I'm attracted to the Meco Midget for welding (smaller is better for the art I do), but it doesn't cut. I haven't seen a way to have two torches simultaneously hooked up to one set of bottles, or some sort of quick-change device. In either case, being able to use a very small torch for welding and quickly being able to switch to a Smith Aw1a for cutting would be nice.Are either of those options available? I'm new to this, btw.
Reply:Have you done a search for quick-change connections? I'd swear there was a recent thread about just that subject and one connector discussed was the Western Brand; maybe look for that word. I see no reason why quick change connections would not work well, and yes, they are sold specially for use with welding gases. Just remember that the regulators need to be readjusted every time the torch is changed, unless you use injector types and the settings just happen to be close enough for both.

Reply:I'll put this out their, how about building yourself a manifold, I think some of us have seen how the schools have a number of tanks hooked up to a manifold system and then the reverse for the work stations with their own regulators. But don't recall how the flow was regulated off the tanks so flow could be stopped in an emergency.
Reply:how hard is it to unscrew the hoses from one torch and screw them onto the other torch?
Reply:I use quick connects on everything at one job, and at the other job screw the hoses on.Advantages to QC's: easy to change torches; helps keep crud out of the torch and lines (with a little care); less wear; protects the seats on the torch fitting and the line end;Disadvantages: add length to the torch body; can be released accidentally in use (hang up on the collar and they come free, usually without dropping off.. "where'd the flame go?!?"); the male part (on the torch) can get banged up when not connected (need to have a few spares around)Advantages to screwing the hoses on directly: no extra weight; less flow restriction; no mechanism to get dirty/broken in a hard environmentDisadvantages: have to be real careful to keep line ends clean; need to clean and inspect seats to prevent leaks; threads and seats eventually wear out or strip, even with a lot of care;With the QC connectors, in the worst case, they can be removed and the hose connected directly. Strip the fitting, you are out of luck.The smallest torches at the shop with QC's have a short pigtail installed (maybe 3 feet long... made up from a damaged hose set by installing new ends) between the torch and the QC end. This avoids the extra length and weight being right on the torch. Still need to be careful not to snag the female QC and disconnect accidentally.

Reply:Originally Posted by denrepFor your application I think that connectors at the torch will make it feel awkward and less nimble. You could run separate hoses with quick connects at the regulator.But "Y" not this?Attachment 51001
Reply:Or maybe the quick-connectors would be easier, like denrep said. The awkward-issue with the quick-connectors: On the Koike page, it looks like there are Regulator-To-Hose Connectors, so there wouldn't be any extra weight on the torch; you'd just need two sets of hoses. Also, they have Hose-To-Hose Connectors, so you wouldn't have to unscrew the hoses to refill gas.
Reply:You could use tees at the cylinders, and run two sets of regulators. No need to disconnect torches or hoses, torches can be at different locations, and no need to change settings.Tees are listed here, scroll to view:http://www.westernenterprises.com/en.../PDFS/wi28.pdf
Reply:How about two three way valves, total cost would be about $50.00 |
