Hi guys I am tig-welding som rectangular tubes together in angels, but very often the material tend to shrink around the weld due to the heat so the angel is no longer correct and I will have to pull it in place. The dimensions of the material is 1.2mm and i usually have the amps on 38A and do not always supply ekstra material. What am I doing wrong, how do I prevent the material from bending way too much.
Regards, Peter Anskjær
