Re: Welding Contaminated Aluminum

Couple of suggestions. V grove the Crack on both sides before welding. Drill a hole through the end of each Crack. Looks like maybe you did this. Hardtotellon my phone. Did you MIG weld it? TIG it. Get a big Tungsten and make a couple passes without filler and the cleaning turned up high. Low amps ...

Re: Welding Contaminated Aluminum

I've never had the pleasure of welding on a casting but I've watched the boss do it more times than I can count. Almost all of them weld the same.....just like crap. Looks like you were running a little cold but that could just be the photo. I tried hot, cold, balance up ,down, frequency up and dow...

Welding Contaminated Aluminum

I finished up welding an aluminum housing for a 2" water pump today. The casting was full of electrolysis as well as somebody in the past had tried to glue it together possibly with JB weld type stuff. I scraped the crap off, bead blasted it, brushed it, heated it up with a map torch and brushe...

Re: Cool Stuff You Gotta Have

A buddy of mine collects stuff like that. He has an old grinder and a blower for a forge that were originally designed to hook to an overhead flat belt pulley. He collects hit and miss engines, old air compressors, has an old water punp that moves liquid on the up and down strokes, etc.... He's bee...

Cool Stuff You Gotta Have

I'm a hopeless collector of STUFF. I like STUFF that not many others have. Stuff like my 1950 Mall 2 man chainsaw. It is cool but looks dangerous. I like all my friends too much to actually get it running and play with it. One of my other treasures is my 1935 Yates American grinding wheel. I figured...

Re: miller econotig

I had one for quite a while. It's a nice welder within it's limits. It was near new condition when I sold it a few weeks ago. FWIW, I sold it to a retiring refinery welder that did TIG/stick for a living. He wanted it for his home shop and figured it would do everything he would need it to. I sold i...

Re: Fabtech

I float in and out of a few forums, mainly Cobra and Fe Ford forums. One thing I hate is the one or 2 righteous SOB's that know it all and continually have to try to prove it.
Besides that,,, being a newcomer here, I didn't realize that the posts were that old.

Jackson Nex Gen

This seems like a good a place as any so what is your favorite lid and why? I have a buddy who owns a welding supply and made me a 'deal' on a Nex Gen a few years ago. I love it but I'm always looking for the better mouse trap.

Re: Lincoln Square Wave 200 tig welder review

I've been using mine for a couple of weeks. I've used every function throughout all settings. It seems to be a nice solid welding machine. My only complaints are that the arc stinger lead separated from the electrode holder and you have to completely disassemble the holder to replace the cable. Ther...

Re: How do you guys bevel pipe?

Not for spec but I have always butt together for best fit, tack them together and groove out both pieces at once with grinder then weld. Never had an issue. I did thousands of feet of 12" pipe for pilings that way. We made 40' out of shorter random lengths from 10-20 footers. Never had one fail.

I think it was a little bit of everything. It has been getting away for a while now. I started noticing problems last year so figured it was wire and swapped it out. It got a bit better and so compensated with setting to get it "good enough" . My welding is truly what you call down and dir...

OK,,,,, I got a new whip/stinger/gun setup. I got a new regulator. I know that swapping out a bunch of new parts all at once doesn't diagnose the problem but I'm tired of f'ing with it. I need to get some stuff hot glued together.

Re: WTF?? Dirty Mig

Pull the whip out of the machine and check the condition of the O-rings. I'm guessing one or both have deteriorated over time and have either shrunk or split, limiting gas coverage and admitting air. Barring this, check the length of the whip for cuts or other damage that may cost you coverage at t...

Sounds like you are troubleshooting as I would, eliminate the obvious one at a time. If that doesn't cure it I would start looking at the "hidden" areas.... First make sure wire drive system is working as it should, no slipping, sticking etc. Next I would make sure your constant voltage w...
