Help please
Iam in process of some fabrication work in spain
Iam using a 160 amp cevic welder
2 mm rods
1.5 galvanised box section
Now the problem Iam having is trying to weld one piece of box onto another
I have tried grinding it/ wiping it/ low amps/ high amps/ different angles of the rod
But what happens is it welds either piece of metal but leaves a gap in the middle
It's driving nuts
Any advice would be really welcome
Thankyou in advance
Ps I can't work out how to upload pictures
