3.3 Operation
Step 1: Use ground clamp to connect the grounding cable and work piece or connect the metal carriages (as
work table) make sure the clamp has been contacted fully with work piece and clear any rust and paint.
Step 2: Check the position of power switch, position must be on “OFF”, then insert the inlet wire to the socket
(voltage is 230VAC, rated current of socket ≥15A).
Step 3: Discharge the nozzle cover and contact tip at the head of welding torch, pull the soft pipe.
Step 4: The welding tongs that clamp the rod can’t be contacted with any grounding objects. Turn the
conversion switch to voltage position (the same with input voltage) and the power lamp (green) will light.
Step 5: Press (and hold) the torch button until distance between wire and welding torch is 30mm, loosen torch
button.
Step 6: Close the power; fix the contact tip and nozzle cover onto the welding torch. (Wire must run through the
contact tip and nozzle cover.)
Step 7: Open the power, press the switch repeatedly, adjust the speed by turning the adjusting wire feed speed
knob.
Step 8: Orient yourself on the area to be welded, and then place the face shield over your eyes.
Step 9: Press (and hold) the torch button and stroke the area to be welded with the electrode wire
to ignite the arc.
Step 10: Once the arc is ignited, tilt the electrode wire forward at an angle of approximately 35
