I have a Lincoln AC225 welder (with add on DC).
I would like to make plug welds in 1/2" bar stock. I experimented
recently with welding 1/2" thick plate. I started with a 1/4" hole
and moved up to 1/2" holes . 1/2" was almost too small. I am using
3/32" 6013 DC+. I would make a mulitple welds (about 3) chip out the
slag between the welds and reweld. Without chipping there would be
heavy slag in the weld.
Is there any general rules or techniques to follow?
Would 6011 be a better choice?
