3-2. Front panel instruction
1. MMA/MIG button. Press it to change the welding mode of MIG or MMA. The indicator would
light on.
2. 2T/4T button. The description as follows.
2T mode applies to spot welding. The welding machine starts working by press the torch
switch, and stops when release it.
4T mode is suitable for long time welding. The arc current starts when pressing the torch switch
first time. Then the machine welds by release the switch. The crater current occurs when
press the switch again, and the machine stops welding when release it.
3. Voltage adjustment knob. Adjust the range of output voltage.
4. Current adjustment knob. Adjust the range of output current.
5. Electric arc characteristic knob. Adjust the soft/hard range of the electric arc to achieve
perfect welding performance.
3-3. Polarity conversion joint
This machine has the polarity conversion; There are positive output terminal and negative output
terminal between wire feeder and wire spool; When use solid wire with gas protection, torch
socket should be connected to the positive output terminal, ground cable should be connect-
ed to the negative output terminal; When use flux-cored wire, the two connected cable should
be exchanged.
