Well, I'm going to need a bit more practice as I'd like to make sure that everything is solid around this area where the link rods mount. I've managed to get a decent penetration welding 1mm mild steel to 1.4 mm Zintec. I'll try the other way around, but at least there is potential. It's all a matter of adjusting the timing and releasing of the electrode and therefore the time of exposure to the arc...
