6 welding shields and/or helmets in place. • Do not wear a cracked or broken helmet and replace any cracked or bro-ken filter lenses IMMEDIATELY. • Do not allow the uninsulated portion of the wire feed gun to touch the groundclamp or grounded work to prevent anarc flash from being created on contact...

7 prevent spatter or slag from falling into ear. • Make sure welding area has a good,solid, safe floor, preferably concrete ormasonry, not tiled, carpeted, or made ofany other flammable material. • Protect flammable walls, ceilings, andfloors with heat resistant covers orshields. • Check welding are...

8 • Do not expose cylinders to electricity ofany kind. • Do not use a cylinder or its contents foranything other than its intended use. Donot use as a support or roller. • Do not locate cylinders in passagewaysor work area where they may be struck. • Do not use a wrench or hammer to opena cylinder v...

9 WELDER SPECIFICATIONS DESCRIPTION Your new MIG (GMAW) flux core (FCAW)wire feed welder is designed for mainte-nance and sheet metal fabrication. Thewelder consists of a single-phase powertransformer, stabilizer, rectifier, and aunique built-in control/feeder. Now you can weld sheet metal from 24ga...

10 KNOW YOUR WELDER Handle – Rugged, top mounted handle allows for easy transport of your welder. Wire Speed Control – Use this dial to adjust the speed at which the welder feeds wire to thegun. 1 is the slowest wire feed speed, 10 is thehighest. You will need to adjust or “tune-in”your wire speed f...

11 POWER SOURCE CONNECTION POWER REQUIREMENTS This welder is designed to operate on a proper-ly grounded 230 volt, 60Hz, single-phase alter-nating current (AC) power source fused with a50 amp time delayed fuse or circuit breaker. Itis recommended that a qualified electrician ver-ify the ACTUAL VOLTA...

Install the dark glass by sliding it into place behind the glass retaining tabs. Note: if your face shield was supplied with a3” x 3.8”...

14 Change the drive roller according to the follow-ing steps: 1. Open the door to the welder drive com- partment. 2. Remove the drive tension by loosening the tension adjusting screw and lifting the DriveTension Adjustor up, away from the DriveTension Arm. Pull the drive tension armaway from the dri...

16 16. Set the WIRE SPEED control to the middle of the wire speed range. 16. Straighten the gun cable and pull the trigger on the welding gun to feed thewire through the gun assembly. 17. When at least an inch of wire sticks out past the end of the gun, release the trigger. 18. Select a contact tip ...

17 B. For MIG (GMAW) welding, mount the Ground Clamp ring terminal to the “-” mounting post and the Torch ringterminal to the “+” mounting post. See configuration shown in Figure 9. 2. Attach the ground clamp to the work piece, making sure that it is cleaned ofdirt, oil, rust, scale, oxidation, and ...

18 piece farthest away from you, and at anangle similar to that which will be usedwhen welding. (SEE HOLDING THE GUNon page 18 if you are uncertain of theangle at which you will be welding) 4. With your free hand, turn the Wire Speed Dial to maximum and continue to holdonto the knob. WARNING EXPOSUR...

19 2. Angle B (Figure 11) can be varied for two reasons: to improve the ability to see thearc in relation to the weld puddle and todirect the force of the arc. The force of the welding arc follows astraight line out of the end of the nozzle. If angle B is changed, so will the direction ofarc force a...

20 For most welding jobs you will pull the gunalong the weld joint to take advantage ofthe greater weld puddle visibility. 2. TRAVEL SPEED is the rate at which the gun is being pushed or pulled along theweld joint. For a fixed heat setting, thefaster the travel speed, the lower the pen-etration and ...

21 force, is directed more toward the metalabove the weld joint. This is to help preventthe weld puddle from running downwardwhile still allowing slow enough travel speedto achieve good penetration. A good start-ing point for angle B is about 30 degreesDOWN from being perpendicular to thework piece....

22 The illustrations in Figure 19 show thesequence for laying multiple pass beads intoa single V butt joint. NOTE: WHEN USING SELF-SHIELDING FLUX-CORE WIRE it is very important to thor-oughly chip and brush the slag off each com-pleted weld bead before making anotherpass or the next pass will be of ...

23 the top piece of metal and the arc isdirected through the hole to penetrateinto the bottom piece. The puddle isallowed to fill up the hole leaving a spotweld that is smooth and flush with thesurface of the top piece. Select the wire diameter, heat setting, andtune in the wire speed as if you were...

24 Note: Due to inherent variances in flux- cored welding wire, it may be necessary touse a contact tip one size larger than yourflux core wire if wire jams occur. 1. If the wire burns back into the tip, remove the tip from the gun and clean the holerunning through it with an oxygen-acety-lene torch...
