Power Plasma 60 Review

[Mr. Welder]

Good Grief, Charlie Brown, I could cut better with a torch. You need more air pressure to get a clean cut. My plasma requires 90 psi. Don't angle your torch head so much. That actually makes the metal you are cutting thicker (angled cut versus straight cut). Like anything else, PRACTICE and do what works for you. Good luck. Jim

Don't use 90 psi...Not on our cutters. It isn't needed.

75 PSI max is the highest I have used on the PowerPlasma 70 and that was around 1.25" steel plate. I was playing around and have no real reason to cut that thick or it be a clean cut.

Looks like you had the torch at an angle, left or right of the cut and not enough air pressure. You can see it was a good vertical cut, but the torch looked like it was leaning and low on air pressure. So basically you cut 1.5" with low pressure.

Long as nothing caught on fire, no burns on you, mission on 1.25" was accomplished with a little work...

Can I cut steel using air instead of argon with a Power TIG unit with the appropriate torch? How does the Plasma Cutter differ from the Power TIG unit??

John,

Plasma cutting was invented as an off shoot of trying to create a plasma welding system using a techinque similar to TIG.

But no, its not a good idea to even try. The amperage and voltage issues are make it not possible. The multi-process units we have actually have two separate boards in them to accomplish this. The Plasma has around 200 OCV's. The Tig has around 90. Tig has 200+ amps and the plasma has around 50-100. The circuitry is much different, including the way the pilot arc works.
In short, please don't experiment with this idea.
