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.
