Looking for a plasma cutter
 
Hello,
I'm looking for a reliable plasma cutter to do a few repairs. Nothing to expensive. Does anyone have any suggestions?

Ayuh,.... Those words bolded rule out you gettin' a plasma cutter,....

The chinese stuff is Cheaper, but reliability is questionable,....

Buyin' a unit from Miller or Lincoln, Ain't cheap, but Are reliable,...

You are on EARTH---if that puts you near Illinois PM me--a welder /neighbor is retiring and selling off his equipment---

Even used---professional grade welding rigs are $$$$$$$

If you just needed to cut a few things for repairs could you possibly use carbon arc instead? As mentioned by the other posters any plasma cutter that's worth buying is going to be quite expensive, even if you can find a used one.

Carbon arc? That takes some air and some current.

To the OP, you need to define what your budget really is in hard dollars. You're not going to get a good answer here, this isn't really a welding site. I suggest

They have everybody from novice welders to fully ASME cert'ed duplex pipe welders 18" x 3" wall.

I need a plasma cutter that will cut through 2 inches thick! If I go through a company like miller or Lincoln, I will pay way more than I can afford. I decided to go with an import machine called the LONGEVITY 100amp plasma cutter. Has anyone ever used a LONGEVITY plasma cutter? This will be a very powerful plasma cutter capable of cutting through 2 inch thick steel! most people would not need to use something this powerful. they also carry smaller more portable plasma cutters that will run on 110v or 220. This plasma cutter is going to be a 3 phase plasma cutter that I will use to cut through 2 inch thick beams!

I placed my order yesterday and am very excited to get the machine but would like to have some feed back and experiences shared since I have a 30 day satisfaction guarantee. Thanks.

Workingman, I have a feeling you're going to get a lesson on longevity of an offshore plasma cutter :whistling2:

The stuff that Harbor Freight sells, is the same that you see at Home Depot, Lowe's, Wal-mart, etc. Chicago Tools may be colored different, but all the same.

If this is only going to be a few jobs a year. You may be better in finding a local metal shop with one. A decent Plasma cutter would need 240vAC service. The bad side is that unless you have used one before. You can hurt yourself really bad. We are talking Third Degree burns.

And how much it costs for the gas. I just wonder if their current service is able to handle the load. Plus 2" steel stock is not light to begin with.

The OP is going to need at least a chain hoist, depending on the size of the stock.

Ayuh,.... What Gas,..??

He said he's got 3 phase power,.....

Plasma Cutters use an inert Gas during the cutting process.

Nope,.... Plasma cutters use compressed air,....

A simple hook-up to an air compressor,....

2" thick plate is huge. It is really unusual for it to be cut in anything but a professional setting, and unusual for pro's to use any machine other than one of the biggies ( Victor Technologies, Red, Blue, Yellow and Hypertherm)

Good luck

Every one that I have seen. Uses Inert gas, not Compressed air.

I worked in heavy steel fabrication for 20 years. Some processes like gouging special stainless steel pipe will use inert gas to increase the heat and minimize the amount of carburized material. But 99.9% of plasma cutting is with compressed air. Could you be mistaking air filters and desiccants for something else? Could you be viewing machines in a particular industry? Could you be mistaking a MIG or TIG machine for a plasma cutter? Or could you be wrong?
