The Model 500 "Controller" Power Unit. The Model 500 is the most powerful and controllable etching machine available on the market. It’s variable output voltage (0-40 ), low impedance, high power (500 watts), SCR phase control circuitry , integral electronic timer and pulser allows etch rates and depths of etch to be controlled with a high degree of precision. Depths of etch up to 0.010” can easily be achieved and can be accurately controlled to within +/- 0.0005” . This machine is especially suited to aerospace applications where precise depth of etch is a requirement by specifications. It is approved by most major aerospace corporations’ specs.

The Model 200 "Supervisor" Power Unit. The Model 200 has the same power, output voltage, and low impedance SCR phase control circuitry as the Model 500, except that it does not have the internal timer and pulser. It is more suited to manual applications. Depts of etch up to 0.010" are also easily achievable with this machine.

The Model 100 "producer" Power Unit. The Model 100 is the smaller cousin of the 200. It has 100 watts of power and variable output voltage of up to 24 volts. This general purpose machine has plenty of power for most applications and is in use in machine shops, medical instruments and cutlery industries. This machine has earned a fine reputation for its modest price, capability, and reliability.
