Hi All,
I have just bought a DC inverter welder. It runs up to 100Amps DC from or local 220-240V AC domestic supply.
I'm trying to come to grips with what type of electrodes, what current to use etc.
I've watched a few Youtube videos and have done some online reading and it seems to me that DC Amps are the same as AC amps and that, for welding about 3 or 4mm steel I need to use about 80-85 amps. I've worked out that multiplying the thickness of the metal in mm by 20 seems about right to estimate amps (eg. 4mm x 20 = 80amps). We don't work in imperial measurements so "thousandths of an inch" is a bit cumbersome for me!
I'm using 6013 type 2.5mm diameter rods.
Does this sound about right?
Would appreciate some advice.
Sorry if I've missed any "howto's" etc. there is soooo much to read its hard to find what you're looking for1
Cheers!

I guess no one has experience with those.
Not sure what machine you have to make a specific suggestion but in general if you have a lower capacity unit, the smaller the electrode, the more stable the arc and longer you can weld.
What exactly is the make and model of your welder?
