Re: Exair cabinet cooler

I strongly recommend that you take the plasma out of the cabinet. In free air you will not reach duty cycle cutting 3/16". Perhaps on 1/2" on a day that is 104 F or higher you could as the arc voltage is much higher (amps x volts = watts.....more wattage output = higher heat developed). Hy...

Re: HD Plasma help

Downdraft is best for cut edge smoothness and quality however it either requires a large filtration unit or a blower that simply blows the dust (and your shop heat) outside. Water tables are very effective without requiring a blower / filter, and keep your heat inside, however to use Hypertherm's Tr...

Re: Finecut Woes

The plasma cutter itself does not need a ground rod, however the computer and the machine electronics may. The idea of an earth ground is to route stray electrical energy (aka: noise, RF, EMI, etc.) back to a good earth ground instead of having it inductively or capacitively couple with wires and ca...

Re: CNC Plasma cutting eye protection

This is from a Hypertherm operators manual. Plasma cutters range in power level from 10 amps to 1000 amps, just like with welding, more amps equals a more intense arc. Different shading for comfort and safety is recommended based on the power level of your system. In many air plasma cases a shade 5 ...

Re: Cutting 1/16' SS 304

You will get less dross with air on all materials, but slightly less oxidation with nitrogen. For best cuts on thin stainless you need a high definition plasma, a laser or a waterjet, unfortunately. The best cuts are done following book specs with the Finecut consumables. The issue is that many low ...

Re: Finecut Woes

You do not mention the thickness of the material, however with your symptoms (not cutting through all the way on the whole sign) I am going to guess you are cutting 14, 12 or 10 gauge steel. Slowing the cut speed is the first instinct that everyone has with this issue, however it is not the fix, and...

Re: 45xp or 65 xp

Both systems use the same torch and consumable designs, so cut quality (at 45 amps or below) is identical. The 65 will pierce and cut 5/8" all day long in a mechanized application and will edge start and cut 1-1/4" by hand. The 65 can operate on any input line voltage between 200 volts and...
