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.
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.
