7.Unscrew nozzle and 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 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 5). 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.

WIRE INSTALLATION
NOTE: Before installing welding wire, be sure:
a. Diameter of welding wire matches groove in drive roller on wire feed mechanism (See Fig. 4).
b. Wire matches contact tip in end of torch (See Fig. 5).
A mismatch on any item could cause the 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 spool bottom of spool. Do not cut the wire loose yet. Install spool retainer, spring and lock by pushing in and turning lock 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 guide, over the groove in drive roller and back into wire guide. Flip swing arm down and tension knob up. Adjust tension by rotating tension knob.
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 duty cycle is exceeded. Do not switch unit off. This will allow the internal fan to cool the unit quickly. Welding operations may continue when the red lamp is no longer illuminated.
OVERLOAD PROTECTION
The welder is equipped with a circuit breaker which protects the machine if the maximum output is exceeded, such as when the output is
