6.2.2. Operation
1. Switch the power on at the back of the machine — the LED power indicator will
light up and you will hear the fan start to work.
2. Open the gas cylinder valve and adjust the flow meter to the desired position.
3. Turn the conversion switch on the front of the machine to the “MIG welding”
position and adjust the voltage and wire feed speed appropriately.
4. Adjust the burnback control on the internal panel to ensure the required length
of wire protrudes out of the contact tip after welding.
5. Press the switch on the welding torch and begin welding.
6. The gas cuts off automatically one second after the arc is stopped.
6.3. MIG welding without gas
6.3.1. Set up
1. Connect the welding torch to the output socket on the front panel of the
machines and tighten it.
2. Connect the earth return to the negative (-) terminal on the front panel of the
machine.
3. Insert the dix plug on the wire feeder into the “NO GAS” output socket on the
internal panel and tighten it clockwise.
4. Fix the welding wire coil to the rack axis on the wire feeder, ensuring that the
groove in the wire feed wheel is aligned with the torch wire feed hole.
5. Unfasten the tensioner on the wire-pressing wheel and feed the wire into the
appropriate groove in the wire feed roller, pressing it in securely but not too
tightly.
NOTE: ensure the correct roller is fitted i.e. 0.8mm
wire needs a 0.8mm
groove on the roller.
6. Thread the wire into the welding torch manually and then press the wire feed
button to feed it out of the end of the torch.
