ARC GOUGING
The RANGER 305G can be used for limited arc goug-
ing. For optimal performance, set the MODE switch to
CC-STICK and the ARC CONTROL to +10.
Set the CONTROL knob to adjust output current to the
desired level for the gouging electrode being used
according to the ratings in the following table.
Electrode Diameter
Current Range (DC, electrode
positive)
1/8" 30-60 Amps
5/32" 90-150 Amps
3/16" 150-250 Amps
1/4" 250-305 Amps
AUXILIARY POWER:
Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
regardless of the welding control settings providing no
welding current is being drawn.
The auxiliary power of the RANGER 305G consists of
two 20 Amp-120 VAC (5-20R) duplex receptacles and
one 50 Amp 120/240 VAC (14-50R) receptacle. The
240 VAC receptacle can be split for single phase 120
VAC operation.
The auxiliary power capacity is 9,000 watts of 60 Hz,
single phase power. The auxiliary power capacity rat-
ing in watts is equivalent to volt-amperes at unity
power factor. The max permissible current of the 240
VAC output is 38 Amps.
The 240 VAC output can be split to provide two sepa-
rate 120 VAC outputs with a max permissible current
of 38 Amps per output to two separate 120 VAC
branch circuits (these circuits cannot be paralleled).
Output voltage is within ± 10% at all loads up to rated
capacity.
The 120 V auxiliary power receptacles should only be
used with three wire grounded type plugs or approved
double insulated tools with two wire plugs. The current
rating of any plug used with the system must be at
least equal to the current capacity of the associated
receptacle.
NOTE: The 240 V receptacle has two circuits, each of
which measure 120 V to neutral but are of opposite
polarities and cannot be paralleled.
Simultaneous Welding and Auxiliary Power Loads
The above auxiliary power ratings are with no welding
load. Simultaneous welding and power loads are
specified in the following table. The permissible cur-
rents shown assume that current is being drawn from
either the 120 VAC or 240 VAC supply (not both at the
same time).
