Picture of the broken item would help.

Hence my desire to see a picture of an item.

Thin stuff is real tough to do. Usually you end up with a large weld that you end up grinding off 75% of the weld to get to the finished product.

TIG is better than MIG, but TIG you have to spend considerably more for quality equipment than MIG or you are wasting your time even trying TIG. TIG also demands some practice for those perfect pretty welds, takes longer to master.

Been welding with MIG (Aluminum and steel) for 35 years now, it is pretty easy to pick up with a half way decent welder. I have a Lincoln 110V unit I do most of my steel work with and for what I do works fine.

FYI once you learn welding not only will you be able to fix stuff that normally might get tossed out you have the ability to make tools to make jobs easier, fabricate almost anything you can think of in steel or aluminum and make some tidy money repairing stuff for other people. I'm constantly repairing hospital beds and get paid $75 for 5-10 minutes work.

I run a physical plant department at a nursing facility, the welding repairs are always a welcome extra source of cash for my hobbies. 2 months ago I repaired a bed with a broken deck which normally would have been replaced and saved the facility $1800.

Overweight clientele can wreak havoc on the equipment should they feel cranky.

Beds and dietary equipment make up the bulk of my welding repairs, my boss is appreciative as it saves a considerable amount of money compared to replacing the broken items.

Bed rail replacement runs $300-$400 a pop, $75 is a bargain and stronger than new when I'm done.

That would be a snap to repair with either TIG or MIG.

Quick tap with the gun, 5-10 seconds on a belt sander and you would not even know it was broken.

Just don't.

You will end up frustrated trying to use a cheap welder, when it comes to TIG you go big or go home. Buying a cheap TIG is not the way to go, a $500 110V MIG will however produce reasonable results for that thickness metal.

Here is a fine little rig for MIG welding, pickup an Argon/CD tank from a local shop and start practicing. Take the flux wire and toss it out or throw it in the toolbox for an emergency. Don't be tempted to weld something nice with flux core, it is a splattery mess only fit for exhaust work IMHO.

With TIG a dedicated clean area is not out of the question, its that sensitive.

Tell you what Nic- If we end up making a deal on the pins we discussed I'll toss in my old 110v MIG unit, its been doing nothing but gather dust in the attic storage. It was a little cranky time to time but still working when I purchased the unit I have now and kept it as a backup.
