  • The MIG 135 comes with five separate welding modes:
    • MAG welding of mild steel
    • MIG welding of aluminum
    • MIG welding of stainless steel
    • MIG welding of galvanized steel
    • Arc spot welding
  • Ideal for thin sheet metal welding. By utilizing small wire diameters of .025″ and .030″, the MIG 135 is capable of high-speed welding for extremely thin materials, thereby eliminating slow, more tedious TIG processes.
  • Integrated wire spool and torch. Since the wire spool is incorporated in the torch, welding is possible up to 25 feet from the power source (60 feet with option).
  • Small diameter wires of .025″ and .030″ provide support for thin material.
  • Lightweight spool-gun weighs only 2.5 lbs.
  • Quick change wire spools.
