could somebody help me please i'm thinking of buying an inverter and would like to know how many amps are needed to weld 10mm mild steel and what size rod to use so that i can do it in one run? any info would be very helpfull. thanks.

jody here...

amps required is more according to rod diameter.

10mm in one pass is pushing the limits of a stick rod....

you would need about 250 amps and about a 1/4" or 6mm rod.

If the welding is all to be done in flat or horizontal, a 1/8" 7024 rod will run a very smooth bead on dcep and a 200 amp machine set at around 160 amps would lay a big hot bead.

anyone else got some suggestions?
