1. Application

• Dedicated arc welding (MIG/MAG/TIG) control on Motoman XRC cabinets.

• Interfaces the robot controller with analog welding power sources; outputs weld setpoints and inputs weld status.

2. Functions

• Analog outputs ×2：welding voltage, wire feed speed (or current).

• Welder status inputs ×4：gas fault, wire jam, arc ON, arc OFF.

• Welder control outputs ×4：arc start, wire feed, wire reverse, start detection (option).

• General‑purpose output ×1：for auxiliary devices.

3. Specifications

• Power：24 VDC ±10%；approx. 1.5 A.

• Fuses：F1 / F2, 1 A / 250 V, fast‑acting.
