Does MASSO include a built-in THC?

No, MASSO does not include a built-in Torch Height Controller (THC). However, you can use the MASSO DTHC, which is specifically designed to integrate with MASSO.

The MASSO DTHC requires a plasma source with a built-in voltage divider.

Does MASSO supply a THC to use with MASSO?

Yes, the MASSO DTHC is designed specifically to work with MASSO G3 and MASSO Touch controllers.

Can I use third-party THCs with MASSO?

Yes, MASSO supports third-party THCs that provide UP, DOWN, and ARC OK signals.

Any THC capable of outputting these signals can be used with MASSO, including systems such as the Proma 150 or Price AVHC.

How do I turn the plasma on and off with MASSO?

The plasma is controlled using a designated Plasma On/Off output.

You can configure any MASSO G3 TTL output as the Plasma On/Off signal and connect it to your plasma source using the MASSO Relay Module.

What equipment do I need to convert or build a plasma CNC machine?

To determine your requirements, start by creating an inventory of what your machine already has and what additional components you need.
