Thank you so much don! I appreciate you watching and happy to help 🪙

@@PacificArcTigWelding hi there, hopefully you can advise me . What Tig welding material do I need to get , to weld an automotive gearbox , do they have more magnesium than alloy or visa versa... I've tried just pure alloy but it won't take .. thanks in advance.

Thank you so much for watching Andy, I appreciate you very much🙏

Thank you so much for watching, I appreciate it🙏

@@PacificArcTigWelding Absolutely, I think your form of artwork is stunning... I wish I were able to afford a piece for my wall... It would be the center piece for sure... So thank you for what you do...

Every day is a school day.

If you mean thickness, then you turn the head to thick part, preheat it and manipulate the puddle to flow into the thinner part. Molten weld puddle is a liquid and it behaves like one, think surface tension - You jiggle the head and puddles will fuse. "Cold shoe" on thin part would also help, by taking away much heat, so the thin part would behave closer to the thick. Using cold shoes all the time welding copper, about 1/2" or 12mm to each side of the seam, keeps heat softened area much narrower. I have learned to weld with the flame welder, decades ago, mostly copper, some Aluminum, then analog transformer TIG, and finally new digital. Old was good for copper, but the new one just kills it on aluminum, because now you can regulate the amount of heat going to seam and up to electrode, to clean Al oxide instantly forming on seam. Just go new Chrystal 2 helmet, as the name says it's almost completely clear. Need to learn not to lift it up anymore. If you are a serious welder, give it a try. Paid 370€ or around 400$. If you're beginner, keep focus on your shoulders, as you will tend to raise them, to "lock" the position. I got some serious cramps at the back when starting. Now, when I teach, I stand behind the apprentice and hit his shoulders down. Takes a while, but fatigue is much less. Still, I do not claim to be THE welder, because there is still a lot a don't know. They get paid well, but it's a HARD earned money. I do know several trades well enough: manual lathe, mill, press brake, manual spinning, tin work, copper forming, custom jig, machines, tools and process design......Just bought GoPro, gonna make video on making the wood mandrel and spin copper on it.

The biggest filler I keep in stock is 3/32" except for aluminum, all other filler is in smaller diameters. I have already cut some .028 off of my wire feed welder to use for TIG. 70S-6 wire is 70S-6

I'm fairly new to welding but I haven't been able to tell a difference between different tungsten diameters, what's the benefit of using a skinnier tungsten?

@@NNFaNRacing The first benefit is smaller tungsten requires less start amperage, useful for thinner metal so as to not blow holes during arc start. Second is, tungsten glows orange hot and radiates that heat. Smaller tungsten equals less collateral heat transfer that is not arc specific heat. Also, the torch and cup stays cooler longer, you can wear thinner gloves, etc. I always use the smallest tungsten that can handle the required amperage for the weld. I work in an aluminum and stainless fab and weld shop and use strictly Diamond Ground Products Tri-Mix tungsten with the turquoise band for everything. I use 1/16, 3/32, 1/8, and 5/32. With each diameter, I found the max amperage by turning up the A/C amps until I see the end of the tungsten begin to wobble and distort, then record that amp number for that welder. Inverter machines will put more amperage down before tungsten wobble than transformer machines. Example: Lincoln Precision Tig 375 transformer will wobble a 5/32 at about 260 amp. Everlast EXT 350 inverter is closer to 290 amp. Tarheel Alumunum. Facebook or online.

Thank you so much 🙏I appreciate you watching🪙

update- its extremely difficult. I was using mild steel and seems like it wanted 60 amps before it would even tack. Then wide open at 48 amps it was still barely melting the metal. Not sure why

@@michaelriccardi424 maybe try tighter arc length. Just a small variation in the arc length can make a huge difference in the heat input on thin metal.

Yup, completely agree with you. Obviously this guy has not learned any theory about tig welding. To get a smaller weld you need a smaller tungsten(depending on amps), tungsten sharpening angle need to be close to 90degrees(this creates the tightest puddle with greatest penetration), and the most important your arc lenght has to decrease(to about .5 to 1mm). More proof that this guy doesnt know what he is talking about, is that he this there needs to be penetration in a T-type joint(this is wrong there should not be any weld on the other side of the t-joint, it only decreases the weld strenght). About shielding, this guy never does it. He had a video about welding titanium where he knew that it had to be welded in a 100% argon atmosphere, how ever he still did not provide that. and the result weld had cracks all over it and he just ignored it.

Yes it is he sugared his back he burnt through lay wire with pulse

I noticed myself melting 1/16 filler with the arc when welding 16 gauge stainless pie cuts around 47 amps. Or I have to use too much heat to get the pass made, which ends up in a big bead. Then needing 15 seconds or more of post flow which is absurd. I think I need .045 filler and should be running around 38 amps

@@michaelriccardi424 it depends how fast you can weld. In your case, I would definitely prefer .045 wire. (I buy 1 lb mig rolls because they are cheaper) You will probably need 42-45 amps.

@@russellmclaughlin8526 I twisted together some .023 stainless mig wire to make .046 and as soon as i dipped it, the filler popped real hard and flew out of my hand. I think it would of shocked me if I had no gloves. Not sure why that happened.

Defiant Metal actually! Absolutely love them. I appreciate you watching 🔥

Depends on the thickness and metal. Sanitary stainless is done without filler. I can do a decent job on 20 ga stainless on an outside corner joint without filler. I think it also depends on the joint type. Not as good on a lap joint without filler, at least I am not.

@@silentpoet75 Thanks for the reply and information. I appreciate it!
