25A with a PM85A

[Geanvert]

hello everyone, I just saw that my PM85 is capable of going down to 25A, what can we do with this power knowing that there is no nozzle below 45A for this model? THANKS

You can cut at lower amps with a 45a nozzle. Works good on thin material.

What material thickness are you cutting?

[Geanvert]

I intended to cut 1mm for decorative logos.

For that thickness I would use a Finecut nozzle and do some test cuts at say 45, 35, and 25 amps at the correct cutting height and appropriate speed see what is producing the best results. The biggest advantage I could see using lower amps is it would allow you to cut at a slower speed which is good for machines that get sloppy and/or don't like higher cut speeds. If your machine can handle the speed it needs to cut at 45 amps it should produce great results without turning the amps down.
