I have a miller spectrum 375. and I have only had to change tips once in 4 years. I cut up may 55 in my pix with the machine. Very nice cuts with little to no warping, although they can be sharp and cut like a razor after.LOL It will do everthing I will ever need to do as far as plasmas go. I am very happy with it. (desclaimer:I AM NOT afillated with miller in any way shape or form).

I think I couldnt go back to a torch set up, Tim

here is a pic of the edge of a 3/8" bracket we cut. It has only had a quick pass on a wire wheel.

I have an old thermal dynamics and it design for 1/4 in and ways in at about 125 or more lbs. but works great and have cut easily 1/6 diamond plate steel sure was sweat when it cam time to cut long way some thick corrugated sheet metal for a shed. the PARTS WERE VERY REASONABLE TO BUY. that is a crucial issue.

Gents,

I am also in the process of looking for a plasma cutter. I am looking at this one http://cgi.ebay.com/ws/eBayISAPI.dll...K%3AMEWAX%3AIT and wanted to know your thoughts on Hobart products. The reviews I have found have been positive.

Also, I know you can you use shop air (compressed air from a compressor) to cut with but after reading the attached article http://www.thefabricator.com/PlasmaC...le.cfm?ID=2135 I was wondering if the steel that I get from a local steel supply house is carbon steel or some other steel (I know very little about the different types of steel) and does using shop air with any type of steel make any later weld not as strong? Is it better to use oxygen instead of shop air?

Any feedback you guys can give me on the Hobart 400 and whether or not shop air weakens welds after you have cut an edge on shop air would be greatly appreciated.

Thanks in advance.

Brent

Never heard of a plasma cutter that uses O2. You would have to have tanks the size of railroad cars. My Lincoln Procut 55 uses air at the rate of 12 cfm at 60 psi.
As to your other question. The change in metalurgy while cutting with air/plasma is so minute it is not even in the equation. However, using shop air in your mig is not recommended. It will cause degredation of the welds.

LOL, That's not the half of it! I saw this done once when some guys played a joke on a new employee who started telling everyone what they were doing wrong on his first day on the job. "Degraddation" of the weld? You betcha!

I have a TD Cutmaster 51 that I bought from an Ebay store and saved well over 200 bucks vs buying it local. I'm happy with it and after several years, it's working very well and consumables are lasting. And first day on the job...I usually kept my shut for a long time until I found out what kind of a group I hired into lol
