Since you already have 220V ,well thats half the battle.
Ive taught alot of apprentices as well as Journeymen to weld. I cannot recommend any Youtube videos as Ive never seen any on welding but heres a few pointers.
Your welding rig should have a small welding chart that will give you the Settings for the material your going to weld. Set the machine dials to what it tells you,all rigs are different and will react different. Once you get used to your machine you wont need a Chart
The Standard rod is "7018",they sell it by the pound and it comes in different thickness, buy as much as you can afford as well as scrap metal to practice. You determine the rod thickness by the material thickness your going to weld. 1/8th is a good start. The ONLY way your going to get good at stick welding is by burning rod,over and over and over again. Try to get metal at least 3/8 to 1/2 thick anything else and you will bend and warp it with the heat.
Dont spend $300 on a fancy auto darkening Hood, instead get a regular
#10 shade to start, and you MUST get a welding jacket ,a cap ,and good gloves that are not too stiff. Cheappo gloves are horrible and you wont be able to "feel" .A chipping hammer and a wire brush along with a grinder that has a wire wheel and a grinding disc are needed. Stick welding produces alot of splatter when your new to it, Dont go Macho and weld in a t-shirt,you'll be sorry,Trust me I know .
When you get comfortable ,Your first Real project should be a welding table as any welding on a wooden table top will make it go up in flames. I Always wear ear plugs as I personally know 2 coworkers that got splatter in their ears and needed surgery. If you have never welding before, be forewarned ,your going to get burnt. Stick welding is hotter than hell.
If you have any questions P.M. me I'll be glad to help you out .
