4-1. Controls For 300 Model

1 Power Switch
Fan motor is thermostatically controlled and
only runs when cooling is needed.
2 Voltmeter (see Section 4-3)
3 Ammeter (see Section 4-3)
4 Voltage Adjust Control
Voltage Adjust control is for front panel
adjustment of voltage. Use control to adjust
voltage from 10 to 35 volts.
A remote control provides full range of
voltage output regardless of Voltage Adjust
control setting.

5 Voltage Adjust Control
Control allows selection of either panel or
remote 14 for amperage or voltage control.
6 Arc Control
Control adjusts inductance for MIG welding.
Set Arc Control to desired wire type.
Inductance determines the "wetness" of the
weld puddle. As setting is increased (rotating
Arc Control clockwise), "wetness" (puddle
fluidity) increases. For best results, preset
Arc Control to the wire/electrode type. Then
either increase or decrease setting within
wire/electrode type scale to make any fine
adjustment to the welding arc.
