Proma 150 THC 45XP fine cut problem

Post by Dirtmotor »

Having a problem .
The THC works perfect with the hypertherm normal consumables , But when I try to use the fine cuts torch moves up while cutting till I hit stop . Have played with everything I know to fix . No change . This is a premier plasma table and using hypertherm 45xp , using sheetcam to mach 3 , can someone help ? Thanks

Did you look at the chart for the correct arc voltage for fine cut and metal thickness. It is different than a 45 amp nozzle.

Thanks , I have not lowered voltage as much as chart says, usually bad things happen when I change voltage that much . currently cutting at 99 volts book says 78 , I will try and see what happens .

Don't be hesitant to change that arc voltage, you can always got back and the chart numbers are good starting points but not gospel.

Here is a video on how to find the correct voltage for each material you cut. This was for a Price THC but is the same for all THC units. Run the tests and create your own list for your unit.
