Is your ESAB welder acting up or refusing to strike an arc? It might be time to check the internal electronics. The ESAB 0440277880 Gate Drive Board is a genuine replacement part designed to fix specific ESAB inverter machines. The gate drive board is the "muscle" behind the "brain" of your welder—it takes signals from the control panel and tells the heavy-duty power parts when to fire.
