Control Unit

Robot interface receives input signals for contactor control, gas control, jog, welding volts, and wire speed. It also receives a signal to initiate a check to see if wire is stuck to workpiece at end of a weld.

Robot interface sends output sig- nals to robot control unit for current sense, wire stuck, and weld stand- by.

Wire Feed Speed 0-10V = 0-1000 IPM

Output Volts 0-10V = 0-50V
