Re: Not cutting through once cut is started- Powermax 125

So, to rephrase my question about the cutting specs: What amperage and consumable set are you using on each thickness? Can you show a close up picture of the nozzle and shield, so I can see the nozzle bore? Lower amperage and consumables will provide better cut quality on thinner materials. Varying ...

Re: MINIMUM AMP SETTING ON POWERMAX 45

The cut charts listed in the Hypertherm operators manual are developed by cutting a lot of materials and thicknesses. The goal of these specifications is to provide good, repeatable cut quality in terms of edge angularity and minimal bottom dross. With any plasma system you could cut 16 gauge steel ...

Re: Any idea why I am getting angled cuts?

There are two basic types of cut edge angularity with Plasma cutting that tell a story: 1. Relatively similar angularity on all four sides of a rectangle. This means that the torch and consumables are likely in good shape. You can minimize the angularity by adjusting your height control lower, howev...

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...

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 ...

Assuming that you are 100% sure the torch is at .08" (at the arc voltage you set), then I would next check the following: - Be sure your air pressure is set in auto mode. - Install a pressure gauge hardplumbed on the rear panel air inlet on your Powermax. - Monitor this gauge when air is flowin...

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 ...

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.
