wire to slip and/or bind.
NOTE: Always maintain control of loose
end of welding wire to prevent
unspooling.
1. Verify unit is off and open door
panel to expose wire feed
mechanism.
2. Remove the spool lock by pushing in
and rotating 1/4 turn
counterclockwise. Then remove lock,
spring and retainer.
3. Flip tensioning knob down and
swing arm up on drive mechanism.
This allows initial feeding of wire
into torch liner by hand.
4. Install wire spool onto spindle so
wire can come off bottom of spool.
Do not cut the wire loose yet.
Install retainer, spring and lock by
pushing in and turning lock 1/4

Installation
LOCATION
Selecting the proper location can
significantly increase performance,
reliability and life of the arc welder.
l 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.
l 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.
l Store welding wire in a clean, dry
location with low humidity to
prevent oxidation.
l Use a properly grounded receptacle
for the welder and ensure welder is
the only load on power supply
circuit. Refer to chart on page 1 for
correct circuit capacity.
l 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.
Assembly
WIRE INSTALLATION
NOTE: Before installing welding wire,
be sure:
a. Diameter of welding wire matches
groove in drive roller on wire feed
mechanism (See Figure 2).
b. Wire matches contact tip in end of
torch (See Figure 3).
A mismatch on any item could cause the
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 guide, over the
groove in drive roller and into torch
wire liner. Flip swing arm down and
tension knob up. Adjust tension by
rotating tension knob.
7. Unscrew nozzle and contact tip from
end of welding torch (See Figure 3).
Plug welder into a proper power
supply receptacle.
8. Turn on welder and set wire speed
to 10. Activate torch trigger until
wire feeds out past the torch end.
Turn welder off.
9. Carefully slip contact tip over wire,
screw tip into torch end and
reinstall nozzle (See Figure 3). Cut
wire off approximately 1/4 inch
from nozzle end.
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 20%
duty cycle, actual welding can occur for
two minutes, then the welder must cool
for eight minutes.
Internal components of this welder are
protected from overheating with an
automatic thermal switch. A red lamp is
illuminated on the front panel if the
