6-1. Controls

250 650-A

1 Wire Speed Control

Control varies the rate of wire being fed through the welding gun.

2Power Switch/Supplementary Protector

Turns power on and off. Also, this switch functions as supplementary protector CB1.

CB1 protects unit from overload. If CB1 opens, unit shuts down.

Reset power switch/supplementary protector.

3 Voltage Control

Control varies the voltage level of the welding arc. The voltage range is 4 (minimum) to 7 (maximum) on 115 VAC and 1 (minimum) to 7 (maximum) on 230 VAC.

.Switch must “click” into detent position. DO NOT switch under load.

4 Over Temperature Light

Light illuminates if main transformer overheats.

5Gun Trigger Receptacle

6Trigger Switch

When pressed, energizes wire feed motor and gas valve for shielding gas flow.
