How to Spot Weld With a MIG

Spot weld with MIG welder.

The skill of welding can come in very handy for a variety of metal and mechanical projects. To properly weld two pieces of metal together, you will need to spot weld the pieces the way you want them lined up before you run the final weld bead over the metal pieces. To spot weld with a metal inert gas (MIG) welder, all you have to do is pull a trigger on the MIG welder gun and begin to weld.

Things You'll Need

• Steel clamps
• MIG welder
• Welding helmet
• Leather gloves

Instructions

1. Line up the pieces of metal you want to weld together the way you want them positioned.

2. Clamp the pieces together with steel clamps, which won't melt from the MIG welder's extreme heat.

3. Turn on the MIG welder.

4. Put on your leather gloves and welding helmet.

5. Position the MIG welder gun a half inch over an end of the seam between the pieces of metal. To spot weld you want to just weld literally a spot at the ends of the seam you plan to run a full weld bead on.

6. Lower your welding helmet and pull the welder gun trigger for 3 seconds and let go of the trigger. To spot weld you want to just weld literally a spot at the ends of the seam you plan to run a full weld bead on.

7. Pull up your welding helmet and position the welder gun over the other end of the seam you need to spot weld and repeat step 6.
