Usually when the draw rate is going to be a problem, switching over to propane or Natural gas is the answer...unless you have a very small tank it's not normally a concern
When you work on farm equipment, a standard tool is a GIANT rosebud. They draw a LOT of acetylene!
I have a big tank and I sometimes wish it was bigger!
Yea the big rosebuds can draw a lot, no doubt there! When you get real big propane is the way to go, More btu's, and the tips seem to not overheat as easily, at least In my experience
biggest setup I've used was 2-3" in diameter (it was quite a while ago now, I can't remember exactly) and we needed a liquid oxygen tank to feed it, propane of course, it was to straighten a "mag beam" that had been dropped as a result of a crane cable snapping...it looked like 40ft of spaghetti ...2 of us + consultant and 18 hours later it was straight (the two of us heated and the consultant directed)
Same place we had to bevel 3" plate with a radio graph, because of the bevel it was something like 8" or 10" of thickness, only tip we could find to do it was propane, and again a liquid oxygen tank
I got nuthin after that story of yours! You win!
Where did you exchange @6.5 Fan ?I get to drive to town today and exchange my mig tank for a new one. Welding feet on a new wind break yesterday, hmm run out just as things get tacked in place. I bought my tank several years ago, Air Liquide will only sell the smallest tank but i don't weld enough anymore to justify paying a yearly lease and have large tank.
Huh, I've had my KMS C25 and argon tanks refilled/exchanged at Barry Hamel in Saanichton and they didn't bat an eye.I moved from Victoria to North Cowichan (near Duncan) about a year and a half ago. The tank I got at KMS just ran out, and rather than go all the way to KMS in Victoria to refill, I looked for a gas supplier here. Found one, sorta, Praxair/Linde:
Me: Do you refill privately owned tanks?
Him: Sure do.
Me: Great- I've got a 110CU 75/25 Argon/Co2, what will it cost?
Him: Can't do that - That's a "Lease Size" - only allowed to fill small tanks. You got it from KMS and the only people that will fill it are KMS. But they don't tell you that when you buy the tank. I've had lots of people return their tanks to KMS when they find this out.
Me: ??!!!!
Anybody know about this? Have a different story? Can shed light? I originally expected to have to drive my gas burning truck rather than my nearly-free-to-run electric car to Victoria anyway, but the "nobody else can/will fill it" is a bit of a disappointing surprise.
Just read backwards to post #69.
In my case Saanichton is a few K further, so no advantage to me unless they have much better gas or much better prices. . But it's interesting to hear that this is apparently a just choice by the particular supplier.Huh, I've had my KMS C25 and argon tanks refilled/exchanged at Barry Hamel in Saanichton and they didn't bat an eye.
Would be a shorter trip taking the Mill Bay Ferry.In my case Saanichton is a few K further, so no advantage to me unless they have much better gas or much better prices. . But it's interesting to hear that this is apparently a just choice by the particular supplier.
True enough, but I accumulate reasons to go to Victoria before making the trip, most of them would be closer to KMS since I rarely have any reason to go up the peninsula, the ferry is not free, and with the ferry I am less flexible about the timing. Plus, on that particular ferry you can't even use a BC ferries card!Would be a shorter trip taking the Mill Bay Ferry.
If you transport them upright then people know what you're haulingNot like I don't go to Victoria regularly anyway, but I do like to minimize use of the aging truck, and I do think transporting pressurized cylinders upright is "Good Idea".
