Is this any good?

A question for you welders.

I have a stick welder. I wanted to weld some holes on the steel corrugated roof on my shed but I think the stick welder was too powerful and it blasted an even bigger hole.

Would this be a better option at its lower setting?

I was shite at welding, I tried to repair a mower deck and when I had finished it looked like an AR 15 had emptied its mag into it. I think the setting is too high for the metal density when it blows holes. I am still shite at it.

I have a few holes in the roof which leak. I tried to patch them up with some bitumen tape stuff I have but it still leaks. I could try and get another sheet to put over it but it would have to be the same profile and I've no idea how to measure it up. I'll try and weld it instead.

I would epoxy glue fix patches cut from a Coke can over the holes. The thin alloy is malleable and easy to bend to fit the profile.

My take on this:

No chance of welding something that thin with a stick welder.

Would take a good welder (person) to get something that thin waterproof with a mig welder.

An inverter wire fed welder (as you linked) is supposed to be a step up from a traditional mig welder however a flux cored mig / inverter would be a step down but I have no personal experience with a flux cored or inverter welder.

Lidl do a tig welder. A tig welder should be the best bet for welding something that thin, but again I have no personal experience and they're more £ and not in Lidl right now.

Any welding is going to rust fast and you'd soon be back where you started. Maybe you could use galvanising spray on inside and outside when you're done?

Best bet would probably be a screw with rubber washer and maybe some sort of sealant if it's a small hole or, like DWD suggests a piece of coke can 'glued on' but I'd go with mastic or car windscreen adhesive over epoxy.

For all the options like for decorating the preparation is more important than what you use and how you use it so clean the area off with a wire wheel then if using any type of mastic or glue with a solvent would be the first steps.
