6-8. Remote Voltage/Amperage Control

1 Remote Receptacle RC4

Connect optional remote voltage/ amperage (V/A) control to RC4 (see Section 5-7).

With remote control connected, weld output in a CC mode (Stick, TIG) is determined by a combination of front

1panel and remote control voltage/ amperage settings. In CV mode (Wire), weld output is controlled

through remote control only.

2 Remote Hand Control (Optional)

3 Remote Foot Control (Optional)

. Engine runs at weld/power speed in Wire and TIG mode whenever a device connected to the remote receptacle makes closure between pins A and B.

This unit does not have remote contactor control. Output is al- ways on.

In Example:

Process = Stick (Using Remote On/Off)

Min = 20 A CC/DC

Max = 160 A CC/DC
