Pair these guns with a welder to direct, start, and stop the flow of MIG welding wire and electric current to the spot you're welding. Match the maximum current of the guns to the maximum output current of your welder.

Spool Gun—Spool MIG guns house welding wire in the gun, closer to where you’re welding, rather than in the machine. Often used for welding aluminum, they prevent soft wire from kinking in your cable since it doesn’t have to travel as far.

Water Cooled—Water-cooled guns cool more efficiently than air-cooled guns to prevent overheating, even when welding continuously or for long periods of time.

Tweco—Tweco guns come with connectors so you can attach them to welders from multiple manufacturers.
