Re: PM45 Cut Quality

The holes actually should never get plugged. When pierce height and pierce delay times are set right....no material will hit the part of the shield where the vent holes are. The stuff plugging the holes is usually steel, which does not stick to copper. I suggest picking the material out with a denta...

Re: PM45 Cut Quality

The nozzle is severely cratered on the arc exit side...this indicates that the pilot arc is staying on too long which is most often caused by having the mode switch in the "expanded metal"cutting position, but can also be caused by the pierce height being too high or pierce delay being too...

Re: Cutting 1/4 inch steel with Finecut Nozzle

You can get good cuts with Finecut on materials thicker than they are rated for, which is a maximum of 10 gauge. Expect very short nozzle life if you want to cut thicker than 10 gauge as these consumables are not designed to pierce thicker materiasl...and the nozzle orifice will erode rather quickly...

Re: Bevel issue made me punch my kids in the face!

There is a small amount of air that is supposed to exit above the retaining cap on some Hypertherm air torches....it is for torch body and retaining cap cooling.

Re: Ideas on Cutting Stainless

If you have a Hypertherm, use the Finecut consumables, make sure your height control works, and follow the cut specs in the manual. Cut height and cut speeds.....if you follow the specs, will minimize warping and provide a good quality edge. I just cut out a 20 gauge stainless steel Kitchen hood usi...

Re: PM65 Shield Clearance

Use the 220955 defelector instead of the 220948 shield.....this will provide more clearance, but you will not be able to use Ohmic surface sensing.

Re: What to do with scraps-Ideas?

lizards of all sizes. A local art store and garden shop buy them by the dozens. Just scale them, paste them on your material between cuts to use up steel. the smallest sell for a dollar (about one pennies worth of steel). Jim Colt Hypertherm

Re: Bevel issue made me punch my kids in the face!

A bad o-ring does not knock anything out of alignment.....what it does is that it changes the critical shield gas pressure / flow. Having a damaged shield orifice, plugged shield vent holes or a damaged retaining cap will do the same thing. By changing the shield flow....it can also affect the cut f...

Re: Corner slowdown rules...do you use them for art, or just dimensional stuff?

The whole idea for slowing on holes is to allow the bottom of the plasma arc to "catch up" with the top of the arc.....at ideal, dross free cutting speeds when using air as the plasma gas...there will be a 5 to 15 degree (depending on material thickness and consumables and torch model) lag...
