For Sck/Arc/MMA Welding:
1. Wear our auto darkening welding helmet and gloves to protect your eyes and hands from any
harmful welding arc. (Please see step 1 in Plasma Cung.)
2. You don’t need to connect the machine to any gas or air supply. It’s a plug and play.
Panel connecon instrucons:
- Set TIG Weld/Sck Weld/Plasma Cut to Sck Weld mode (refer to Figure 1.4, page 2).
- Set “2.5S/5S” to “2.5S” mode.
- Set “Machine/PEDAL” to “Machine” mode.
- Adjust current dial between 10 and 200 amps (Figure 1.11).
Please be sure to turn o the machine when you switch from one funcon to another.
This is important, because otherwise the machine could be damaged.
