How to improve mig welding. Then choose your gas flow. Typically for 035 and 045 wires thats between 330 ipm and 450 ipm. To get good fusion you need both the filler metal and the base metal to melt and fuse together to make a good weld.

Select a wire-feed speed range thats the sweet spot for welding. This is easy MIG welding techniques require you to use a reverse polarity DC electrode positivity on some machines. Officially it is designated as GMAW - Gas Metal Arc Welding.

High speed can create a burn-through and fast popping sound whereas low speed causes the wire to burn too slow and forms an unstable arc. The same idea holds true for MIG welders. Today we are going to begin the process of teaching ourselves how to MIG weld.

Youll find these settings typically on the interior of the machine. The still popular name MIG Metal Inert Gas was initially adopted when the inert gases used to weld aluminum were only argon or helium. The second is backhand method where you drag the MIG gun like a Stick welder.

Welding is hazardous if not carried out appropriately. MIG welders should ensure they have worn protective clothing before embarking on welding. Pulsed MIG welding lowers heat input and makes it easier to weld thin materials and minimize burn-through.

Select a wire diameter at the optimum wire feed speed. So what you want to do is maintain a short wire stick-out and stay ahead of the weld and keep the mig welding wire on the leading edge of the puddle. Carefully feed in the new liner down the torch lead all the way to exit the torch neck.
