D12000 Air Cutting Plasma System

Capable of clean cutting nearly 2-inch carbon steel and aluminum alloys, the D-12000 is a safe and economical alternative to Oxy-fuel cutting.  It offers more unique, user-friendly features than any machine in its class.


The D-12000’s built-in water circulator provides very efficient cooling of the torch head, and circulates water directly inside the electrode for extended consumable life. Compressed air is used for cutting and cooling the torch, thereby eliminating the need for expensive gases.


Upon turning on the power source a self-diagnosis function takes place that will not allow the system to operate if an abnormal condition exist.  Indicator lamps
identify operational problems. Alarms will sound when unsafe conditions happen such as removing torch consumables with control power on.


Our patented “TORCH GUARD” feature monitors electrode consumption and indicates replacement time avoiding torch head damage from over use of the


The D-12000 can be setup for both semi-automatic (manual) use, as well as integrated with our FD, AII and ALMEGA AX Series Arc Welding Robots. (Integration to a robot requires an external interface supplied by OTC DAIHEN)
