Chapter 3 Operation
Step8: Open the power, press the switch spasmodically, adjust the speed by turning the adjusting
wire feed speed knob, in relation to the position of the welding current selector.
Step9: Orient yourself on the area to be welded, and then place the Face Shield over your eyes.
Step10: Press (and hold) the torch button and stroke the area to be welded with the electrode wire
to ignite the arc.
Step11: Once the arc is ignited, tilt the electrode wire forward at an angle of approximately 35
o
.
(as diagram 3-3)

Step12: When the weld is complete, lift the electrode wire clearly away form any grounded object,
set the Face Shield down and turn the Power Switch to the “OFF” position.
Step13: Unplug the Power Cord from the electrical outlet.
3.2.2 Use mild steel wire
The welder can use with mild steel wire and shield gas for welding carbon steel. The
shielding gas should be either pure (100%) CO
2
or a 75% argon-25% CO
2
mixture.
Make sure you use proper welding polarity: as diagram 3-2A., grounding cable connect “-”
terminal, another cable (welding torch cable) connect “+” 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.
Step1: 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
the rust and paint.
Step2: Select the welding current, adjust the position of “MIN/MAX” and “1/2” switch, use higher
welding current for thicker material.
Step3: Check the position of power switch, position must be on “OFF”, then insert the inlet wire to
the socket ( rated current of socket
≥
20A).
Step4: Discharge the nozzle cover and contact tip at the head of welding torch, pull the soft pipe.
Step5: The welding tongs that clamp the rod can’t be contacted with any grounding objects then
turn the
"ON/OFF “switch to “ON” position, the power lamp (green) will light.
Step 6: Press (and hold) the torch button until distance between wire and welding torch is 30mm
loosen torch button.
Step7: Close the power; fix the contact tip and nozzle cover onto the welding torch. (Wire must
through the contact tip and nozzle cover)
