ARCPro THC Parameters

Post by ChrisO » Tue Jan 11, 2022 12:26 pm

Anyone have experience they can share on setting up the Parameters for THC? I just got a Plasma table retrofitted with Vital Systems ArcPro system and I am currently using trial and error approach to create the data in the THC Parameters table. Currently I am turning THC off, setting the torch height IAW Plasma Manufacture spec, run a 5" long cut and incrementing the speed by 5ipm. After about 6 cuts, I then inspect my cut. I am currently working on 1/4" steel.
Perhaps someone has done this before and can share some insight on a better way to do this? Below are the data I am trying to capture. Perhaps someone has Vital Systems ArcPro and can share their Parameters?

Deadband Volts
Adjust Speed(%)
FR AntiDive(%)
Tip Volt Operating Range(%)
TV Rec Range (%)
Torch On Height
ArcOK Timeout (ms)
Pierce Height
Pierce Delay(ms)
Cut Height
Max Cut Height
Min Cut Height
THC Delay(ms)
Tool number
Description(material)

Hey Chris, not familiar with Arcpro. Maybe if you were to post back the values you are currently using for those parameters and post the issues you have with using those settings someone may be able to get you closer.

Hey thanks, I will post back results of tests as you suggested.. but it might be awhile as a problem just came up. The Plasma cutter has a problem as it does not turn itself off after the cut. (initial investigations are pointing to the plasma cutters Logic Control PCB board.) I'll get back to THC Parameters after I have resolved this new issue.

If its not turning off, its possible you have the wrong setting on the plasma cutter itself. Some can be set to come on with a button press and turned off with a second button press. Do not use this mode for CNC plasma!

A lot of your settings are plasma cutter make and model specific. Some would be for all materials, others will also change with material type and thickness. If you do not have cutcharts, you need to do what you are doing for each thickness.
