do any of you guys use a plasma cutter much ? I have a Simarc 520dp I CAN GET TIPS , 50 PACK FOR $30 and cuts 1/2 easily and I use it way more than cutting torch . I find a plasma cutter is a very handy tool to have a round for cutting all kinds of stuff , I don't here much about plasma cutters around here , and wonder if you guy think there much good for your kind of work, thanks John

I used to use one all the the time when we were doing retrofit mods at my last job. I preferred it to our cutting torch to

I recently got one for the shop a Hypertherm powermax30. their smallest. and it is invaluable as i work a lot with SS and Aluminum. Straight edge is a must for Aluminum, but i find it gets a lot of blowback regardless of pierce method. I recently got their Deluxe Circle guide kit. but as we are changing the power to my shop to 3-phase atm I have yet to use it. I have been trying to get a Plasma for years, but now that we do I can't see how we have gone without one for this long. In the future we are looking at getting a Plasma table for short run production jobs.

i had a small miller 110v plasma cutter. i believe it was the spectrum model. it was very handy for light material up to almost 1/8" then became obsolete when the consumable tips got too expensive if i could find them so now it's collecting dust on a shelf.

Cant you buy the Chinese ones off Ebay for it? I bought hundreds of electrodes and ceramic insulators for just $20-30 for my plasma cutter (not Miller)

that normally would be a good idea but working for a para-military organization with thousands of employees and a multi million dollar budget discourages me from reaching into my pocket for consumables.

I do a lot of plasma cutting, and even use it to wash stainless and aluminum welds. We have two Thermal Dynamic units at work. I don't recall the model, but they'll cut 1/2".

To make your consumables last as long as possible, put an oil seperater and dryer ahead of the plasma cutter. Dry, oil-free air is essential to making the tips and electrodes last.

I also have access to dry nitrogen at work, and this is a help on stainless and aluminum. It's bone-dry, oil free, and does not make excess oxides in the cut. Carbon steel cuts better with air, however, probably because of the presence of oxygen.

Two cents....

Thats good to know Otto, as we will be getting nitrogen for using our cutter for out of shop operations.

I have been running a smith torch for years and over the years I have learned to like both... I love plasma but have no money for one and only 120 v outlet and I work with 3/16" and 1/4" plate...I was working on a plan to build one but felt it was to much of a saftey risk and realize either i buy cheap model or save up for better one..

I have a cheap Chinese dual voltage plasma cutter. I use it a lot on plate/sheet, and when I just want to make quick rough cuts. I wish I was better with it, and could get more accurate/clean cuts, but for me it's more of a time saver to hack metal down to rough sizes.

I use a Miller 625 Spectrum X-treme all the time. I cut a lot of steel and aluminum with it since we don't have a shear in the shop. They say it will do 5/8" plate although I haven't tried yet.
