  • Page 3 GENERAL SAFETY INSTRUCTION -Wear proper gloves and protective clothing to prevent your skin from being exposed to hot metals, UV and IR rays. -Do not overuse or overheat your welder. Allow proper cooling time between duty cycles. -Keep hands and fingers away from moving parts and stay away from the drive rolls.
  • Page 4 GENERAL SAFETY INSTRUCTION UV and IR Arc Rays The welding arc produces ultraviolet (UV) and infrared (IR) rays that can cause injury to your eyes and skin. Do not look at the welding arc without proper eye protection. -Always use a helmet that covers your full face from the neck to top of head and to the back of each ear.
  • Page 5 GENERAL SAFETY INSTRUCTION Sparks/Flying Debris Welding creates hot sparks that can cause injury. Chipping slag off welds creates flying debris. -Wear protective apparel at all times: ANSI-approved safety glasses or shield, welder’s hat and ear plugs to keep sparks out of ears and hair.

  • Page 21 MIG/MMA WELDER Operating Instructions and Parts Manual 3.1. Angle A can be varied, but in most cases the optimum angle will be 60 degrees, the point at which the torch handle is parallel to the work piece. If angle A is increased, penetration will increase.

Lower your welding helmet and pull the trigger on the torch to start an arc, then begin to drag the torch toward you while simultaneously turning the Wire Speed Dial counter- clockwise.
  • Page 23 MIG/MMA WELDER Operating Instructions and Parts Manual The STRINGER BEAD Is formed by traveling with the torch in a straight line while keeping the wire and nozzle centered over the weld joint (See following figure) The WEAVE BEAD Is used when you want to deposit metal over a wider space than would be possible with a stringer bead.
  • Page 24 MIG/MMA WELDER Operating Instructions and Parts Manual puddle control and allow slower rates of travel speed to achieve deeper penetration. When vertical welding, angle B (see HOLDING THE TORCH) is usually always kept at zero, but angle A will generally range from 45 to 60 degrees to provide better puddle control. OVERHEAD POSITION Is the most difficult welding position.
  • Page 25 MIG/MMA WELDER Operating Instructions and Parts Manual Fillet Weld Joints. Most fillet weld joints, on metals of moderate to heavy thickness, will require multiple pass welds to produce strong joint. The illustrations in Figure 19 show the sequence of laying multiple pass beads into a T fillet joint and a lap fillet joint. 6.5 Spot welding There are three methods of spot welding: Burn-Through, Punch and Fill, and Lap.
  • Page 26 MIG/MMA WELDER Operating Instructions and Parts Manual 6.6 SPOT WELDING INSTRUCTIONS 1. Select the wire diameter and heat setting recommended above for the method of spot welding you intend to use. 2. Tune in the wire speed as if you were going to make a continuous weld. 3.

  • Page 28 MIG/MMA WELDER Operating Instructions and Parts Manual 2.2 Striking the arc EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN. •Never strike an arc or begin welding until you have adequate protection. • Wear flameproof welding gloves, heavy long-sleeved shirt, cuffless trousers, high-topped shoes and a welding helmet or shield.
  • Page 29 MIG/MMA WELDER Operating Instructions and Parts Manual 2.3 Types of weld bead The following paragraphs discuss the most commonly used arc welding beads. The stringer bead Formed by traveling with the electrode in a straight line while keeping it centered over the weld joint. The weave bead Used when you want to deposit metal over a wider space than would be possible with a stringer bead.
  • Page 30 MIG/MMA WELDER Operating Instructions and Parts Manual The horizontal positionis is performed very much the same as the flat weld except that the angle is different such that the electrode, and therefore the arc force, is directed more toward the metal above the weld joint. This more direct angle helps prevent the weld puddle from running downward while still allowing slow enough travel speed to achieve good penetration.
  • Page 31 MIG/MMA WELDER Operating Instructions and Parts Manual A solid weld bead requires that the electrode be moved slowly and steadily along the weld seam. Moving the electrode rapidly or erratically will prevent proper fusion or create a lumpy, uneven bead. To prevent ELECTRIC SHOCK, do not perform any welding while standing, kneeling, or lying directly on the grounded work.
