Hey guys I had a question related to Hypertherm Powermax45 nozzles. I am currently getting my nozzles from a welding supply store in town who sells "American Torch Tip" brand. I noticedthe other day the the nozzles I am getting look nothing like the ones listed on the hypertherm page for the powermax 45 series. The part number I am ordering for the nozzle is correct (#220671). The ones I have been getting look like the ones used on a shielded powermax 1250 cutter. I could be wrong, but I am thinking American Torch tip is miss-packaging these nozzles wrong. The bag even says "Nozzle, PMX45" on it. I have bought 5 bags that have 5 nozles each, andonly one of these bags had the correct looking nozzles that look right for the powermax45. I never noticed until I pulled out all my old burned up nozzles becuase Ive been experiencing a ton of nozzle failures now Im wondering if I have been using the wrong nozzles the entire time.:shaking: I noticed the shaping of the pointof the nozzle is very different. Could this be why I am experiencing a ton of nozzle blowouts?

This what they should look like per hypertherm's site:


And the ones I have been getting look like this...They all have that nipple looking tip vs the rounded/tapered nozzle on pictured above. The nozzle failure have all been from the side of that long nipple portion blowing out.

Can't tell you if those are the right ones for your machine, but do yourself a favor and buy hypertherm consumables. We've tried several knockoffs and they don't last half as long.

Yeah, I going to do that..these arent lasting 10mins anyways..lol..Im just really trying to figure out if this nozzle design is my major issue and thats where the failures are coming from, or if I have another issue going on with my table like pierceing too close or something.

No...it will be cutting and then just eat the nozzle out..like its a heat issue..These nozzles look like they are for the 1250 cutter which would be 40 Amps and Ive been cutting at 45 Amps on my powermax45 I just never noticed I wasgetting the nozzles that look like the 1250 style till tonight.

A tip should last for atleast 20 hours...
Unless your friends use them......

Then count on replacing every consumable and the melted handle from god knows what the fuck they did with it...

I called hypertherm and it looks like the nozzle is not design for the powermax 45 torch. The didnt give me much "tech" beyond that and I already figured that much out myself. Im taking the old consumables back to the original store so they can do a follow up with thier vendor and see where the issue is. My machine cut well with the nozzle, but if it is in fact the wrong one then I was cutting at 5 Amps over the recomended rating of the nozzle. It had to have had an effect on the nozzle failure if that is the case.

I contacted Jim Colt aswell and asked him to comment. I just wanted to know what the "technical" difference in the nozzle designs are between the 2 machines and see if that info has anything to do with the issues I am experiencing. Or if there are some other issues I need to look at more closely on my setup. Thanks

It wouldn't surprise me if American Torch Tip fucked something up. I've worked very closely with one of their other companies and they didn't know their heads from their asses. I usually don't bad mouth anyone but I would buy elsewhere.

Yeah Im not suprised. I found a local vendor that carries the true hypertherm stuff so thats where I am going from here on out. Im talking to American's "Plasma Specialist" so we'll see how that goes.

Used the factory Hypertherm ones last night, night and day difference...these American torch tips label as PMX45 with the torch mate part number for the 45Amps nozzles are JUNK.

The Powermax45 nozzle is of a conical flow design, patented by Hypertherm. The shape works in conjunction with the inside shape of the shield to increase arc energy density and improve nozzle orifice cooling. These features improve edge squareness and increase nozzle life dramatically.

The upper picture you posted has the correct part number for a Powermax45 and looks correct to me. The bottom picture is of older technology nozzles as used on the older Powermax1000, 1250 and 1650 plasma systems.

American Torch Tip will be happy to sell you nozzles that will cut in a Powermax45, however they have to manufacture them without the conical flow features or they will infringe on current patents. You will lose life and performance...certainly not worth the savings. Further, incorrectly machined consumable parts can potentially damage the torch itself.

Thanks Jim, I appreciate the info. I could tell they were garbage as soon as I made my first few cuts last night with the real consumables. I didnt know I had a local Hypertherm vendor here in town, or I would have just ran them to begin with. Ive used them in my hand torch and they seem fine( but I dont cut much with it), but it went to crap quick in the machine torch with in about 3 minutes. I didnt know about the conical flow technology but it makes absolute sense to me know. Atleast i can inform others who might make my mistakes. Thanks!

I have ordered a lot of consumables from Hypermax online and had nothing but great service from them every time. There have been a few times that they have not had all of that parts but they called me to let me know what was going on and to find out if I wanted to have the ordered filled in two shipments. I have a couple local hypertherm vendors but they always seem to want to fuck around on getting things in quickly so I just go with the online guys and they show up at my door a few days later.

yeah, im running mine on a CNC setup so Im still working out my "setting kinks" to get optimal life out of them...Its getting there, but its time consuming and hard on them when your cutting wrong...Now, on my hand torch thats a different story...Those have lasted for a very long time..I too am very impressed with my powermax45..I recommend it to anyone I hear who is shopping for plasmas.
