Been thinking about getting a plasma cutter. What are some general does, don't, old wives tales and what will they really do. Who makes adecent one? Looking to cut metal from roofing steel to 1/2", blast out stuck bolts etc. Plus not pay as much for oxy-acetylene gas every year.

I bought a Thermal Dynamic cutmaster 81 a month a go and I LOVE it. It will sever 1 1/4 and cut clean 1 in.It is a 220 volt 60 amp but it really cuts nice. and the best part was it was about 1850 on ebay.The consumables are reasonable and seem to last a long time as long as you don't forget to hook up the ground, not that I would know. I have done quite a bit of cutting 1/2 in and smaller and it works neat and fast. and some 1in small parts and it is so much faster and easier than a torch. I would reccomend that you get the largest one that you ever think you need as they are not that much more to buy bigger. One more thing. I used the gouging tip to blow out a bunch of weld that someone goobed up on a backblade that I bought and it really did the job fast. sure saves alot of grinding and time.

I just picked up a Thermal-arc 101 with the Machine 1 series torch. Thermal has did there homework with these new machines and the torch just flat blows the Hypertherm away.Hypertherm is getting real nervous about some of Thermals patents. It looks like the tables has turned around because everybody thinks ( cnc table makers)that you need a Hypertherm.In fact The guy that makes the table I am getting offered to sell me a 80 amp Hypertherm at cost.I Just got done telling him that I traded my 90 amp esab(awsome machine) 1500 for the Thermal 101.Thermal-dynamics actually makes cnc burn tables so when they say they won't cause problems with a cnc table they are not making it up.Yes I have access to a 100 amp Hypertherm and it does work good but they got some catching up in the torch area now. Just like it took Thermal a long time to catch Hypertherm.

Scott, What in the world are you basing your "blows 'em away" statements on? If you have some facts to back up that incredible statement then please share it with us. Otherwise, admit you are simply expressing a personal, gutt felt opinion.

I hope poor ole BuickandDeere won't take such unsubstantiated statements at face value.

Oh, BuickandDeere, do buy a name brand from a dealer you can trust!

Therminal Dynamics does make fine submarines:-)

I dish it out on occasion so I expect to take it on occasion as well. General Dynamics is the military division of General Motors. They are equipping the armed forces with Stryker (spelling?) armored troop vehicles that can't take a hit from a RPG. Factory is in London Ontario where they used to make off road equipment. Don't know if the rail locomotive production is still there or not? Sad to say every former Soviet and 3rd world country has RPG's laying around stacked like cordwood. Electric Boat Works and somebody else are the two US sub manufactures. Not much going on in that market since building the three Sea Wolves and refitting some Ohio class boomers into assault platforms for Navy Seals. If this Thermal who ever company really has took a step past everyone else they should worth a look.

Tom, If you see one of the torches in action you will get it.The arc stays very constricted along its total length.The Thermal also has a fold back curcuit to save your tips when cutting at hi amps if you hit your work piece(nice on a cnc table when using the exposed tip). You can also retro fit the one series torch to about any machine.The sure-loc tech in the torch does a great job of making the consumables last longer.

Tom it is not a gut feeling only what I have saw from using them.Hypertherm and all the cnc table makers seem to make way more claims that are not even true anymore.Let see like consumbles last way longer in a Hypertherm.

I still stick by blows them away.In fact my esab 1500 blow them all away in arc length on single phase power. If you need more details feel free to go demo them all. Like I have.

From what I know Hypertherm, Miller & Lincoln make good units. I've got a Hypertherm & it is fine. 40 to 45 amps to cut 1/2" & that'll run you about two grand$.

If you are thinking of getting one to save on your cost of gas consider plasma cutters use what they call "consumables". They call them consumables since they CONSUME all your savings, all your cash, all your money! Kind of kidding there, but consumables are expensive. I understand they represent a major profit center for the plasma cutting manufactuers. Check their cost first!
Plasma cutting is great, but it is NOT cheap!

You'll need a 40A machine to have any kind of cutting speed with 1/2" thk steel. I went into My local welding supply shop to buy a Miller which they sold but They recommended the Hypertherm, and they stocked ALL the consumable & wear parts for the Hypertherm so that's what I bought. They didn't stock many parts for the Miller.

I have a Miller 375 that I am really happy with. It cuts the ranges you mentioned, can operate on 115 or 230 volts. You are limited to how high current you can use on 115, but it is fine for smaller stuff. The other guy listed some great sites, the Hobart Welding Talk is especially good. The only thing I will change on my Miller is the ground clamp. It is nice and light, compact, all that, but I would like something more rugged. There are competitive models by other manufacturers, I have heard good reports on many of them.
