Re: parts look better with a drag tip than with a shielded tip on plasma cam

The best cut quality with the Powermax85 on a Plasmacam that has advanced height control and ohmic contact: - You need to use the mechanized consumables as listed in the many pages of mechanized cut charts in your Powermax operators manual. I strongly suggest the Finecut consumables (using the 948 s...

Re: PlasmaCam RENEGES on eBay Sales

Plasmacam does do a great packaging job. I bought a 50" pan brake from Grizzly about 6 months ago......weighed 1200 lbs. Very poor packaging and a lot of cosmetic damage (I made Grizzly take care of it...not the trucking company). Jim

Re: PlasmaCam RENEGES on eBay Sales

The shipping sounds right for the size and weight as well as travel from Colorado to Kentucky. And the shipping cost is set by the trucking Co, not the plasma cnc machine builder.....FYI!

I shipped a 700 lb machine to Utah 2 years ago from NH, it cost over $1200. Jim Colt Hypertherm

Re: Powermax 1000 howl when air flowing

The inlet pressure is critical, I always suggest installing a pressure gauge hard plumbed on the Powermax inlet fitting. It must be over 90 and under 120 psi when air is flowing through the torch. There is always a pressure drop between the gauge back near your compressor and the plasma (natural res...

Re: Changes in mild steel hardness after cutting

Does the edge harden regardless of whether the plasma has a water table or a downdraft setup? I would guess the water has a quenching effect. What about 1045 and similar? Does the edge harden even deeper, considering those steels can be through hardened due to higher carbon content, whereas mild st...

Max pierce capacity of 3/4" for the Powermax85 is the issue. If you pierce 1" you will damage the nozzle and shield very quickly. So either predrill holes or arrange your cut nest so the next cut starts on the edge kerf of a part already cut. Long cuts on a hot day could easily get you pas...

Re: Belt reduction suggestions

Properly sized servos most often need about a 10:1 reduction (there are other factors that would change this, but most cnc tables are in this range) and servos, again properly sized for the mass....typically are 3 or 3.5:1 ratio. This allows you to take the most advantage of the speed torque curve o...

When cutting steel with an air plasma, assuming you are operating at the optimum (not fastest) recommended cut speed, at the recommended physical cut height (always adjust recommended voltage so the physical cut height is correct) expect that the plasma arc will have a slight tailback, meaning the a...
