  • When I was in manufacturing at Rocketdyne many years ago, all of the welds on Rocket engine parts were done with Helium. It was called "Heliarc" then, whicn was a name coined by Russell Meredith of Northrop Aviation ca 1941. Linde later perfected the equipment. The welds that I saw were beautiful...

    I feel better now since I see that a Moderator here who has been here longer than I and who has many more posts only has two bars. That's also a very clever method of giving oneself a full rack of bars. I think I may go to a bar and celebrate now. Thanks Mr. aametalmaster....

    I've got no bars. Every time I get on a website that grades members, it becomes a contest. They should get rid of the bars and just have a website. I was on the older format and it worked just fine without the bars. I notice that the site is much quieter with the new format. I'm also on the Welding...

  • I have extensive experience with cracked aluminum motorcycle parts. With any piece that has had contact with oil, a successful weld will require that the part be disassembled, cleaned and deburred as mentioned above by other posters here. Also, preheat will help. To do it with the crankcases together...

    I make it a point to stay away from both Lava and Harbor Freight welders. In answer to the question, I will say that experience will show through in most cases.

    I have several boxes of Pure Tungsten as well. It can be used on aluminum but the ball that forms on the end will get rather large after a while. It's not the best. As mentioned above, I lke Thoriated and Lanthanated. I haven't tried any of the others, however....

    The only capacitors used on some of the TIG 250 of which I'm aware are the power factor capacitors. While the kit would have been expensive from Lincoln, you could get both of them on eBay for less than $20 apiece. The ones on the two units that I owned were just two metal cans mounted on the left rear...

    Lanthanated is very good on transformer machines. I don't know about inverter machines since I don't own one. I mentioned thoriated because when I bought my first Lincoln Idealarc 250/250 Tig/Stick welder in 1990, the seller gave me a 25 pound box of 3/32" 2% Thoriated. I still have so many of...

    I've owned two of them in the past. 3/32 2% Thoriated or 2% Lanthanated with 15 scfm of argon for nearly everything. If you can get one that is in decent shape, they are an excellent welder and especially good on stick, although not bad on TIG, either.

    Inverter machines are nice, no getting around it. That said. I have seen some marvelous welding done many years ago at Rocketdyne on Transformer machines with helium and straight DC back when they called it Heliarc. (stacks of pennies, nickels and dimes all fhe way) If you are a good welder, an inverter...

    replied to 10 yr old millermatic?
    I'm not sure from reading this thread who it is that is getting a Millermatic 252. Either way, the standard gun that came with my 252 when I bought it new was the Miller M25. It's 15 feet long and works very well. I know that some people like to change to a Bernard or other type. My friend has a 30...
