After doing some testing with @oneupperformance it’s clear that the Everlast Powerplasma machines (maybe not all but certainly some?) are not outputting the advertised 50:1 divided voltage at their CNC ports. The divided port seems to be closer to something like 100:1. What this means is that the displayed ‘Live Voltage’ in FireControl is not representative of the actual arc voltage. The LS-THC unit and software were designed around a 50:1 setup for optimal performance. While it is possible to cut using this port even without accurate voltage information being displayed, we haven’t done enough testing at this divided output to understand what the sweet spot is for all the LS-THC settings in FireControl. Andy was able to get some good cuts on an inclined plate once he did some basic line tests for determining the ideal Nominal Voltage for his plate thickness/cut speed and tweaking some settings, but features like SmartVoltage we’rent working as well. We are disappointed that the Everlast Powerplasma machines don’t seem to be outputting the correct voltage as advertised, but we are here to figure out the best solution for our customers!
Our goal is to do additional testing at a divided voltage of 100:1 to determine if we can come up with some better stock settings for the Everlast folks. We will be working on these the next couple of days and will have some updates soon.
The good news is that anyone with an Everlast cutter has the option of wiring up their LS-THC for Raw Voltage instead if they would rather have optimal performance and the correct actual voltage being used. The CNC port on the Everlast machines fortunately have output pins for raw voltage (pins 5 and 7) that can be wired up to the supplied Raw Voltage Pigtail Cables (red and black banana connector cables with bare wires) that came with the LS-THC units. As always, please make sure that you are following our User Guide for this step as high voltage can be lethal if not installed properly!
