Features of the THC-A2 - Arc Voltage Control, 50-280 volts, fully automatic, continuously making fine adjustments throughout the cutting process. - Max. 200 mm active stroke (vertical torch travel). - Speed of retract exteeds 150 mm/sec - Max. adjustment speed 30 mm/sec. - Max. load 3,5 kg. - Weight 2 kg. - Supply voltage 24 VDC (Max. 2A) - Built-in Ohmic touch-retract initial height sensing (IHS ¹) feature ensures accurate repeatable initial piercing height settings. - Pierce height setting from 1 to 25 mm, in 1 mm increments. - Built-in stall IHS feature is always active and serves as a back-up for the Ohmic IHS. When cutting non-conductive material surfaces, such as painted plate or underwater cutting. - At the beginning of cutting start make arc voltage controlled adjustments after first “freeze” (first X-Y acceleration) or after delay 0,7 sec (in case when CNC control don’t have “edge freeze output). -Collision control. Breakaway is designed to reduce or eliminate damage to the torch due to accidental collision. - Upper and lower travel-limit stops. Upper could be set (O-ring on the belt). - Compatible with most plasma power supplies, with steady operating current and witch all machine torches. Also compatible with fine plasma. - Independent of the systems electronics, and only require a computer controlled output in minimal hook up.. - Manually up and down buttons, - HV/HF ignition resistant. Controller is 100% galvanic isolated (including analogue arc voltage signal). - Dustproof, simple, robust and rigid mechanic allows for easy maintenance and repair. - THC-A2 units are easy to install. 5
