Shielded Metal
Arc Welder
IN973900AV 6/09
Description
These Campbell Hausfeld electric arc
(stick) welding machines run on 230
volt, single phase input power. These
welders are equipped with infinite
amperage control to accurately
select the proper current needed for
various welding conditions. Internal
components are thermostatically
protected.
These welding systems are designed
for use with the Shielded Metal Arc
Welding (SMAW) process. As delivered
from the factory, these welders can
weld with up to 5/32 inch diameter
electrodes.
Model WS4369 is an AC output welder.
Model WS4469 is an AC and DC output
welder. There are two levels of AC
output on each machine. The cable with
the ground clamp is inserted into the
AC COM socket and the cable with the
electrode holder is inserted into the
AC LO or AC HI socket, depending on
the output current range needed. The
WS4469 has two extra sockets labeled
DC+ and DC-. The cables are connected
to these sockets for DC welding. The
polarity is dependent on the output
needed. Do not try to use more than
one pair of sockets at a time.
