Looking to get a 45xp to put on a Bulltear table with candcnc controls to replace older hypertherm unit. Candcnc indicate I should ensure plasma unit has rs485. It appears the hypertherm pn 088119 is the right one, if I'm reading the chart correctly it's 220v, 25' machine torch, cpc port plus "serial" which I assume is rs485. 088116 has same description but no mention of serial. Has anyone bought the 008119 and confirm this? I'll also have to purchase the candcnc advanced connection kit.
