Re: Piercing 3/8" thick plate

We upgraded the pierce capacity to 1/2" on the original Powermax45 about 6 or 7 years ago, unfortunately the spec in the operators manual did not get changed. Here is the cut chart for the 45 XP....these specs work perfectly with the original 45 up through 1/2". Jim Colt Hypertherm 45 amp ...

Re: Piercing 3/8" thick plate

The Powermax45 and 45 XP are both rated for straight in piercing up to 1/2" steel, when you follow book specs (pierce height, pierce delay time)...you will get a minimum of 300 pierces in 1/2" at the rated pierce thickness if you 100% follow the book specs, wiggle pierce is not recommended...

Re: Powermax 45 Air Flow Rates

It is exactly the same between post flow and test flow, both are higher in actual flow than it will be when cutting. Jim Colt

Re: Powermax 45 Air Flow Rates

When air flows without the plasma arc on...it actually flows slightly more air than when the arc is on. The arc heats and expands the air which causes somewhat of a restriction as the arc exits the nozzle orifice. Another way to flow the air is to trigger the torch quickly....too quick to fire the t...

Re: Cutting woven wire

If your plasma cutter has an expanded metal mode....switch it on and cut away. Have cut this many times with good results.

Re: What low amp/non book setting do you use for thin material?

Sorry Brand X, I must have had Powermax30 on my mind, not the XP....which is a totally different animal. I was talking you guys are making 30 amp nozzles for the 30 XP. Are those a step backwards too? I only ask because I had great results using the 20/30 amp consumables in my 30 amp Esab 400 (PT39 ...

Re: What low amp/non book setting do you use for thin material?

BrandX, It would be taking a step backwards to use the 30 amp T30 consumables as used with the original Powermax45. The Finecut parts used in the Powermax45XP (and the 65, 85 and 105) will cut with better quality, will cut at both slow and high speeds, and will last longer as compared to the old T30...

Re: What low amp/non book setting do you use for thin material?

As I've stated many times.....using lower amperage on a nozzle that is rated for a particular amperage (such as using finecut consumables with a 45 amp rating at 25 amps) reduces the energy density of the arc. Reducing the energy density decreases what we call the "Dross Free Interval", wh...

Re: Ohmic Sensor vs. Floating Head

Most high end industrial plasma systems use Ohmic as the primary surface sensing, and automatic switch to torque sensing or stall sensing (sensing a slight increase in z axis motor torque caused by contact with the material....stall is used with steppers, torque with servos). It is nice to have both...

Re: about to blow up my table and machine, need parts!

Speak with Wescott, determine what signals you need (Raw Arc voltage, Plasma start, Arc transfer) and I'll look at the schematics and help determine where to pick the signals from. The Powermax1100 was short lived, and was manufactured roughly 20 years ago.....so new parts such as an interface board...

Re: Machine torch question

Actually overtightening will not damage anything. What it will do is distort the swirl ring, which can cause a stuck consumables error code and misfiring. Just snug the cap and it is good! Jim Colt Hypertherm

Re: Piercing 3/8" thick plate

You should be able to pierce 3/8" all day without colliding with the pierce slag pile. My guess would be that your torch is staying in the pierce location too long (pierce delay time too long?) and the height control is activating too quickly. Here are a few suggestions: 1. Slow down your z axi...

Re: Ohmic Sensor vs. Floating Head

Ohmic sensing was first developed about 25 tears ago on high end industrial Plasma cnc machines. On all of these machines today it is the standard way of doing IHS (Initial Height Sensing), or finding the surface of the plate. Accurately locating the surface is key to correct pierce height, and on m...

As long as you regularly drain your air compressor tank.....and when doing so you don't see large amounts of water accumulating (say more than 1/4 cup or so after a busy day of cutting)...then the onboard particulate filter and coalescing separator on the Hypertherm Powermax units is adequate.

Re: All of a sudden consumables aren't lasting

In the gouging mode the ramp up amperage rate as well as the air pressure are different for use with the gouging nozzle. This will cause rapid nozzle orifice wear and poor cut quality when used with the cutting nozzle. In the expanded metal cutting mode.....the unit will rapidly switch back to pilot...

Re: 1/4" MS Cut w/ 45A Shielded - What am I doing wrong?

If you have the mode switch in the gouging mode or the expanded metal mode it could give these symptoms as the air pressure is lower in each mode as compared to the cutting mode. The nozzle picture is clearly junk....the orifice needs to be perfectly round. The notching is caused by piercing too clo...

I agree that the issue is pressure related. - replace the o-ring on your torch as a starting point and clean the torch well. -If you have not tried a new retaining cap...this can cause this issue. - With air flowing at the torch check the inlet pressure....with a gauge hard plumbed right on the inle...
