i did tig welding stick welding and oxy-acetylene welding in highschool, one thing i remember distinctly was that with oxy-acet and stick welding they were very firm in saying they didn't want us to ever weld a closed container. not sure if this was because of explosive dangers or what just remembe...

Yeah this is what I'm thinking. I was just wondering if there was some way to get around that.

I’m having a problem. I’ve been practicing my aluminum TIG welding by making cubes out of aluminum sheet For the second time now I can’t seem to be able to fill the very last spot. I mean the last spot that would seal the cube up. I keep getting black soot trying to fill the very last spot, like the...

I tried out my new aluminum carbide bit. Huge difference, just a light grinding of the top surface exposing fresh material. Much less crap in the puddle, still not perfect, but way way better.

a few tips for cleaning: get an aluminum-specific carbide burr. they have less flutes so you don't need to lube them to keep them from loading. also, get a new stainless wire brush, use it often. don't use any abrasive cutting/grinding wheels/discs unless you really, really have to and always file ...

CLEAN CLEAN CLEAN. What I had to do was wire brush make a cleaning pass with torch no filler to boil up crap and clean again. Finally added filler and ground the bead down and repeat till I get a clean base its a pain sometimes but it can be done. Yeah, it's bugging the hell out of me because I've ...

I’m having a devil of a time trying to TIG weld some cast aluminum. I’m a hobby welder, by no means a pro. Specifically what I’m trying to weld is a motorcycle swingarm. I bought a junk one so I could practice before I tried anything that counts. Exactly what is happening is the welds are very porou...

Tig welding.

Ok this is a bit of a newb question. When I weld 1/4" and up steel as it cools it sometimes cracks along the weld. What causes this and how can I prevent it? TIG welding if that makes a difference.
Thanks in advance.

I've bought a lot of Snap on tools over the years. The very best tools without question. However far too many times I've felt ripped off weeks after the purchase. I don't feel like that when I buy something from Sears or Northern tools. I don't go near the Snap on truck anymore for that reason.

Congratulations.

I took their one week TIG welding class. Good class, the instructors were great. You have access to virtually unlimited materials and supplies. I even got a small tour of the factory. I was blown away to find out they make everything in house. They actually make the mufflers on the engine driven wel...

Lincoln Electric has a school in Ohio. They have one week classes, I'm going in December.

I was assuming the classes there were good and it's great to hear my assumptions are correct. I'm looking forward to going to the TIG class in December.

well, it can be broken down into math. Depending on your flowrates, it can last anywhere from 4- 8 hours of straight arc on time. Say, 20cfh, and it will last for 4 solid hours of uninterrupted welding. Since the duty cycle of the welder wouldn't allow that anyway, it is kind of a useless figure. M...

I'm looking to replace my chop saw also, it's not my favorite machine. I been looking at the Milwaukee 14 in. Dry-Cut Machine 6190-20 http://www.milwaukeetool.com/ProductDetail.aspx?ProductId=6190-20&CategoryName=SC%3a+Chop+Saws But now I'm looking at this Northern Tool band saw. It's $200 . . ....

How long should an 80 CF tank of Argon last? I realize this is difficult to answer, but I need some kind of benchmark. How long a tank that size lasts for other poeple. I'm going through a tank about every 5 weeks. I only use my welder(Invertech 205) on the weekends. But those days it will get a lot...

Try some other places. I've experienced what you're talking about, but they aren't all like that.

I registered for the TIG class back in July, the earliest opening wasn't til December. The Motorsports classes were likewise.

I just purchased the Invertec 205 in July. I can't give you any comparisons I've never used the Dynasty, but I love the Invertec.

I'm curious to hear what it's like, I'm taking their TIG class in December.
