It's big, it's blue.. it's a 252!

What wire was it that you were selling for $55, for future reference.

Ill grab a pic for you.

I know mine is definitely not a Bernard. It has an open back where the whip goes into it. Its just like the one on my 130xp only bigger. Nothing like the Bernard Q guns we had at work.

Bernard is part of ITW like Miller.. I wonder if there is some weird branding going on there? I always thought the stock guns on the smaller machines were branded Miller, ie: M-25? Bernards are stock on the larger, heavy duty machines like the feeders I think

Miller is bundling the Bernard guns with some of their welders. I just traded my Passport which had an M10 gun for a Multimatic 200 that comes standard with a Bernard Q150. Nice upgrade. Wish it used the same consumables.

Do you plan on doing any spray transfer welding with your new machine?

I only have C25.

 

[Shield Arc]

If you ever decide to, if I read the spec sheet correctly on your machine it will only put out 28-volts. I've only used C/10 and I had to go up to 29-volts. You may want to try an argon oxygen mix, like 99% argon & 1% oxygen, or 98% argon & 2% oxygen. I understand with the oxygen mix you can hit spray transfer with lower volts.

The wire that was $55 was Uni-Braze. They sold lots of it. It's made in China but for $15 a roll cheaper, it works just as good.

Personally I don't think spray is worth all the trouble for the home shop. The metal has to be really clean! It is hard on the equipment! After running just a few beads the contact tip on my 200-amp Mig gun was so soft I could bend it with my hand no problem.:shocked:

Yes but it is fast and IMO beautiful. I only used it in a demo but was mighty impressed.

 

[Shield Arc]

She is fast! I'd like to see a side by side comparison in a 40-hour work week with dual shield. I always liked the look of dual shield.

Spray transfer bead is so smooth and uniform. I imagine a lot of robotic systems use it which may explain why some products have such perfect welds.

I've never tried dual shield but wouldn't that leave slag?

 

[Shield Arc]

Oh yeah it leaves a real heavy slag! But I always thought dual shield was very fast. I'd have to go and compare the deposit rates between spray, and dual shield, I'm sure spray will have a higher rate. But where I was going with the side by side comparison is all the extra prep work that spray requires. As we all know, there is more to welding that just pulling the trigger!

Here is a picture of the slag, and a chipped weld.

Yes, prep time would be an issue especially with painted or rusty metal. For some reason I just don't think of spray transfer as something that would be done in the field or outside a well equipped shop. I don't see it being used on rusty old metal but rather on new fabrication with steel that just needs scale removed. I haven't ever used dual shield but cannot quite see that as a technique to use in the field either given the gas requirement. That said, your picture of the dual shield weldment looks very nice....but not as nice as what even I could do with spray transfer! Spray transfer is so pretty and smooth. Looks like beautifully applied caulking. I may be overly impressed with the finish look as most of my welds are still on the bird poop side of the spectrum.

I was the project superintendent on this outfall project. We had a crew of welders welding these 10-feet diameter 1-inch wall pipe with dual shield. 100% X-ray. Had to have the welders in a tent because of the gas coverage.

 

[Mark @ Everlast]

I've never had any issue with my ESAB spray arcing and it's only 280 amps or so max. Not sure what max voltage out is. I use c-18. I'm pretty sure the Miller will do it, if the Everlast MTS 250S will.

And there you have it, proof is in the pudding. Some cool projects you have been on bud!

 

[Shield Arc]

Yeah lots of projects. If I would have known about this Internet thing, I would have taken more pictures. :laughing:

I know bud, I never took pics of anything and never even liked computers. Wasnt my thing till I joined TBN, then it opened me up to some great people and some reliable info! And some bung holes, which also help as a tension release for me, so even they serve a purpose! LOL!

 

[Stimw]

I love not only the look but the sound of Spray Welding! It sounds like you are TIG welding.
My Miller MM210 will just barely do Spray Welding using Stargon gas. It really does super heat the cone and tip though.

 

[jim_wilson]

Awesome. I'm thinking seriously of getting a 252 also. I've got a number of projects that I want to attempt, the old HTP Mig 160 has crapped out - and the small TIG I have (Miller EconoTig) -just won't do really thick stuff.

I'm hoping to get one in the next month or two if all goes well.
