Re: 45xp voltage reading or torch compatibility

You can use either hand or machine torches that are made for the Powermax65, 85, 105 systems on any Powermax45 XP. As Tom said....the torch is not where the arc voltage is read....it comes from the power supply. Did you specifically ask the dealer to check the Powermax unit for arc voltage output? I...

Re: Tip Slag Finecut nozzles

Copper Plus are for 1/2" and thinner, any amperage. They work with Fine cut. If you cut thicker than 1/2" (thicker means the power supply produces a longer arc, higher load voltage) the electrode life starts to creep back to the same numbers as the standard electrode.....why pay more money...

Re: Nozzle Issue

Any discoloration on the end of the electrode and inside of the nozzle.....such as in the previous pictures is fairly normal. It is where the pilot arc starts at the beginning of each cut cycle. The discoloration could be from dirt / grease (from your fingers) when installing the consumables, small ...

Re: End of Cut - Compressed Air Off Delay

The air flow after the cut is called "Post Flow", and is absolutely necessary for consumable parts life. The end of the electrode inside a plasma torch reaches 3100 degrees F while cutting, the post flow cools this between cut cycles. If you could reduce the post flow...you could save air,...

Re: Anyone ever converted Torchmate to ballscrews?

Ballscrews likely will be heavier, potentially affecting inertia. Torchmates have tiny, undersized motors to start with, so this could cause issues.

Re: Water wicking is a fast problem

On the newer Hypertherm plasma's with a quick connect work cable you will see water at the fitting, and I suppose it could corr...

Re: Drill/tap steel after cutting

Dry cutting with air or nitrogen nitride (case) hardens the edge of most mild steels to a depth of .006" to .010". Cutting with water in contact with the edge can add hydrogen embrittlement as well. Industrial plasmas are designed with liquid cooled torches and special gas delivery systems...

It is not advisable to build a hood....as this implies that you are allowing the smoke/fume to rise out of the table and get pulled through the precision moving parts of your cnc cutting table. Plasma fumes/dust are small, hard, sharp pieces of the material you are cutting and will affect performanc...

Re: 1" plate cut. pm65 or oxy-fuel for best cut?

First, if you have to do any piercing, the Powermax65 is not recommended for piercing over 5/8". Piercing 1" with the 65 will destroy nozzles and shields rapidly. 8 inches per minute will be the cut speed, assuming you edge start (no damage to nozzle/shield) then expect about a 1 to 2 degr...

And on the other hand, I am a long time proponent of downdraft tables. When water contacts the cut edge it causes edge roughness and more chance of dross. Further, water on the surface of the material makes the ohmic sense process sense the surface of the water instead of the material....so pierce h...

I'm not sure I understand what settings you need. Typically with a THC you connect the arc transfer signal as a means of telling the system that the arc just transferred and started cutting the material. Hypertherm units measure current on the work lead, when current is sensed the relay across pins ...
