Most mfgrs. produce an A C machine which just reduces the amperage. They are cheaper than a D C machine where the electricity has to be changed from alternating current to direct current.
Depends on a lot of things. Slickest work, but most expensive - TIG. Cheapest - arc (stick) welder. Reasonably user friendly and inexpensive - wire-feed arc/ MIG welder.) Most versatile - Oxyacetylene. Oxy will give have the biggest heat affected zone and is the hardest to use (IMO). If your kart is really thin wall tubing you can forget about the stick welder and even the MIG will be quite tricky.
Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It's used for welding thicker metals of 1/16 inch or greater.
a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas
sure but it will probably take longer than if you use a wire feed. you might have to cut the rod in half to get to tight places. and a stick welder might be to hot and burn through the pipe you use for roll bar
There is no cheap way to earn a welding certificate. You can see if a welder is willing to take you on as an aprentice.
Tig, mig , or If you are as good as me stick welding will all work

Pipe welder?
I don't see why not. If you can see well enough to use the equipment or handle OFC and Stick/MIG/TIG then you should be fine.
Mig (GMAW) has almost replaced Stick (SMAW) in industry. Small machines can weld thin materials and larger machines weld metals of unlimited thickness. Mig is easy to use and has less waste (no stubs) than stick. Flux core wire produces a slag covering but bare wire w/gas leaves a clean weld.
No , although Co2 may be used , along with other gasses , a welder using this process is not considered a Co2 welder . TIG stands for tungsten Inert Gas , so the welder is considered / called a TIG Welder.
The farberware 9-inch cake round cake pan is the cheapest one. You can purchase this pan online for $6.95.
