ARC GOUGING
The RANGER 305G can be used for limited arc goug- ing. For optimal performance, set the MODE switch to
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" | |
5/32" | |
3/16" | |
1/4" |
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
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
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).
