Installation & Set Up
Section 2
LOCATION
The power supply should be located:
• On a flat, level surfaces with adequate air circulation
• Near the work area to limit welding cable length (shorter lengths are preferred). Avoid looping the weld cables
• In a dry area away from moisture.
• To protect it from grinding dust and other contaminates.
• To provide min. 6” clearance on all sides for cooling.

Extension Cord specifications for incoming power:
If an extension cable is required (one is not recommended) use the following guidelines
Up to 25 ft. (8 meters) use a minimum of 16-3 wire extension cable
30 ft. (10 meters) use a minimum of 14-3 wire extension cable
50 ft. (15 meters) use a minimum of 12-3 wire extension cable
SETTING JUMPER LINKS
The power supply ships pre-wired as 110V. If you plan on using 110V no changes are required. The unit can be configured
to operate on 220V AC . If you would like to wire your unit to operate on 220V the jumper link arrangement (and the
power cord plug) must be changed. NOTE: Charge time will not vary between 110 and 220V.
Incorrect connection of the voltage select jumpers can damage the welding power supply. If you are not comfortable
changing the jumper links seek help from your distributor or a trained electrician.
Remove the power supply lid by unscrewing eight (8) #10 hex head screws (5/16 wrench or nut runner).
The main transformer has configurable jumper links. These are located directly on the main transformer on the top side of
the transformer nearest the rear of the unit. There are two jumper wires connected to the transformer.
DANGER
Always be careful when working inside a capacitor storage unit.
Always disconnect the incoming power line when working inside of electrical
equipment. Even though the power switch is off and the power cable is
disconnected, there can still be voltages inside the unit.
WARNING
DO NOT
operate the power supply without the cover securely in place.
WARNING
DO NOT
defeat the ground on the incoming power cable.
