We need to establish what is considered thin metal.
How to weld sheet metal with a arc welder.
That makes this a one handed process.
Every surgeon can operate a scalpel but only a few could work with any tool.
This adds two operations.
While wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead.
Forget the larger 1 8 inch tungsten electrode and use a smaller one.
Removing the coating and re spraying or painting the weld seam after welding to regain corrosion resistance.
To weld sheet metal with solid wires use electrode positive ep or reverse polarity.
There is occasionally splatter from the spread of the arc.
The real trick to weld sheet metal is to use a wire feed.
A wire feed or tig welder is ideal for sheet metal but we will assume that you don t have one.
The heat produced by the short circuit along with a non reactive hence inert gas locally melts the metal and allows them to mix together.
I would compare it to performing plastic surgery with butcher knives.
Disclaimer due to factors beyond the.
For sheet metal i use ine welding wire and it is just as good as their flux cored wire if you want you can grab one here.
A standard arc welder is undoubtedly the best way to weld galvanized steel.
Short bursts or tacks will help.
Mig welding uses an arc of electricity to create a short circuit between a continuously fed anode the wire fed welding gun and a cathode the metal being welded.
As a rule when mig welding sheet metal never use a body filler metal that is thicker than the base metal.
Now you know the secret of arc welding thin metal sheets.
Tig welding sheet metal.

Just kidding this tip is to explain how to weld sheet metal with a stick welder.
If you are new to welding and only have room.
Mig or metal inert gas welding aka gas metal arc welding or gmaw also uses a gas shield and filler material however in this case the filler is a wire fed directly through the welder.
Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal.
So you can keep the other hand free for manipulating your materials and other tools.
Try going for a wire of 023 inches when welding sheet metal.
If you can work outside when using an arc welder.
Arc welding is a versatile method that uses alternating currents to create a high heat arc that melts your flux.
