Hypertherm 45 for marking.

Postby bisonsolar » Wed Mar 06, 2013 11:07 am

I went to cut some parts yesterday and forgot to hook the ground clamp.
The Hypertherm 45 made a really nice "etch" of the part.
Im wondering if I can use the hypertherm for marking like this?
Will ut hurt the machine or eat consumables?

Jim if your out there, please chime in.

A new machine should also come with gouging nozzle 220672 and gouging shield 220675, have a play with them. Handy for marking a design into a sheet for a different effect.

Etching the plate without the ground clamp on the cutting bed is ultimately going to cause a high current flow from the plasma through some of your machine drive electronics. You are asking for a fried drive board or drive motor. If you want to "etch"( known as "arc writing") you simply turn the power down to minimum and set the cut speed as fast as the machine can move with any level of accuracy. You could also use argon (instead of air) for a lighter mark.

Our high end industrial systems can switch automatically from cutting at high current to marking (using argon and nitrogen) at about 10 to 15 amps.

How will low setting work with a auto height control? I have a torchmate "blue screen" height control?

Using the AVHC with the plasma set on the lowest amperage setting should work fine. You will have to experiment with the voltage setting to get the height where it works best for marking. Lower voltage equals lower height.

Jim,
Isn't that supposed to be hard on nozzles when it's moving and the torch isn't blowing through. Someone, maybe Pcam folks or your people, once told me the nozzle orifice becomes elongated if the torch starts moving before it has pierced. ???

By the way, I really enjoyed your latest webinar.

No, It will not hurt the nozzle any more than regular cutting, especially at minimum amperage.
