Match feedroll groove to diameter of wire being used. Set Tension Knob Setting to 3 at start.

Adjust tension per instructions in the manual.

CAUTION! Do not change Voltage switch position while welding. See owners manual for more information.

*Multiple passes required. **Aluminum wire is soft so feedability is not as good.
