Mig Welding Sheet Metal Settings

For thinner gauge sheet metal like 18 or 20 gauge we suggest 023 6mm wire in your mig welder.

Mig welding sheet metal settings.

Keep in mind during the welding process it is important to direct the arc right at the center of the weld puddle and don t do movements like whipping or weaving as it may cause warping and burn through quickly. If you take your time following these steps then you will have a much easier time welding. Mig welding electrode selection chart. Holding the tip too far from the surface will cause the wire to have to come out too far to touch the metal.

I keep blowing through my thin sheet. Keep the stick out short stickout of your mig wire is important when welding any type of metal but especially sheet metal. Finally i have guided you through 3 main settings in a mig welder and provided the recommended parameter charts. Short circuit transfer mig short arc tig and pulsed tig welding processes provide the most control over the heat to address these challenges.

And when it comes to mig welding setting there are only 3 main settings that you need to set before you begin the welding process. It should also be set in the position that you will be welding in. Andy gives helpful insights and tips to mig weld thin sheet metal. Try to set proper mig welding settings for mild steel along with other kinds of metals.

Metal thickness amperage settings. When welding mild steel a good rule of thumb is to set the amperage level at 1 amp for every 0 001 of thickness. Learn why mig pulsed mig tig and pulsed tig are the ideal choices when welding sheet metal. Test your settings on a piece of scrap metal that is very close to the thickness of the metal that you will be welding.

So if you are welding 12 gauge mild steel with a thickness of 0 100 you would set the machine at 100 amps. The optimal gas pressure varies a little but it should be around 15 25 cfh.
