow) and the machine will stop working

until the unit cools. When the overload lamp lights up you must stop welding

and wait about 15 minutes before continuing.
