Campbell Hausfeld WG2020 - Manual (Page 4)

1. Loosen hex bolt on work clamp.
2. Insert cord (labeled work on the
front panel of the welder) through
clamp handle and slide bare wire
under the clamp block. Tighten hex
bolt making sure bare wire is
clamped securely (Figure 3).
Welding power
may be applied to
output terminals, feed roll, work clamp,
gun cable connection and welding wire
even when gun switch is not activated.
Do not touch these parts when welding
machine is on.
NOTE: Before installing welding wire,
be sure:
a. The diameter of welding wire
matches the groove in drive roller
on wire feed mechanism.
b. The wire is compatible with the
diameter line in gun hose.
c. The wire matches tip in end of
gun.
A mismatch on any item could cause the
wire to slip and bind.

Wire Feed Arc Welder
LOCATION
Selecting the proper location can
significantly increase performance,
reliability and life of the arc welder.
● For best results locate welder in a
clean and dry environment. Dust
and dirt in the welder retain
moisture and increase wear of
moving parts.
● Place welder in an area with at least
twelve inches (305 mm) of
ventilation space at both the front
and rear of unit. Keep all
obstructions out of this ventilation
space.
● Store flux core wire in a clean, dry
location with low humidity to
preserve the flux coating.
● Use a properly grounded receptacle
for the welder and ensure welder is
the only load on power supply
circuit. Refer chart on page 1 for
correct circuit capacity.
● Use of an extension cord is not
recommended for electric arc
welding machines. Voltage drop in
the extension cord may significantly
degrade performance of the
welder.
All welding accessories for the
welder are inside wire feed
compartment. Lift and remove wire
feed cover to find handle,
workclamp, etc.
1. Slide handle into plastic ends as
shown (Fig. 2).
2. Place handle assembly on welder
aligning two holes in plastic ends
with threaded holes in welder
housing.
3. Use washers and fasten screws
through handle ends and into
cabinet.
4. Attach cylinder base to unit as shown
(Fig. 2).
1. Verify unit is off and lift welder
panel to expose wire feed
mechanism.
2. Remove the spool quick lock by
pushing in and rotating 1/4 turn
counterclockwise. Then remove
knob, spring and spool spacer.
3. Loosen wire feed tensioning screw
on drive mechanism. This allows
initial feeding of wire into gun liner
by hand.
4. Install wire spool onto spindle so
wire can come off spool on the end
closest to the wire feed guide tube.
Do not cut the wire loose yet.
Install spool spacer, spring and quick
lock knob by pushing in and turning
knob 1/4 rotation clockwise.
5. Hold wire and cut the wire end from
spool. Do not allow wire to unravel.
Be sure end of wire is straight and
free of burrs.
6. Feed wire through wire feed guide
tube, over the groove in drive roll
and into gun liner. Snugly tighten
wire feed tensioning screw. Do not
over tighten. Install outer welder
panel.
7. Remove nozzle by turning clockwise
while pulling off, then unscrew
contact tip from end of welding
torch (See Figure 5). Plug welder into
a proper power supply receptacle.
8. Turn on welder and set wire speed
rate to 5. Activate gun switch until
wire feeds out past the torch end.
Turn welder off.
