Hey guys, The big brown truck dropped off a new 255 EXT this morning and finally got to run a few beads. First four beads on 1/8 plate. Top to bottom: #1 no filler; #2-#4 1/16 4043, 80 amps, 120 hz, 30% clean, 15 CFH. Be critical guys, I know the first one washed the edge a bit, and the last one on the right I think I went to fast bead is really flat.
Actually they look pretty darn good for first welds.
Things to bear in mind:
Ally soaks up a lot of heat while running stringers. Let it cool or quench it for practice.
Travel speed and filler consistency come with practice. These two things also contribute to even bead spacing and size.
I like to take a flat piece, scribe two parallel lines about 1/8” wide or so, then run stringers between them. I add filler until the puddle grows to the lines and sinks in. Helps with getting the puddle control down. You can always push the puddle ahead to move filler if you over fill. And watch the edges to makes sure you’re getting the puddle to burn in, and not “humping up” due to lack of heat.
