I've got to weld some 3/16" thick flanges to some 22 gauge pipe - it's a butt weld.


I'm using a Hobart handler 125 flux cored mig welder.

I assume I'm gonna have to zig zag and dwell on the 3/16 - and also position it so my welds will want to undercut the 3/16 and not the pipe.


But my prob is I'm afraid that .035 wire will burn through the pipe - however if I use .030 or less it won't penetrate the 3/16" flanges

any tips?
