6.3.2. 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. Turn the conversion switch on the front of the machine to the “MIG welding”
position and adjust the voltage and wire feed speed appropriately.
3. Adjust the burnback control on the internal panel to ensure the required length
of wire protrudes out of the contact tip after welding.
4. Press the switch on the welding torch and begin welding.
6.4. Changing the feed roll groove
The feed roll groove is factory set for welding filler wires of 0.8-1.0mm diameter.
The feed roll groove must be changed if you use 0.6mm filler wire.
1. Open the feed roll using the pressure control lever.
2. Switch the machine on from the main switch.
3. Press the welding gun trigger and drive the feed roll in such a position that the
locking screw is up and can be opened.
4. Switch off the machine using the main power switch.
5. Open the feed roll locking screw by approximately half a turn using a 2.0mm
Allen key.
6. Pull the feed roll from its shaft.
7. Turn the feed roll and reinstall it, making sure that the screw is on the same
level as the shaft.
8. Tighten the feed roll locking screw.
