Shielded Metal
Arc Welder

 

CAMPBELL

HAUSFELD

This line of Campbell Hausfeld Arc
Welders is designed to be used on
standard 115V household current.  These
welders are equipped with infinite
amperage control to accurately select the
proper current needed for various
welding conditions. Internal components
are thermostatically protected.

This welder can weld up to 1/8” steel in
a single pass. Recommended electrode
size is 1/16” diameter for 15 amp
circuits, up to 5/64” diameter for 20
amp circuits. For replacement
electrodes, call (800) 746-5641 for the
nearest dealer.

Unpacking

When unpacking, inspect carefully for
any damage that may have occurred
during transit. Report any damaged or
missing items by calling 1-800-746-5641.

Circuit Requirements

This equipment 
requires a

dedicated 115 volt circuit. Refer to the
following chart for the correct circuit
breaker or fuse rating. Do not run
other appliances, lights, or tools on
this circuit while operating this
equipment. Extension cords are not
recommended. Blown fuses or tripped
circuit breakers can result from failure
to comply with this recommendation.

Components and Controls

1. Work Clamp - connect to work piece

2. Electrode Holder - holds electrode

welding rod

3. Power Cord - plug into 115 volt outlet.

4. On/Off Switch - lights if thermostat

has automatically shut unit off.

5. Infinite Amperage Control Knob -

turns clockwise to increase amperage
and counterclockwise to decrease
amperage.

6. Welding Amp Indicator - as the

amperage control knob (5) is rotated,
the amperage indicator moves
displaying approximate weld amps.
