I've been using the Lidl rods that I bought when I got the 80amp inverter, but bought a few Fincord M rods and tried them tonight, in comparison to the Lidl ones. First pic is the Fincord 4 lines on the left, Lidl 4 lines on right. Both rods 2.5mm E6013, at 80 amps. Next pic is my very poor prototype of my sons birthday present. This needs a clean up and hopefully mark 2 will be a fair bit tidier. Wish I'd taken up welding years ago.
