Re: Torch not firing

Sounds like an electrical noise issue. If you jumper the start signal (input CPC port on pins 3 and 4) with the torch within striking distance of the plate...the torch should fire and pierce through the plate. If it works this way.....but not when interfaced to your control then electrical noise may...

Re: 1/8" aluminum diamond plate

If you have a fast reacting torch height control (it will rise over every bump) then the best cut quality is at book specs for the nominal thickness. If the height control is delayed, slow or sluggish, then cutting with the bumps down is the next best thing. Jim Colt Hypertherm

Re: 1.25" carbon with Powermax 85

The Powermax85 is rated to pierce through 3/4". With an edge start it can do an excellent job through 1.5" steel. Nothing difficult about the specifications, simply go to the operators manual, go to the 85 amp cut chart and follow the cut specs exactly as stated. cut height, cut speed, arc...

Re: Those of you who regularly cut 1/2 and thicker stuff...Q.

The 45 amp pierces great on my machine. Here are my suggestions: -Lower the water to an inch or so below the plate......water in contact with the plate affects piercing. -Increase lead in length or location so the slag pile will not collide with torch at end of cut. -If you can't make a longer lead ...

Re: going to upgrade from a 600 to a 85, have questions

The Duramax spring electrodes outlast the earlier Powermax600 by a lot. Compared to the Powermax45, the Duramax electrodes show better life, often about a 50% increase. Jim Colt Hypertherm Does the electrode on the XP45 outlast the 45 by that amount as well Jim? I'm still pondering whether to swap.

Re: going to upgrade from a 600 to a 85, have questions

25' torch and 50' torches function the same, cut the same, use the same consumables. The Power supply recognizes the torch length and adjusts cut air pressure automatically to compensate for different lead length and pressure drop. The consumables used in the newer Hypertherm systems on the Duramax ...

Re: O-Ring Issue???

Part of the torch body cooling in Hypertherm air plasma torches is a bleed of air around the top of the retaining cap. It is normal.

Re: Powermax30XP wiring interface for CNC

As a Hypertherm associate of 39 plus years (and I like my job!) I cannot recommend any modifications to the wiring in our units. I would recommend that for CNC use you limit the maximum cutting thickness to about 3/16" (4.5 mm)....this will increase the duty cycle and will allow for good consum...

Re: Hypertherm 65 3/8 plate

Dross is caused by: -Cutting too slow -Cutting with torch too high. -Allowing the metal to get too hot. 1. Experiment first with speed.....do test cuts with incremental increases in speed. 45 inches per minute using 65 amps is the minimum dross free speed....so that is why the spec is in the manual,...

A picture of the torch would help. Early Snap-on plasma's used an old Hypertherm torch design, if I saw it I would recognize it.
