*Do not change Voltage switch position while welding. Wire Speed value in Table is a starting value only, and Wire Speed control setting can be fine tuned during welding.

SECTION 3 – OPERATION

3-1. Controls

1 Wire Speed Control

Use control to select a wire feed

1 speed. As Voltage switch setting in- creases, wire speed range also in- creases.

2 Voltage Switch

The higher the selected number, the thicker the material that can be

2 welded. Do not switch while welding.
