Hi, I've offered to repair the stair bannister in the reception area at work. As it is a h/safety problem. Basicly its fell apart. It's made of satin stainless tubing i think, held together with small tack welds. I'm not sure which welder to use. Mig or Tig?. I've got both, 100amp ones. I dont want to make it worse than it is and make a tw*t of myself. It would be good practise if i can get it right....... Thanks.
