WELDING OPERATION
GENERAL INFORMATION
The Classic II can deliver from 40 to 325 amps of con-
stant current for DC stick welding or DC semiautomat-
ic wire feed welding (with wire feed module). DC TIG
welding is possible across the entire range from 40 to
325 amps. Output can be adjusted by setting the CUR-
RENT RANGE SELECTOR and the FINE CURRENT
ADJUSTMENT on the output control panel to the set-
tings that are best for your selected welding process.
IDLER OPERATION
Start the engine with the IDLER switch in the "HIGH"
position. Allow it to run at high idle speed for several
minutes to warm the engine. See
Specifications in the Installation section for operating
speeds.
The idler is controlled by the IDLER toggle switch on
the welder control panel. The switch has two positions
as follows:
1 . In the "HIGH" position, the idler is off, and the
engine high speed is controlled by the governor.
2.
In the "AUTO" position, the idler operates as fol-
lows:
a.
When welding or drawing power for lights or
tools (approximately 100-150 watts minimum)
from the receptacles, the engine operates at
full speed.
b.
When welding ceases or the power load is
turned off, a preset time delay of about 15 sec-
onds starts. This time delay cannot be adjust-
ed.
c.
If the welding or power load is not re-started
before the end of the time delay, the idler
reduces the engine to low idle speed.
