In mig welding you can easily join a variety of.
The most common types of mig wire for welding mild steel are er70s 3 and er70s 6.
It is also the best choice for avoiding silicon.
For example for 030 inch wire multiply by 2 inches per amp to find the wire feed speed in inches per minute ipm.
Welding is basically a process of joining two metal pieces there are various welding methods being adopted by professional and the most common types of welding are stick tig and mig welding.
