RECOMMENDED APPLICATIONS
WELDER
The Classic III and Classic IIID provide excellent con-
stant current DC welding output for stick (SMAW) weld-
ing and for DC TIG welding. When equipped with the
wire feed module, they also offer constant voltage out-
put for DC semiautomatic wire feed welding. For more
details on using the machine as a welder, see
Operation in the Operation section of this manual.
GENERATOR
The Classic III and Classic IIID are also capable of pro-
viding 3.0 kVA of 115/230 volts of 60 Hertz AC auxiliary
power.
OPERATIONAL FEATURES AND
CONTROLS
The Classic III and Classic IIID are designed for sim-
plicity. Therefore, it has very few operating controls.
Two controls are used for welding operations:
• A five-position CURRENT RANGE SELECTOR
switch selects current output ranges for constant cur-
rent stick or TIG applications and constant voltage
wire feed applications (with optional Wire Feed
Module - see the
Accessories section)
• A FINE CURRENT ADJUSTMENT control for fine
adjustment of current from minimum to maximum
within each range
Controls for the engine include a two-position
IGNITION ON/OFF toggle switch, a START push-
button, and a two-position IDLER switch that selects
engine speed for welding or auxiliary power applica-
tions. See
Engine Operation in the Operation section
of this manual for details about starting, running,
stopping, and breaking in the engine.
