I have the crossfire pro and always add .5 sec to my pierce delay (thanks to info found on here). That has worked great for 14g and 16g material. When reading other topics on this subject, I get a bit confused on where I should set when cutting material that already has a pierce delay greater than the suggested .5. Should I continue to add the full .5 sec on 3/8” and 1/2” material, or back it off a bit?
The manual suggests .7 for 3/8 and 1.2 for half.
I am limited on this thicker material, so I have little room for error or testing.
Thank you in advance.
I have a non sync 65. I never really add to my piercings delay above .5 it won’t hurt to add a little to it even adding .5 won’t hurt I don’t believe. I think it is more critical to make sure the pierce height is right. I am not sure about the sync model but the non sync calls for a little bit higher pierce height than for thin material. Then also make sure you use a decent lead in I try to use a long lead in on thick material. In the end you want to make sure your particular machine is piercing through the material before it moves.
Can you go to local scrap yard to find test cut material? Most places I have been will sell to you pretty cheap.
Thank you. I just dug around and found a scrap piece of 3/8. Im gonna play with it and try to dial in before cutting the half. Will keep the board posted.

You can even do a small piece and edit your code so all it will do is pierce. That way you can test your piercing in scrap parts of your cut.
I also found with mine it is best to slow down 20 percent pre hypertherm… I can’t say that for the sync model. Their speed was developed on a downdraft table.
Ok, Got it done. Started with .35 as suggested by ChelanJim, in another thread. Was not quite enough. The .5 additional worked great on both 1/4 and 1/2”. I also add .5 for all my small stuff (14g and 16g) for anyone curious.
