    I have a TecTig 222 AC/DC tig welder which is a dual voltage machine but which is currently set up for 400v 3 phase and I want to know how to set it up for 220V 32A supply that I have in my new workshop. I cannot find the manual and would welcome any advice as to how to do this (and also a copy of the instructions is there are any out there).

    Or just give them a call and ask for Les.
    They are very helpful.

    Usually there is a switch on the back but it will have the knob removed so you will need to turn it with a screwdriver (and the power off) No wiring changes should be needed. That was certainly the way my 251 Tig and my Opticut plasma were changed over. They are actually just 2 phase when used on 415V and when on 240v a single phase and neutral.

    Thanks for the replies - been emailing Les at TecArc and it seems that my machine built in 2010 is only a 400V machine although the label on the machine shows 400V 20amp and 230V 32amp in the supply box. I must have mis-understood the label when I bought the machine or it was a mistake as it cannot be changed / converted. Ho Hum.....I need to be more diligent next time I buy a machine.

    my miller is similar I took the 3 phase plug off and just taped up one of the extra wires and wired it to a 16amp plug as per the instructions
