Product Description

The Smarter Tools MIG-135 Welding Kit is the perfect choice to do projects and repairs around the home, farm and shop. This MIG welder will produce a cleaner bead with less splatter than a regular flux core wire welder. The welder runs off of a standard 120 volt household outlet and produces an output range of 20-135 amps. It uses standard flux-core wire (E71-GS) or steel wire 0.6mm, 0.8mm, 0.9mm in diameter and has 4 heat settings to easily adjust the output according to the thickness of metal you are welding. The welder can easily switch between gas-less flux-cored welding for deep penetration on thick steel or gas-shielded MIG welding on thin-gauge steel, stainless steel or aluminum. Package includes: MIG-135 welding power source, MIG torch with 8ft. (2.44m) lead, ground clamp with10ft. (3m) lead, 2 extra contact tips, a 1lb spool of flux wire, a 2lb spool of MIG wire, 0.6mm and 0.8mm (0.025 in. and 0.031 in.) drive roll, 0.9mm and 1.0mm (0.035 - 0.040 in.) drive roll, an adjustable gas regulator with a hose, ST-1S Auto-darkening welding helmet, gloves, users manual, and welding cart.


  • Wide 20 - 135 Amp welding output range-Perfect for completing projects and repairs around the home, farm, shop, or basic auto-body welding
  • Step-less wire speed control-More reliable welds
  • Thermal overload protection-Ensures lasting performance for years to come
  • Multiple voltage settings-For a variety of materials and thicknesses
  • Tool-less Design-Easily change wire, drive rolls and polarity
  • Operates on 120V/20A-Standard household outlet
  • 3/16 in. single-pass or 5/16 in. multi-pass welding capacity with flux-cored wire
  • Easily switches between gas-less flux-cored welding for deep penetration on thick steel or gas-shielded MIG welding on thin-gauge steel, stainless steel or aluminum


What Can it Be Used For?

Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding and Flux-cored arc welding (FCAW or FCA) up to 135A
