A MIG welder Gina, its all in the settings and technique. Look on line for tutorials for welding thin gauge, spot, let it lose red then spot again. Well I spent 2 hrs welding the floor that I had tacked together and other bits, back started to hurt from bending. Managed another hour of making stuff but had to go home and rest before muscle spasmed, I know by now when to stop. Okay this morning after a good sleep.
Food shop day so will get another rest, but then I have 2 bags of shopping to carry up the stairs that will be heavy as sack of potatoes, cauliflower and other veg is not light.
