Hello,

I want upgrade to Mig welding,but my workshop is in den of thieves and its dangerous to invest much:)Is it worth-while to buy 1 phase 220V set which usually is cheaper.
What is the main diference between 220V and three phase.

Thanks

Hi Andris, from what i understand 3 Phase is mostly for commercial spaces and industrial tracts. Single phase 220V will be a much more versatile machine. Maybe for your first project with it you can build some sort of cage to lock up your new investment.

What is difference between 220V and 3 Phase?

Short answer: Availabiliy of utility power.

If you have a shop with 3-phase power, you are very fortunate. You can, generally, buy better large tools cheaper (used). If you don't, and you buy 3 phase tools, you have to build or buy a phase converter. I have seen equipment that is 3 phase that uses 190 volts to 800+ volts.

Technically.... 3 phase power involves three hot leads. Single phase power involves one hot lead for 120 volts, and two hot leads for 240 volts.

There is also 2 phase power, about which I know nothing except that it exists.
