Control of Welding Current
DO NOT TURN THE “CURRENT RANGE SELEC-
TOR” WHILE WELDING because the current may
arc between the contacts and damage the switch.
------------------------------------------------------------------------
The “Current Range Selector” provides five overlap-
ping current ranges. The “Fine Current Adjustment”
adjusts the current from minimum to maximum within
each range. Open circuit voltage is also controlled by
the “Fine Current Adjustment” permitting control of the
arc characteristics.
A high open circuit voltage setting provides the soft
“buttering” arc with the best resistance to pop-outs
preferred for most welding. To get this characteristic,
set the “Current Range Selector” to the lowest setting
that still provides the current you need and set the
“Fine Current Adjustment” near maximum. For example: to
obtain 175 amps and a soft arc, set the “Current Range
Selector” to the 190-120 position and then adjust the “Fine
Current Adjustment” for 175 amps.
When a forceful “digging” arc is required, usually for
vertical and overhead welding, use a higher “Current
Range Selector” setting and lower open circuit volt-
age. For example: to obtain 175 amps and a forceful
arc, set the “Current Range Selector” to the 240-160
position and the “Fine Current Adjustment” setting to
get 175 amps.
DO NOT attempt to set the “Current Range Selector”
between the five points designated on the nameplate.
------------------------------------------------------------------------
These switches have a spring loaded cam which
almost eliminates the possibility of setting this switch
between the designated points.
Carburetor Deicing Kit
A carburetor deicing kit is installed on Classic |
welders leaving the factory. The purpose of the
Carburetor Deicing Kit is to prevent carburetor icing
when the outside temperature is 60°F/15.5°c or lower.
See Carburetor Deicing Kit Usage Instructions For
Seasonal Change Over on page B3.
To obtain REPLACEMENT PARTS for the Carburetor
Deicing Kit contact WIS-CON TOTAL POWER COR-
PORATION.

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. The operating speeds
are as follows:
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 runs at the high speed controlled by the
governor.
2. In the “Automatic” / position, the
idler operates as follows:
a. When welding or drawing power for lights or
tools (approximately 100-150 watts minimum)
from the receptacle, 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.
Auxiliary Power
1.75 kw of 120V DC auxiliary power is available at the
receptacle located below the nameplate.
