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.
Some arc instability may be experienced with EXX10
electrodes when trying to operate with long arc tech-
niques at settings at the lower end of the open circuit
voltage range.
CAuTION
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.

Auxiliary Power

The AC auxiliary power, supplied as standard, has a
rating of 2400W of 120 VAC (60 hertz).
With the 2400W, 120 VAC auxiliary power one 120V
duplex grounding type receptacle is provided. The cir-
cuit is protected with one GFCI with breaker.
The rating of 2400W permits a maximum continuous
current of 26 amps that can be drawn from the 120
volt duplex receptacle. The 120 volt duplex receptacle
or GFCI has a configuration which permits 20 amps to
be drawn from either half. The total combined load of
the duplex receptacle or GFCI is not to exceed
2400W.
If a GFCI is tripped, See the MAINTENANCE section
for detailed information on testing and resetting the
GFCI.
OPERATION
If auxiliary power is used simultaneously with weld-
ing, the current which can be used while maintaining
voltage regulation within 10% is as follows:
