First thanks for this site it help a lot for learning our new hypertherm plasma. I've got a lot of questions by start with 2. The first one is about the amperage setting. A mechanic told my collegue that we always have to let the setting of the machine at 130 amp if it's a 130 amp machine. Is that breaking of dammaging the machine if I set it example AT 100 !
The second thing is to known if we can have only the little plastic ring going on top of the retaining cap. We change the retaining cap just for that. Only the ring break, the rest is fine. For me it is waisting piece and money. There is no number for that piece so I guess we have to order it all !
Thanks for your help. I'm sorry for the ortograph I am french in Quebec. And my question mark on the keyboard don't want to work so I put this ( ! ) instead .

Re: HPR 130 HD amp setting
Jean,
The HPR130 is a high definition class industrial plasma system.....it is very well engineered to provide the best quality on materials from gauge thickness to about 1". The best advice is to follow the cut charts (there are about 15 pages of them) in your operators manual exactly. Use the consumable parts listed at the top of the page, set the gases exactly as stated (or....if you have an auto gas system they will set automatically), set the pierce height, pierce delay, cut height, arc voltage , cut speed, and amperage just as the chart says.
If the cut chart says to use 130 amps on a specific material thickness.....and you choose to use a different amperage, then expect the cut quality to change.....as well as the consumable life. If you cut at less amperage than recommended...it reduces the energy density of the arc, which will change the cut edge angularity and will produce dross.
The HPR130 has consumables that are designed to fine tune cutting on a wide range of thickness. There are 30, 45, 50, 80 and 130 amp consumables. This allows you (using the recommended cut charts) to get the required cut quality on each material type and thickness.
I am assuming you are talking about the composite insulator on the inner retaining cap on your torch. These insulators are not replaceable as they are manufactured with the retaining cap for good concentricity. If you are having a lot of issues with the ring failing.....I suggest talking with your supplier to determine what may be going wrong.

Re: HPR 130 HD amp setting
Tthanks a lot for the information Jim. I read all the book we have each day a little bit at the time and there is a lot to learn. We cut a lot of aluminium and I find the good setting for it. The only thing we have to grind all the piece because the welders complain about contamanition. I'm a bit frustrated because the cuts are very straitgh and almost no dross at all. I can't do better than that. I'm very happy with that machine. We cut with air air, didn't try the gas yet. The other thing is we cut in a water table witch it will be modified to accept the gas cutting without explosion. And maybe the water contaminated the aluminium we cut. Because we are cutting more and more stainless the residu are going in the water. But that I'm notsure. Meanwhile I'm reading all comments on that site to learn more.
