THC-A2 Automatic Torch Height Control for Mechanized Plasma ...

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.
