 MS-150-C General Purpose Unit


AC and DC output with 6-position switch.

Settings A through F regulate the marking voltage, ranging from 5 volts progressively through 8 volts, 11volts, 14 volts, 17 volts and ultimately 20 volts on the F setting.

Electrolytic Stencil Cleaning Current is available through the yellow output jack. When connected to a cleaning tray it serves as an effective method of removing a build up of oxide out of the open aperture of fabric stencils as to improve marking quality and extend stencil life. Additionally, if the Black (Monode) lead is moved to the Yellow output jack a high output side of the transformer is activated that will provide DEEP ETCH results to approx .003” depth below the surface.

MS-311 Deep Etch Unit


Ideal for Grid Marking or DEEP ETCH applications

AC and DC output with a 6-position selector switch.

Settings A through F regulate the marking voltage, ranging from 5 volts progressively through 8 volts, 11 volts, 14 volts, 17 volts and ultimately 20 volts on the F setting when on the LOW setting. This heavy duty unit can be switch to a HIGH range that doubles the voltages on all settings to a maximum or 40 volts. Best suited for manual production marking where more power is needed for extreme depth. This unit will accommodate surface marking requirements from 0.0001” to more aggressive marking of 0.006” below the surface

MS311 Deep Etch Power Unit

MS-400-CC Automated Series


AC and DC output with 6-position switch. Voltage ranging from 5 volts progressively through 8 volts, 11 volts, 14 volts, 17 volts and ultimately 20 volts. The pulsing current generated by this unit results in a cleaner extraction of material and deeper results. The EPC feature (Electronic Pulse Control) and the cycle timers have proven effective for consistent depth and quality from part to part and greatly extends the life of Fabric Stencils. This unit is equipped with the necessary circuitry to support the AM-10-A and AM-30-T semi and fully automated etching systems.
