4.	A de-rust stainless lower guide arm to isolate the high temperature waer flow by air gap, can totally separate the heat transmission.

Pulse Control of Discharging Circuit

Employs a self-developed high speed discharging control chipest, featuring high calculation processing capability up to 100 mega-times per second. The control circuit provides instantly correct judgement and calculation processing for arious discharging conditions. Also, it automatically adjusts and controls discharging energy output for abnormal discharging waves. Machining efficiency can reach up to 180mm per min.

Controller Powerful 64 Bit CPU

The controller is a high speed, stable, industrial grade computer, featuring powerful NC calculation function for high accuracy machining. Comprehensive on-line HELP information and user-friendly operational presents an extra powerful calculation feature on these new generations of functions based on a new generation pcbased control. No matter how complicated the machining job may be, the opertaor caneasily work out the desired product.

EF non-electrolytic of discharging circuit

High speed EF (non-electrolytic) discharge machining metod. It minimizes the possibility of work piece surface cracking or clectrolyzed problems, which greatly upgrades the mold discharging effects and saves copper wire consumption.

Intelligent OV Circuit

Specially designed intellent ignition control circuit permits ignition voltage, voltage adjustment and control by computer, and is excellent for machining various work piece materials, with both thick and thin sheet plates. Also a voltage stabilizing circuit maintains discharge machining at constantly high speeds and 20%, especially when working on particularly thick or think work piece.

Modulay Design

The circuit board is a modular design. Each module interface features self-siagnostic output combined with signal indications This simplifies trouble-shooting and provides convenience in maintenance.

Super Fine Loop

The super fine loop employs a high frequency, non-electrolytic machining method. The process combines high stabiliy wire feeding tension control. All of which fabricates and extremely fine work piece surface.

Detailed Operation Instructions, Machining Information and Warning Messages for Readily Controlling Machining Conditions

The operational screen provides large quantities of graphic desceiptions, on-line HELP, warning descriptions, detailed operation instructions and message. This enable the operator to understand the current machine condition, so that the machining result can be easily controlled.
**Simply input the wire diameter, work piece material / thickness, and surface roughness required, then the corresponding machining conditions are automatically called out from the machining databank.
