Pulse MIG / MAG Welders

A WelderData model-family hub for pulse gas-shielded wire-feed welders, linking waveform control, pulse-mode fault routing and conventional MIG/MAG feeder diagnosis.

Database summary

Pulse MIG/MAG welders extend the conventional constant-voltage wire-feed platform by adding a controlled current or power pulse pattern. The machine must still coordinate torch command, gas, feeder motor and voltage output, but it also needs a pulse command path that defines peak current, base current, frequency and duty ratio.

WelderData separates pulse-mode faults from ordinary MIG faults. If gas, wire feed and basic output are normal but the pulse action is missing, unstable or fixed, the diagnosis moves toward pulse setting, waveform generation, feedback and output-control sections.
