In the meantime, go through the basics, just to see if you are missing that one basic step. What do you have to lose? Sometimes we all miss little details when we focus on the big picture.

Were you doing Mig, or flux core? Never tried it yet, always assumed it was an overpriced spray that "kinda" worked.

Not quite sure yet, but I will bet it's operator error. I have the PowerUltra205 (older model), 1/4" is a breeze for the plasma. I can do 3/4". Make sure your tip is good, air pressure (too much is bad) is good. clean, DRY air. Good ground, proper angle, speed, etc............. go over the...

Chop saw is faster, noisier, messier, band saw, you can do other stuff while it's cutting. Chop saw can do bigger, band saw is way more accurate. Go figure, guess you need to have both, LOL

Yeah, aluminum needs straight Argon. Steel needs 75/25, etc, for best quality. You get a taller bead, less penetration, more undercut with Argon.Don't know about S/S.

Don't do it. I tried it, not good. All the pros also say don't do it.

Yup, same question multiple forums. I either Tig, Mig, or Fluxcore, haven't stick welded in at least 30+yrs. Anyway, been messing with some 6011, noticed no real slag on the welds. Even opened up a fresh, sealed box cause the first few I tried were old, and laying on the bench in the open. Normal fo...

I had a piece of Al, did the same thing. Madee kind of a splint on the back side and epoxied it in. Def gave more strength to the repair.

I would want to repair a keepsake as best as possible. Problem is, if you try and Tig it, and it melts it away, you are screwed. Best bet would be JB weld, or any name brand epoxy. My two cents.

just started to watch the video, what's the deal with scribing with a tungsten, using air to snap it? Can it be some kind of real, or is he just messing with us, LOL?

No such thing. Too short, yes. Too long, can’t happen. Argon post flow provides two purposes: shielding the weld while it cools and cooling the tungsten to prevent contamination from the atmosphere. At 325 amps, 25 seconds is just about right. But your picture shows a tungsten that looks whacked. Th...

Try changing the balance. Wow, 25 seconds is a really too long post flow

Unless you really need the money, or not enough space, don't sell it. Almost guaranteed the day after you sell it, you find you need it.

Unless I missed it in your post, what is the brand/model, maybe someone else here has the same machine, and might have more info.

As you said, hard to picture the wiring, any chance of posting pics of both configurations?

I've been DC tacking aluminum now for close to 15 year now with A75. I thought if you could weld aluminum you knew this trick. But apparently my night guys have never seen it and are questioning my methods. Every site I've been on says it's the preferred way to tack. Is there anything in AWS D1.1 t...

just looked online, looks like some HDs do sell it. Go figure. $204.00 for a 40cf tank, but it also says contents sold separately, dunno. But, ya never know with the big box stores, they like to get a piece of the action when they can.

Sad to say though, at the end of the day, my beautiful S/S headers and sidepipes get all colored up from engine heat anyway. Some color can be polished off, but worrying about weld colors when engine heat gives straw colors, etc...............constant struggle to try and keep them branny new looking.

Hello all, this isn't a question about welding, but about why in freezing weather, does all the power cords to my power tools and welder get stiff. my workshop is in a unheated garage, and every winter time before I can do any work, I have to loosen up the cords. does anyone know the answer to this...

Pricey, but Lincoln welding, www.JFLF.org has coupons for sale, at that address, "project kits" at the top of the page.

Hello all, recently purchased a auto darkening helmet on ebay. the batteries are chargeble by sunlight and also while welding. today was doing a little welding for a few secs. and I was seeing spots. the helmet was sitting in my garage for several days and it has been cold. would this be enough to ...

Guess it really doesn't really matter now, you had to turn down the job, but in the future, do you have a MIG/spool gun available? I'd prefer that over TIG for that size material, and that type job.

I'ved used pedestal, bench, angle grinder, successfully, but as everyone will tell you, don't break the tungsten, it will splinter.

I agree with others, skip the magnets. Even welding magnets messed with my arc, I'd imagine a rare earth magnet is even worse. The welding magnet being within an inch or two messed up the weld, so a rare earth magnet could affect the weld in a larger area?

I found that putting a cheater lens in my helmet made a world of difference, just another concession us old farts need to deal with.
