I finally got to try out the new plasma cutter today. I tried it with an adapter on 110v but it just popped the breaker. I had to do some wiring to get 220v in the garage and now it works!
At first I tried it at 30A cutting current but it wouldn't go all the way through so I kicked it up to 50A and WOW! It cuts through 3/4 inch steel bar like a hot knife through butter.
Wow..
And probably a lot quieter than my cutoff wheel.
Make sure you have a fire extinguisher handy.
Do you have a loaded stream extinguisher?
I carry one with me when when I do plumbing after I was repairing a shower valve and the fiberglass enclosure started smouldering, had to go down to my truck and get my extinguisher and walk calmly past the tenants watching TV downstairs

They never knew...
I have a dry-chem Kidde in the garage. I've had to use one a couple of times. Once on somebody's car on the freeway and another on a propane lantern that was cross-threaded by somebody else. After a couple of my mishaps as a kid I'm almost paranoid about fire.
Can you give me a call about your springs? 620-210-1160.
Just a thought on various types of fire extinguishers for protection from fires from sweating pipes or any other use of cutting devices near ordinary combustibles such as wood. I strongly suggest a garden hose with a nozzle for the simple reason that none of those extinguishers remove any heat. They primarily remove the oxygen component of the fire tetrahedron: heat, oxygen, fuel and an uninterrupted chemical chain reaction of the 3. Some extinguishers such, as halon, interrupt this reaction. This is also how we put out gasoline fires, by literally removing the flame from the fuel, interrupting the chain reaction. (of course, we use foam and water)I personally went on several large fires that were caused by sweating pipes and at most of them, there were 3 or 4 spent extinguishers found amid the charred remains of the building. One was a fire on the 10th floor of a high rise building and it wasn't sweating pipes, it was refinishing wood with a flammable varnish. The workers were trying to escape, but were trapped in the garage by fire hoses.
The point is that a garden hose, or even a pump sprayer full of water is a thousand times better than any dry chem fire extinguisher. Carry on...Mark Edit: Of course they make pressurized water extinguishers also...

You're right about that. Actually water removes both the heat and the steam displaces the oxygen. Water isn't good on electrical fires though. When I was working at Boeing when we had to machine magnesium we were trained to put a special powder on magnesium fires because putting water on it would create explosive hydrogen gas. I don't remember what that powder is though.

Yes you are right, but it actually doesn't produce hydrogen, it is an oxidizing agent that releases its own oxygen and most of us know what adding oxygen to fire does. Magnesium and other metals release hydrogen when exposed to acids and we all know that lead/acid batteries also release it. One of my first really big haz mat fires was a large hydrogen tank being filled by a large hydrogen tanker on fire. It was in a residential neighborhood. Hydrogen burns invisibly, but we could see flame while paint and other things burned off, but when that was all gone, we could just hear it. It burned all day with unmanned ladder pipes and deck monitors and we pumped millions of gallons of water. It was really spooky when the fire engines started running out of fuel and the water streams started dying. They asked for a volunteer to go in and fuel the trucks and about 20 of us did, but they picked an old timer. When it was over, after flying in a tanker expert from CA and him turning the right valve to shut off the flow, there was 3 feet of water in a flat area with no where to go. Kind of an anticlimactic ending. The experts estimated a half mile wide fire ball if it had exploded and we were about a quarter mile away ...Mark edit: I actually found an article about it:
Gotta' apologize Edwin, magnisium does not release oxygen, but from the water it actually takes the oxygen and leaves....you got it, hydrogen gas from the water. I used to teach this stuff, but that was a lot of brain cells ago...

Perhaps I should have stated it more plainly. Yes, the reaction liberates the hydrogen gas from the water. Magnesium is an element while water is a compound.

That is why I questioned if he had a loaded stream, just pressurized water,
I acquired a few of them when we upgraded a high rise building,
I got about 20) 2 1/2 gallon loaded stream extinguishers, 20 pin racks and a lot of new hoses, also Fire Annunciator panels with strobe lights.
Back in the year 2000 I bought a nice Gorman Rupp 5hp high pressure fire pump for home use and 200 feet of 1 1/2 hose and an assorted nozzles,
I have 28,000 gallons of water in my back yard if I ever needed to use it.
I still want to find a used Hale 2 man fire pump for a good price.
Although where we live, the response time for the fire department/ paramedics is less than 3 minutes.
I still like to have my own system.
Especially at Christmas time I have 3 loaded stream (pressurized water extinguishers) in the house because of the tree.
You just got to love Class-D fires, magnesium, titanium, my brother in law machines those metals at his machine shop.
On the extinguisher I use when I do any soldering I installed a fog nozzle, In addition to using nomex blankets I like to soak down the surrounding area where I am going to work.
When I am finished with any soldering job, you will never see burned/ charred surroundings like from other smell bad plumbers.
Edwin, I will bring you a 2 1/2 gallon loaded stream extinguisher when I bring you the springs, they are fun to take in your truck and spray people in the crosswalk.
Mark,
Have you ever used animal protein foam or got any on you?
The messy nasty stuff, the kind made out of animal blood?
Wow..
And probably a lot quieter than my cutoff wheel.

Maybe you guys should buy this stuff if you're worried about starting fires ?

Jim
We still had the protein foam at the airport when I first started, nasty stuff. We went to AFFF (aqueous film forming foam) until they came out with alcohol in gasoline, which broke down the foam. We then went to alcohol foam, which we now have plumbed into the system of every pumper. It is used on every fire because it limits water damage. You should come to our bi-annual city auctions, they sometimes sell pumpers that are pretty cheap. I saw a fully equipped ALF 100' ladder truck sell for 5k. Would have been a cool toy and great for trimming tall trees. We also sold 3 pumpers to Nogales Mx. for 1 dollar each, maybe you could catch a deal like that. ...Mark

Fun stuffWhen I got mine the rubber bushing was mostly gone. after I got it cleaned up I went to the hardware store and found an All thread connector that fit and a bolt that fit that. I drilled a couple holes in the bottom of the stick about 1 1/4 from the bottom to plug weld to the connector and also welded around the bottom. the bolt just welded the stub.
Have heard a clunk on shut down lately so just ordered two motor mounts and getrag transmission mounts from Rock Auto. $28 shipped isn't bad in my book.
Imagine the stock mounts are totally thrashed by now.
