Get in car, drive to see Richard
This will make life worse because it will slow him down and increase heat input.If you're struggling try a 2.4 filler it will chill the weld more than a 1.6
Will do.....This will make life worse because it will slow him down and increase heat input.
@Noods 90-100 amps is fine for a lump of 3mm plate sat on a bench but too hot for for an unbacked joint on tube. Yes I probably could weld it at those currents but you want to be more in the region of 60-75 I’d say. Arc length super tight is the trick. Put some plate pics up noods cos that’s where it’s gotta start. We don’t move onto tube until plate is like second nature
But if he's practising it won't matter it's what I did when learningThis will make life worse because it will slow him down and increase heat input.

Will do ...Still way too hot, you're destroying the material, you want be knocking at least 10/20 amps off. Turn the juice down until it is only just melting the surface of the material then practice laying runs down with no filler until you are able to keep everything consistent, long, long way off tackling pipe joints. By the look of those crater pipes in your finishes you need to whack your downslope timer up as well
I think it will make it harder for him. A 2.4 rod will stick quite badly into a 75 amp pool. The only way it works on current less than 150 amps is with the lay wire technique or open rootBut if he's practising it won't matter it's what I did when learning
Did you do the top one first, the ones below look as if the plate is pre heated from previous welds and that's why they've sunk, allow the plate to cool down between runs but they are looking loads better with no crater pipes. Once you've got the hang of this start adding wire, you may need to turn the juice up 5 amps or so to compensate for the cooling effect of the filler wirePost flow now 3.5 ditched the foot pedal amps now at 35amps with tight arc.. these beads are no filler rod...

That's looking a lot better
