Torch Height Control and why you need it!
Torch Height Control (THC) is a device, sometimes integrated into the machine control itself, that measures the arc voltage of the cut while cutting. By measuring this voltage in real time we can determine if the torch is too far away from the work piece or too close too the work piece and make adjustments in real-time as necessary to maintain optimal torch height. This is important for many factors, all of which directly affect cut quality and precision. Probably the two most common issues that THC overcomes is work piece perpendicularity of the Z axis and work warping (Common on small materials, especially thin aluminum sheet). Maintaining optimal torch height at all times will increase consumable life, create a straight edge without bevel, and increase process reliability!
