Good advice, I burned the logo on my t-shirt onto my chest onceLike to add my little bit here,
Mig is by far the easiest to use, it will do just about any metal work job you need for use at home..
Tig welding is for me very satisfying, you get the finish of half circles that look very neat.
Arc (stick) welding takes some getting used to as beginners find the rod sticks as they have not learnt 'how to'.
All welding gives you a sense of achievement, you have joined to pieces of metal together for good.
Thickness does not mean much to me as i had years of plate welding, up to 4in (100mm) thick but 3/4 and 1inch were the norm along with stainless, Ali, Copper. All of that was positional as well as we made furnaces for melting steel that weighed up to 25 tons.
I still like welding to this day.
Always wear as darker shield as you can. If you do Ali tig welding be careful of extreme sun burn.
Long picks are good if you want to strengthen or tidy the edge of a weld.what are the masonry nails for?
To give an idea, a boilermaker who recently did some work for me used and an ancient 180A gas-less MIG. You may be aware that boilermakers especially having been approved with X-Ray are the cream of welders.Getting the current spot-on is a great part of good welding however penetration and width of weld are what gives the strength.
