Re: Well I finally got to use my new welder,,,,
One thing that can help is changing the filler wire you choose. ER70 I’m exhaust applications becomes pretty brittle. Experiment with 312 even if it’s carbon-carbon. 312 is more ductile and less prone to cracking. And above all else, clean the ever-loving bejeezus out of the area inside and out. Con...

Re: new to tig stainless
Don’t do a second pass. If the weld is fully penetrated through to the inside, you’re perfectly fine for strength. Stainless welds are very, very strong. I have made lots of stainless headers, mid-pipes, even welded up the exhaust manifolds and up/Y pipe on my diesel and never used filler. They are ...

Re: New guy saying hi.
When I weld sheet that is that thin, I place a tack about 1/2” from the end. Then as I weld to the end, the tack allows me to pick up some “extra” material and I know to begin backing down on my amps. An extra dab of filler at the end with a progressive pedal tapering seems to work for me. Realize t...

Re: New guy saying hi.
It’s important (when possible) to get a look at the backside. The amount of penetration will tell you volumes about heat, filler and travel speed.
Those welds do look over-filled. Using a bit less of the filler per dab might be all you need to do.

Re: Everlast 255 EXT magic smoke escaped!
Take a look also at the new PrimeWeld 325 with a water cooler on Weldmonger’s store. For the money, jeez, they’re almost free. And the 225 has been a very good machine for a buddy of mine for 4 years without a hiccup. (If the worse comes to pass and you have to buy a new unit).

Aluminum looks really good. I chopped up the rest of the stainless tube to practice going around a tube with a curve to hone my stops and re-starts.

Re: Spray welding question adapter needed
You bought a cheap rig and want pro safety features? Put down the crack pipe and spend some money on things that actually make you money.
Or get to work cobbling together a solution.

Re: Spray welding question adapter needed
If the OD is 12mm, then the threads are not TPI, they will also be MM. measure the distance between the threads, that’s the pitch. Standard 12mm threads are usually 1.75, fine is 1.50, super fine is 1.0. If the OD is ~0.470 then it’s definitely 12mm (0.472).

Re: Why might Jumbo gas lenses be preferred for pipe or tube?
Jumbo lenses are preferred by pipeliners as they are easier to use when walking the cup. More than not, they have wide open access to the joint so the stubby isn’t needed. The bulkier cup lays better while allowing you to maintain the arc angle when walking the cup. Even for welding sanitary, a #8 i...

Hi CJ, There's not really a way to use a backing plate to weld the whole cube when it is bent into shape. I will take a pic or two later and post here so that it makes more sense. Thanks, Jeff I can certainly understand if you're welding outside corners of a cube. In that case, larger diameter fill...

Re: Holding Stainless Steel for Fit-Up
Is there any means of using an aluminum backer piece? That will not weld to your stainless and can serve as a support for the bridging tack.

Re: New guy saying hi.
The only glaring thing is the restart. You need to back up to the prior last bead, start there and get it wet, then add filler there and move forward.

Re: New guy saying hi.
33 amps might be a little low for 16ga. When the amps are too low, you have to wait in the stainless to melt, that causes a lot of heat input. As odd as it sounds, a touch more heat gets your puddle faster so you can weld without introducing as much heat overall. Of course, the higher the amps, the ...

Re: Spray welding question
Whether you spray weld or TIG weld it, it needs to be machined afterwards to turn the diameter back to spec. For spray welding, you need to be 100% certain of the base metal and application as not all powders are appropriate for all metals.

Re: New guy saying hi.
With 1/16 filler on 1/8 material, I’d be closer to 95 amps to avoid the base material absorbing so much heat. That’s why your beads are turning blue/purple after a bit. Also, with only a #10 cup, make sure you’re using about 20cfh or gas. Your practice looks really good. Nice and even stepping. Bump...

Re: Will a better welder help me achieve better looking welds?
I would also add that your buddy very likely has his Esab tuned just about perfect. Drive roll tension, spool tension are factors often overlooked when MIG welding. The consistency of the filler coming off the roll has a significant bearing in the appearance of welds. If it sticks and stutters, you ...

Re: Looking for a new 'budget' MIG or MP machine.
If you opt for a PrimeWeld box, I encourage you to NOT buy the 285. Yes, it is a multi process box, but it will not run 6010 rods. And from your posts you don’t need a multiprocess box. Being restricted to lift arc DC TIG is pretty aggravating if you get into TIG work. I’d buy their separate TIG box...

Re: Looking for a new 'budget' MIG or MP machine.
I don’t know anyone who would characterize an Everlasting as “bullet proof”. Mostly they call them “Neverlast” due to reliability issues. Esab is an excellent machine, as are HTP. Don’t discard the PrimeWeld boxes. They are surprisingly good machines and are very inexpensive (not cheap). You can buy...

To start a Stick, you "lightly scratch" the rod along the surface. This requires a LOT of practice to develop the right "touch". A trick you can use, is to touch the side of the rod along the edge end of the practice material, then drag the rod along that edge until the end of th...
