Welding 'Thicker' Sections

[HasBean]

A passing thought, if I'm welding 6mm plate but from both sides, do I set the voltage as if it were 3mm or 6mm?

Hi,

if your welder can do 6mm why are you welding from both sides?

I didn't word that very well did I
It can only just manage 6mm on a good day when the sun's out (probably closer to 5 at a push really)
Just wondered if I had the volts too high if attacking from both sides really.

Is it a T-Fillet? Or a Butt Weld?

If its a T-Fillet, you should still weld it at the same power you would use as if only welding one side.

If its a Butt and your welding one side and turning it over, back grinding and welding it then you could afford to turn it down slightly.

Thanks very much, that's what I wanted to know.
