Through trial and error, I discovered that a previous porosity problem seemed to be caused by my too fast travel speed, using 0.9mm flux cored wire on a 4mm practice piece of mild steel.
Having removed the mill scale, I did a lap weld at 3 different settings on my Parkside PIFDS 120 B2 inverter welder. The current control knob is marked in millimetres of material thickness, running from just below 0.8mm and up to 3mm. That equates to between 20 Amps and 120 Amps.
In the images below, going from left to the right, is 2mm, then 2.5mm and lastly 3mm on the control dial. I'm left handed, so everything was welded right to left.
My question is, am I doing something obviously wrong, as the top of the weld sticks proud above the top piece of steel?
I think at the ends of each weld, I lingered too long, cutting into the top piece too much.
