Why can''t I use MIG to weld stainless steel or aluminium? …
You can. But you’ll need to modify your MIG welder. You’ll need an aluminium weld kit for your Mig welder, it uses different wire (obviously) and as memeory serves, a different gas. I’m almost certain that you’ll be able to do stainless as well, i
🥇Top 9 Best MIG Welder Reviews & Buyer Guide of 2020
As you know, there is a welding wire in each of this welder. The thickness of this very part plays a wide impact on the game. Let me give you some ides from the AWS classifiion of wires, there are two kinds of them. The ER70S-3 and the ER70S-3. The first
Hi. I own an HTP 140 amp mig welder, after buying a welding book, I tried to practice some welding. I got a piece of 1/8 inch mild steel and tried to butt weld it together. I had the setting on the highest level, I had a good stable arc, and used a forehand weld (about 15
Different types of welding and what they are used for
Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply. MIG welding is usually the welding of choice for DIY enthusiasts and hobby welders who don’t have the money to spend on expensive equipment.
The Basics: MIG Troubleshooting | Bernard
If the welding specifiions allow, decrease the drive roll tension, use a larger diameter wire and/or reduce the distance the wire feeds (use shorter cables) to minimize the chance of nesting. If the wire melts back and fuses with the contact tip, as shown, the tip should be replaced and the drive rolls checked for a nest before continuing to weld.

Plant Engineering | Selecting a filler metal: Seven factors …
For instance, when welding on thin material, it is important that the arc characteristics are appropriate—a wire that provides deep penetration may cause the welding operator to burn through. On the other hand, if the part to be welded is thick and features a single "V" joint, a filler metal with better penetration characteristics allows for better tie-in at the root and sides.
