help with stick welding

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?

A few tips from Spain... NEW

Before buying an inverter think twice what other features you may need (or may want) in the near future. Do you plan on doing some TIG as well?
If you want it all and want to TIG aluminum... you will need to take a big step and go for a dedicated AC/DC inverter that will also serve you well for stick welding.

Also think if you plan on burning celulosic rods. 6010 and 6011 are not so common on this side of the pond but you may get tempted reading US forums and such, it happened to me and now I am the proud owner of 12kg of 6010 that will last for a lifetime XD XD. Most of the inverters, unless otherwise stated, don't go along well with that kind of rods.

With those things in mind start looking for something that suits you. If I were on the market for another inverter, I will look only into the 200amp range machines. There is plenty of 160amp cheap imports out there but they won't cut it if you plan on doing heavy stuff (and 10mm single pass is heavy stuff by my standars).

Good luck!
