With remote control connected,
weld output in a CC mode (Stick,

tion of front panel and remote con-
trol voltage/amperage settings. In
CV mode (Wire), weld output is
controlled through remote control

Engine runs at weld/power
speed in Wire mode whenever

sure between pins A and B. In
all other modes, the engine
runs at idle speed until a load is
applied.
