picked up a Castotig 3002 locally and thought id have a go on some thin ally sheet first attempt was pretty dire and using a filler rod very quickly second attempt seems much better starting to get used to it a bit more adding less filler and speeding up a bit also getting used to lift start as hf doesnt seem to be working not sure whats happening at the end of the weld initialy I was lifting the torch away as soon as i finished but am leaving it threre for a few seconnds now also on my first attempt I was starting before the weld pool had formed.
