Thank you for reading these reviews of our favorite mig welding wire.
Best mig wire for sheet metal.
It s a fairly unknown brand but its wire matches lincoln and miller for wire quality and performance for feed and under the heat.
Holding the tip too far from the surface will cause the wire to have to come out too far to touch the metal.
The main reason to use a smaller diameter wire is that it takes less heat for melting and hence the metal around the weld is not heated to a very great extent.
Copper plated and layer wound.
The most common types of mig wire for welding mild steel are er70s 3 and er70s 6.
You can planish it pretty good or just grind it off.
But which one is best for a particular application.
Another vote for 023 easygrind wire in your mig.
And yes it is easy to grind if you use argon75 25co2.
The majority of the sheet metal welding i ve done was with a 90 amp 110 volt welder.
For thinner gauge sheet metal like 18 or 20 gauge we suggest 023 6mm wire in your mig welder.
These wires are designed to meet minimum tensile strength requirements of 70 000 psi.
The suncoo 140 is made of a heavy duty stainless steel body and painted black to ensure long lasting lifespan.
When the material is 18 gauge and thicker you may be able to use a 030 inch wire.
Keep the stick out short stickout of your mig wire is important when welding any type of metal but especially sheet metal.
But be aware that the 023 is really soft.
It also sits at a much lower price range.
It s recommended to use a 023 or 024 inch wire for most light gauge sheet metal work.
Our top pick is the inefil er70s 6 030 inch on 10 pound spool carbon steel mig solid welding wire.
I have some of the old linde 023 and the new stiffer esab 030.
Mig welding is the preferred method for most automotive bodywork and since sheet metal is the thinnest of metals a large expensive mig unit is usually not required.
To weld mild steel choose an american welding society classification wire such as er70s 6 which has a weld puddle that wets out nicely.
Er70s 3 is typically used on clean oil free and rust free base material.
I use both in my linclone mig and the 030 in my cold wire feeder for tig work.
