Lotos LTP5500D CNC Cut Chart

Tom, do I need to use the 4-pin input on the LTP5500DCNC unit? Or, do I just use the 2-pin input?

It seems the latest version uses the 2-pin connector for torch on/off control

Yes, I use the 2pin connector for Torch On/Off. Polarity doesn’t matter.

yes it will work 5500 you have to tap in to gun control firing pin its not a high frequency machine will not mess with CNC controller.
