Tweco X415-116 (1040-1113) Classic No. 4 400 Amp MIG Gun

MIG (metal inert gas) guns hold consumable electrode wire and connect to a MIG welder to deliver current to the wire and create an arc between the wire and a metal workpiece. The heat from the arc melts and fuses the workpiece material and the wire material to create a weld.


  • The Industry Standard – for over 40 years
  • Oval-Shaped Handle – reduces grip required to manipulate MIG gun and eases operator fatigue
  • High-Impact Crush-Resistant Handle – uses special plastic composition for long-lasting durability and dependability
  • Heavy Duty Handle – balanced to pivot at center for use in different welding positions 
  • Metal Jacketed Three-Layer Conductor Tube Construction – (copper tube/silicon-resin glass insulator/metal jacket) for improved electrical conductivity
Weight 20 lbs
Dimensions 22 × 5 × 15 in
