and top cover aligning the holes in
handle with holes in top cover.

2. Fasten screws through top cover and

into handle.

WHEEL AND AXLE ASSEMBLY

1. Insert axle supports into slots in the

welder housing.

2. Insert axle through the axle supports

and firmly push wheels onto axle.

3. Secure wheel with e-clips and wheel

caps.

GAS CYLINDER BRACKET ASSEMBLY

1. Place bracket on welder aligning the

holes in welder housing.

2. Fasten screws through bracket and

into cabinet.

FOOT ASSEMBLY

1. Place foot on welder and align holes

in the welder housing.

2. Fasten screws through foot into

cabinet.

Ground Clamp

1. Loosen hex nut on work clamp.

2. Insert cord through clamp handle and

slide bare wire under the clamp block.
Tighten hex nut making sure bare
wire is clamped securely (Figure 3).

Wire Installation

Welding power
may be applied to

the output terminals, feed roll, work
clamp, gun cable connection and

WARNING

welding wire even when the the gun
switch is not activated. Do not touch
these parts when the welding machine
is on.

NOTE:

Before installing welding wire,

be sure that the diameter of the
welding wire matches the groove in the
drive roller on the wire feed
mechanism and the wire matches the
contact tip in the end of the gun. A
mismatch on any item could cause the
wire to slip or bind.

1. Verify the unit is off and open the

panel on the welder to expose the
wire feed mechanism.

2. Remove the spool quick lock, by

pushing in and rotating 1/4 turn
counterclockwise. The knob, spring,
and spool spacer can now be removed.

NOTE:

Spool spacer and spindle spacer

act as an 8” spool spindle adapter.
Purchase of an adapter is not necessary.

* See Figure 4 for assembly.

3. Loosen the wire feed tensioning

screw on the drive mechanism. This
allows initial feeding of the wire into
the gun liner by hand.

4. Install the wire spool onto the

spindle so that the wire can come off
the spool on the end closest to the
wire feed guide tube.

Do not cut

the wire loose yet.

Install the spool

spacer, spring, and quick lock knob
by pushing in and turning the knob
1/4 rotation clockwise.

5. Hold the wire and cut the wire end

from the spool. Do not allow the wire
to unravel. Be sure that the end of the
wire is straight and free of burrs.

Wire Feed Arc Welder

6. Feed the wire through the wire feed

guide tube, over the groove in the
drive roll and into the gun liner.
Tighten the wire feed tensioning screw
so that it is snug. Do not over tighten.

7. Remove the nozzle by turning

counterclockwise

. Then unscrew

the contact tip from the end of the
welding torch (See Figure 5). Plug the
welder into the proper power supply
receptacle.

HINT:

Keep torch cable straight when

feeding wire.

8. Turn on the welder and set the wire

speed rate to 5. Activate the gun
switch until the wire feeds out past
the torch end. Turn welder off.

9. Carefully slip the contact tip over the

wire and screw it into the torch neck.
Install the nozzle by turning

clock-

wise

(See Figure 6). Cut the wire off

approximately 1/4” from the end of
the nozzle.

POLARITY

For gas shielded welding, connect the
cable coming out of the torch to the (+)
socket and the ground clamp cable to
the (-) socket on the front panel. For
flux-core (no-gas) welding, connect
torch to (-) and work clamp to (+).

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
