Model family
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.

Control areas to separate
| Area | What it affects | Repair evidence |
|---|---|---|
| Conventional MIG base system | Gas, feeder motor, voltage output and torch command | Use normal MIG fault routing before blaming pulse control. |
| Pulse command section | Peak current, base current, frequency and duty selection | Pulse controls do not change arc behavior or display values. |
| Feedback loop | Current response and waveform regulation | Pulse becomes unstable, clipped or unable to follow settings. |
| Power-output stage | Actual current waveform delivered to the arc | Command appears normal but measured output or arc evidence is wrong. |
