Description
The Campbell Hausfeld WF1800, WF1900
and WF2000 are 70 amp, single phase
115 volt input, wire feed arc welding
machines. The WF2000 is equipped with
infinite wire speed control to accurately
select the proper wire feed rate needed
for various welding conditions. Internal
components are thermostatically
protected.
This welding system is designed for use
with the Flux Core Arc Welding (FCAW)
process. As delivered from the factory,
this welder can weld with .030” (.8 mm)
or .035” (.9 mm) diameter flux-cored
wire. A starter spool of wire is included.
POLARITY
Welders are configured for DCEN, direct
current electrode negative.
DUTY CYCLE / THERMOSTATIC
PROTECTION
Welder duty cycle is the percentage of
actual weld time that can occur in a ten
minute interval. For example, at a 10%
duty cycle, actual welding can occur for
one minute, then the welder must cool
for nine minutes.
Internal components of this welder are
protected from overheating with an
automatic thermal switch.
A yellow
lamp is illuminated on the front
panel (on/off switch) if the duty cycle
is exceeded
. Welding operations may
continue when the yellow lamp is no
longer illuminated.
MIG CONVERSION
The WF1800 and WF1900 are
NOT
convertible to MIG gas usage. Call 1-800-
746-5641 to purchase conversion kit
(WT600400AJ) for WF2000.
Unpacking
All welding accessories for the
welder are inside the wire feed
compartment. Lift and/or remove
