Do not underestimate how fast you can start a fire, I am looking at the cardboard in the garage pic, with the helmet down you will not see things on fire around you. I mostly do TIG now a little safer in a garage, any STICK or MIG I do in the driveway. And keep an eye on the area you were working for at least 30min after finishing.

Thanks...add gambler sleeves in leather from elbows to wrists...Ask me how I know.

MIG welding is the usual choice in this area because wire-feed welding is easy to learn and can often be self-taught. Just pull the trigger on the welding gun and the wire will spin out from a continuous feed. At the same time, a shielding gas will protect the metal from environmental impurities, creating a clean bead very consistently.
