Superior height control |
|
• The system will respond to arc voltage changes of less than 1 volt. |
| • Maximum speed of retract exceeds 200 ipm (5.0 m/min) |
| • Built-in Ohmic touch-retract initial height sensing (IHS) feature ensures accurate, repeatable initial piercing height settings. |
| • A work-clear feature senses the loss of Ohmic contract for accurate positioning, even on thin, flexible sheet metal. |
| • Built-in motor-stall IHA 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. |
| • Rapid pull-back feature moves the torch away from the workpiece if a touch is detected during cutting.* This collision avoidance feature will prevent crashes such as workpieces that tip up or buckle. |
| • CNC-controlled arc voltage control can be disabled during cornering to keep the torch from diving at corners. |
| • Over-voltage protection automatically eliminates "torch diving" during large, out of-limits arc voltage fluctuations; such as kerf crossings or cutting off the edge of a plate.* |
| • Built-in, advance preflow reduces cycle time by allowing gas to preflow during the IHS cycle. |
| • Optimal breakaway is designed to reduce or eliminate damage to the torch due to accidental collisions in all axis. |
