One is just as safe as the other. The deciding factor here is what supply voltage do you have at your establishment to operate the welder a single phase or three phase service.
Steel is such a commonly used metal that almost any welding machine can accommodate it. Some are better than others though. Steel is usually welded with either sick welding, or wire welding (gas shielded or flux core)
The electrode. In some cases thin materials weld better with DCEN.
it is not a question of which is better. the welding types are chosen according to our own requirements
yes
Well, it CAN. But for the effort and money required you'd be better off buying a charger instead.
A welding rectifier is a m/c which converts A.C. supply to D.C.supply. Rectifiers are used for heavy welding work. An invertor is a welding m/c which converts A.C. supply to D.C.supply and then again converts D.C. to A.C. The wt. of invertor welding m/c is less than a welding transformer.

One word - PRACTICE
Using an electrode positive in welding processes can provide advantages such as better penetration, increased welding speed, and improved control over the welding arc.
By this process all errors to be removed and electricity distribution becomes storng. Rectifier always react all abstraction which law given be Ohms.
MIG welding with flux core wire offers advantages such as higher welding speed, better penetration, and increased portability compared to other welding methods.
Flux core welding gas offers advantages such as increased welding speed, deeper penetration, and better performance in windy conditions compared to other welding techniques.
DCEP supplies about two-thirds of the heat at the end of the rod, which allows more digging action, or penetration, into the base metal. It's what you want to use for thick steel. For thin steel, direct current electrode negative (DCEN) is best.
