Notes
General Safety (Continued)
●Keep the head and face out of the welding fumes.
●Do not perform electric arc welding operations on metals that are galvanized or cadmium plated, or contain zinc, mercury, or beryllium without completing the following precautions:
a.Remove the coating from the base metal.
b.Make sure that the welding area is well ventilated.
c.Use an
Extremely toxic fumes are created when these metals are heated.
!WARNING
The electromagnetic field that is generated during arc welding may interfere with the operation of various electrical and
electronic devices such as cardiac pacemakers. Persons using such devices should consult with their physician prior to performing any electric arc welding operations.
●Route the wire gun and work cables together and secure with tape when possible.
●Never wrap arc welder cables around the body.
●Always position the wire gun and work leads so that they are on the same side of the body.
●Exposure to electromagnetic fields during welding may have other health effects which are not known.
Always be sure
! WARNING that the welding area is secure and free of hazards (sparks, flames, glowing metal or slag) prior to leaving. Be sure that equipment is turned off and excess wire is cut off. Be sure that cables are loosely coiled and out of the way. Be sure that all metal and slag has cooled.

Installation
LOCATION
Selecting the proper location can significantly increase performance, reliability and life of the arc welder.
●For best results locate the welder in an environment that is clean and dry. Dust and dirt in the welder retain moisture and increase wear of moving parts.
●Place the welder in an area that provides at least twelve inches (305 mm) of ventilation space at both the front and rear of the unit. Keep all obstructions away from this ventilation space.
●Store flux cored wire in a clean, dry location with low humidity to reduce oxidation.
●The receptacle used for the welder must be properly grounded and the welder must be the only load on the power supply circuit. Refer to the Circuit Amps chart on page 1 for correct circuit capacity.
●The use of an extension cord is not recommended for electric arc welding machines. The voltage drop in the extension cord may significantly degrade the 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 Fig. 2). The drive roller is marked with metric sizes:
.6mm = .024”, .8
.035”
b. Wire matches contact tip in end of gun. (See Fig. 3).
A mismatch on any item could cause the wire to slip and 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 quick lock by pushing in and rotating 1/4 turn counterclockwise. Then remove knob, spring and spool spacer.
3.Flip tensioning screw down 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 roller and into gun liner. Flip tensioning screw up and adjust tension by rotating tensioning screw knob. Do not overtighten.
7.Remove nozzle by turning counter- clockwise, then unscrew 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 rate to 10. Activate gun trigger until wire feeds out past the torch end. Turn welder off.
9.Carefully slip contact tip over wire and screw tip into torch end. Install nozzle by turning clockwise (See Figure 3). Cut wire off approximately 1/4 inch from nozzle end.
