GIANT WSE 200 amp ac dc tig welder

is the tig welder 120 or 240. If 120 no you can't

Your question is not clear, but if it is, your welder should have an handle to switch from dc+to dc- and ac, it wont do it on its own

Go to this site and you can download or print a manual for your welder copy and paste to google search engine and it has the manual on pdf. TRANSTIG 200 AC/DC Servic Manual - Victor Technologies

switch from tig welding to mig by switching your current from AC to DC for mig. change from your tig gun to your mig gun. turn water flow off. proper ground and weld away.

no chance

DC current, electrode negative (DC Straight, DC-), High frequency for start only (really don't have to use high freq at all for steel but it helps establish the arc without scratching), 1 amp per thousandth of material thickness is a good setting to start, adjust from there for the job. 1 amp/thousandth also applies to aluminum- it has a lower melting point than steel but conducts heat much better so power to weld is very nearly the same.

Use a sharp tungsten, don't ball it at all (as you would for AC work).

i have a old miller thunderbolt CC*AC/DC welder its wire single phase 480 can it be switched to 220 single phase

check if the load on it is not more than its capacity and check the batteries if they are still in good condition

Hi, remove the machines cover with the machine unplugged then look for disconencted plugs etc within the machine. careful where you place your bare hands.
