You know Jeff, that would echo through the halls so bad at my school they'd hear it in the office on the other side of the school. My brother had a pop tart and they used a propane torch to warm it because they didn't have access to a toaster. And then another guy took a pop tart and put it on the strip heater we use for bending plastic.
My dad used to take plastic water bottles at his old work place and tape the hell out of top of it and attached it to a massive air compressor. Let the valve go and made a blast like a bomb going off. Boss runs out-couldn't figure it out everyday for like a year.
A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none.

Must bot have been the same teacher like we have here.

Oxy/hydrogen gas welding is used to torch weld aluminum by some that make motorcycle tanks and other parts.
It is said that it makes a nice clean weld.
Well that answers That Thank you all I was just hoping to use a gas that I all ready have and pay lease on the tank. I use the tri-gas when I mig stainless I have it set up on my Millermatic 200 that is set up to run Stainless only. I priced out a new Lincoln
PRECISION TIG 275 today. Well lets just say I will be waiting a while for that added machine ($4800). I need to get a larger Lathe first. I did order a Larger tig torch today though. An 17 air cooled, When I got my Squarewave 175 it had an LA-9 torch on it with a 125 amp rating so that was limiting me some as well Plus burning the crud out of my fingers when I would push it.
I think for now I am gonna do the heavier steel and stainless with my XMT 304. I will invest in a pedal and just lift start it. Oh boy something new to teach myself. lol

We used ziplock bags.
I have more questions than answers

...nah I got booted out of woodshop a few times too.

Oxy/Acetylene can be fun lol We Started with plastic oil cans quart then gallon then 2.5 gal then a 5 gallon pail and a 30 gallon drum. After we set off the 55 gallon drum we decided we had better quit before some one got hurt. It removed all the grass in a 20 foot circle and took several minutes for the lid to come back to the earth. Oh please don't anyone try that.

Reminds of the first time we lit off Tannerite on the farm. We decide that shooting it wasn't worth it, so we took a bottle rocket and a shop rag and lit of 2 lbs 25 ft away from us. We surrounded it with unopened, empty diet cola cans. We haven't found it yet, but we are sure that somewhere in the back of the shop is an aluminum can that is shredded. Also scared the hell out of my grandfather-the house shook like a bomb went off. I guess the lesson is follow the insturctions and you won't learn and have no fun, but you may live little longer.

The LEL (Lower explosive limit) for hydrogen is 4% in atmosphere (20.9%oxygen at sea level). 5% in argon is a non-issue, as it's dispersal around the puddle much further dilutes it. It's not uncommon to have a slight "flare" around the cup when using up to 5% hydrogen, as it will still burn off once it meets oxygen while hot, but this is not a hazard. It's not unlike your butane lighter diffusing from pure butane to a mix that will burn in air a noticeable distance from the nozzle it comes from, and you're already looking at an arc of significantly high temperature.

What good story does not include beer.

Ironically there looking at bringing back propane as a refrigerant in cooling systems. And most of the new blends use butane as a stabilizing agent to make it less explosive but slightly more flammable.
I have more questions than answers

The world is taking an interesting turn when putting explosive gasses in a system that compresses.
Might work okay and be better than destroying the oxone layer but still, you would think we could make some new refrigerant that was just plain perfect, but no.

Ammonia is a perfectly good refrigerant. I have a few ammonia-cycle refrigerators that can keep my food frozen with barely more heat than a Bic Lighter makes.Olivero wrote:The world is taking an interesting turn when putting explosive gasses in a system that compresses.

Toxic as hell, in a leak, but that' s a local issue. No ozone issues, so the global warming folk should stay quiet.
Saw an awesome design that used solar power to drive an ammonia cycle, and barrels of brine to serve as a thermal storage mass to keep it cold when it's dark out. One was sized as air conditioning for a small space, the other as a freezer for long term cold storage. Expensive build, though.

Put a flint lighter in a milk bottle and fill said bottle up with oxy/lpg or acet mix. put lid back on and the throw said bottle in the direction of the Jokee. The force of the bottle hitting the ground causes the flint lighter to spark. Note do not do this anywhere other than private property, as it will most likely get you fired, expelled and possibly blacklisted.
