SECTION 4 – OPERATION 4-1. Operational Terms The following is a list of terms and their definitions as they apply to this interface unit: General Terms: Adaptive Pulse Welding When the “adaptive pulse” welding process is selected, the unit will attempt to automatically regulate pulse frequency in order to maintain a constant arc length, regardless of change in welding wire stick- out.
System Reset By selecting system reset in the memory reset mode, the unit defaults to original factory settings for all programs and all set up excluding System, Arc Time, and Model Type. Voltage (Control Feedback) Allows voltage to be monitored at the output terminals by two methods. This can be selected through the internal connections of the unit, or through the unit’s external voltage sense lead.
