Anybody tried one.
I’m in need but don’t know if I’d ever use it again???
Don’t like to buy Ont time use tools.
Any idea of quality?
I’ve read good and bad just wanting real world information.

NOT the HF unit, but body guy's used one for 3+ decades.he uses 1000s of the studs  every year. Bought in NC..I call it the porcupine machine..another Canadian invention.
Really a simple device not much to go wrong. Bit of a 'learning curve' but it's the PROPER tool for doing quality tin work !
3 studs removed the dent in ,my #1, D1-14 gas tank 15 years ago.....

I have to ask (I’ve been wondering about this) what safety precautions you took to use this on a gas tank? I can see this being used for this purpose.

if we ever had to weld on a tank at work, shop rule was empty, blown dry and then dry ice chunks to force fumes out and leave CO2. If you can’t do that, I’d drain, flush, and fill with water JMHO

gas tank welding - empty , rinse , run exhaust from car into tank until to hot to touch , let cool and weld or solder .

Got a 96yr old uncle that has been welding gas tanks like that with an ox/acetalyne torch for 70+ years.

I have welded on small gas tanks and never a problem. But one mistake is all you may get.

Forty years ago, I saw the after math of a mistake. In a tractor junkyard. A 55 gal barrel strapped to water wagon. The barrel was the bigger gas tank for a pump to spray water on construction sites. The consensus was the strap was being cut with a torch. This was a yard that had done very little scrapping, and I know the water wagon had been there years. And a part of town any gas would of been taken very soon. So it was empty, but the old time gas was different than todays. But those fumes went boom big time. The man doing the cutting never made another mistake.

I have wondered is using the exhaust from modern clean burning cars still a good way to remove the oxygen from the tank?????

what comes out of the exhaust pipe is CO  ... neither will burn.. The goal is to PUSH all the gas fumes out and leave a blanket of no oxygen... You can also use Nitrogen or CO2..

I wouldn’t be buying this for gas tanks but to use on my truck project. Helps to think about future uses when buying a tool that won’t get used often.
