Pulsed Mig?

Anyone here have any experience with Pulsed Mig?

IS it the cats pajamas for thin sheet metal?

The Lincoln mig machines with sst work like magic on thin sheet, as long as you remember to hook up the sensor lead...

We have a Miller pulsed Mig machine here at work.
Have never used it for thin steel, but I've used it for Mn bronze, NiAl bronze, and stainless steel.
There are a lot of variables, and it's real easy to get way off track when making adjustments.
The phrase "tuning it to a standstill" comes to mind.

We keep a setup card with settings for various materials.

I hear that you can lower the amount of heat input enough that it might just matter, it's nice for out of position work and improperly cleaned stuff.

I'm looking at plunking down on an Optima pulse mig control on a Miller XMT 350 CC CV.. which apparently isn't as good of a setup as the XMT 350 MPA.

Care to hazard a guess if I will what I did with myself before, or put it on Ebay in a week?

This is the only relevant info I can really find.

"Pulsed MIG Improves Speed and Quality on Sheet Metal

Hollinger never had the need for an advanced Pulsed MIG welder until he began manufacturing oil and gas tanks out of 14- and 18-ga. sheet metal for another bike builder. Hollinger also supplied exhaust systems and c-pans, including some components up to 1/8-in. thick. To increase the speed of production without sacrificing quality, Hollinger turned to Pulsed MIG.

"We were dealing with a lot of light gauge steel and butt joints," he explains. "It was hard to use a standard MIG and control it without burning through the metal and have a bunch of ugly slag or poor sections in the vessel being welded. All of these parts are pressure tested. Using a welder with pulsing capabilities was the only way we were able to make it work."

Hollinger achieved the Pulsed MIG welds he was looking for with the Millermatic 350P. Pulsed MIG puts less heat into the work yet maintains good fusion, fast travel speeds and excellent bead appearance. While Hollinger was not an expert at Pulsed MIG, he quickly familiarized himself with the machine and achieved the results he was looking for.

"It became just like a fast TIG weld," he says. "It allows the metal to cool between the pulse so that we don't burn through, which not only improves the quality and strength but prevents us from having to spend time fixing it.""

Given that, I think I'll give it a go.

I've used pulse mode on our TiG and it does the job for thin stuff that I couldn't do well otherwise. Makes it a lot smoother and very much more controllable.

hee hee, he said butt.

Hey Beavis,

I was off on a tangent with the Miller, but check this out

They basically claim the thing will do it for you

Good luck with the 400V input voltage.

Demo a Lincoln with the new Constant Power, STT, and STT Open Root modes before you decide to buy. The pulsed cycles are better than normal CV MIG but not in the same league as STT and CP from my experience.

Kevin, Transforming up from 200 is straight forward, the unit is probably 10k or so though, so it's moot.

I'll have to look at it.. ESAB also has some sanely priced pulsing migs.

whelp if youse is un-co-nord-ninated-ed maybe youse shouldn't oughtter be welding.....

Can you pull the trigger?

Just assemble in reverse order!

That's a lot to remember John!

Well, since I'm on this wacky exercise, I'll point out this machine:

3 mig torches standard for brazing, steel and aluminum.. plus more!
