What are you using for Voltage in your THC settings…SmartVoltage or a Nominal Voltage setting? If you are using Nominal Voltage the torch would raise after a misfire event which could explain what you are seeing there. Can you get a video of this?
As for your misfire problem I see you are using a Razorweld 45…have you seen this tech bulletin from them? RAZORCUT45 Misfire Issue - RAZORWELD TECH BULLETIN 9/23/2020
