Spool Gun

Pair these guns with a welder to direct the flow of MIG welding wire and electric current. With no need for a filler rod, MIG welding is faster than TIG welding, and ideal for thick base metals, including iron beams and carbon steel. At four pounds or less, our MIG guns are comfortable to hold, ensuring steady-handed results with every job. Guns with longer duty cycles can weld at their full amperage for longer periods of time without overheating.

Check the max current amperage and manufacturer of your welder. Using a gun with a higher amperage than your welder can cause damage to both.

Spool Gun—Spool MIG guns house wire in the gun, closer to where you’re welding, rather than in the welder itself. 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 cycle water through the cable and the neck of the gun, which transfers the excess heat back to a radiator. This cools more efficiently than air-cooled guns, so you can weld for longer without stopping due to overheating.

MIG Gun Contact Tips

Attach these tips to MIG guns to guide welding wire and electric current to the weld site.

Tapered Tip—Tapered tips are good for welding on edges and in tight spaces, such as corners.
