2In addition to Tyler's final question above, is there a specific welding rig that would be ok for home use, say, to do stuff like ldopa's record cart's metal frame that was posted in the woodworking thread?Also, this forum fucking rules, doesn't it?

3Years ago I did some wire welding robot work for the shop that this guy apprentices at. They would do mold repair and medical welding. The shop itself was a weird mix of non intentional blade runner-esque mess and high technology. The welding however, was crazy https://www.instagram.com/marcweld/?hl=enI like this thread. I used to work alongside Lincoln Welding automation group, so I've had to use a lot of the theory, but I'm on a practical level completely useless at welding. Right now I have access to a mig and tig setup at work.If you had to pick one to start on.. tig?

I'm imagining something like:- Check for puddles in the shop- Make sure your work is grounded- Cut & fit everything you might need to get your welding done in one sitting- make sure you have everything within reach.- stretch

MIGS are also useful but i find that beginners spend too uch time 'dealing with the machine' than welding and its easy to get frustrated and give up. a stick is versatile enough to weld steel , stainless and bronze. most of the welding you'll need to do is mild steel, and a stick welder is an affordable and totally useful thing to have. you can go through tons of sticks while learning and there are no moving parts to piss you off while youre getting the feel. the other huge part of welding is cutting and fitting, which are of the utmost importance as well as ventilation, common sense and safety gear. an idiot welds with a t shirt on.Most of the stuff on that instagram is hand welded - super crazy. That's all good advice, thanks!

8Great table, and the size/power requirements/cost of that welder is totally reasonable

10I'm just about to start learning to weld (at work), so you'll excuse my idiotic questions!'Gas-less' MIG is different from 'stick' how? Don't both use flux-core? Is 'gas-less' MIG used to describe the self-feeding wire welders, as opposed to stick?Sorry!
