automatic and automatic welding processes using Fabco
or Tubular wire.
POSITIVE SHIELDED METAL ARC WELDING

Welding Terminals
MODE SELECTOR SWITCH - This control is not
located below the control panel, on the right-hand
side of the lower panel. This handle, when in the UP
position, places the machine in CC mode, and when
in DOWN position, in CV mode.
CONTACTOR CONTROL - This item is not shown,
but is a timer used to control the length of meltback
time to prevent wire electrode from "freezing'" to the
weld puddle.
VOLTAGE REGULATOR The voltage regulator,
not shown, maintains the exciter voltage to within
5%.
