Wire Installation
Welding power may be applied to
the output terminals, feed roll, work clamp, gun cable connection and
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.
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.

For gas shielded welding, connect the cable coming out of the torch to the (+) socket and the ground clamp cable to the
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
