Miller 255 Pulse MIG

Agree. Pulse is in every ones future. I have a variable twin pulse machine and run pulse for speed and twin for looks. Fun stuff.

I agree 100%.

At the shipyard where I used to work, and now at the shop (I am a welding instructor) we have Miller 350 Inverters, and you can really dial those welders in once you start messing with the programs. They are a little slow for my tastes in regards to vertical-up welds, but there is flux-core for that.

I was thinking about this thread last night as I went to bed, and I think I am certified to weld down in pulse-mode. I am pretty sure I took that weld-test, but it was a long time ago so I would have to check.

For speed I like spray-arcing. You can only do it on the flat, but can you ever pound out the weld-inches doing that.

Just for fun, I was welding a missile silo up one time that took 155 passes to make the fillet weld on the 4 inch thick plate. I had to run (2) guns because they would get too hot to hold after awhile, but I ran 5-1/2 rolls of wire in an 8 hour shift. That was 55 pounds of wire. I cannot remember the exact settings, but it maxed out the welder, and it was a Miller 450 and not the 350. I think it was at, or just over 700 inches a minute on amps, and 27 volts.

We were a Union Shop so the wire cribs would only let you take out (2) rolls of wire per day, so I had to stock-pile it in my locker for a few days to do it, but I really laid down the wire that day.

I would even spray-arc hull seams because it was so much faster. They always passed x-ray so it was a good enough welding process.
