0193502105 - ESAB Aristo Replacement Contactor LC1D3210Q7 380V Coil

Genuine ESAB Replacement Contactor for Aristo Welders

The ESAB 0193502105 Contactor is a critical electrical component designed for specific ESAB industrial welding power sources, particularly within the Aristo product line. Manufactured to the highest standards by Schneider Electric (Telemecanique) under the model number LC1D3210Q7, this contactor serves as the main power switch for the welding transformer or inverter stages, handling the high-current demands of heavy-duty welding operations.

This 3-pole contactor is rated for 32 Amps (AC-3 utilization category) and features a 380V AC control coil (indicated by the 'Q7' suffix). It is essential to verify that your machine's control circuit voltage matches this specification before installation, as using a contactor with an incorrect coil voltage can lead to immediate component failure or non-operation. The unit includes three main power poles (Normally Open) and one auxiliary contact (Normally Open) for control feedback integration.

When a welding machine's contactor begins to fail, operators may notice symptoms such as the machine refusing to strike an arc, a loud buzzing noise coming from the power source, or the machine staying 'on' even when the trigger is released (if contacts weld shut). Replacing a faulty contactor with this genuine ESAB spare ensures that your equipment retains its original safety ratings and performance characteristics. The device mounts easily via standard DIN rail or panel screws and utilizes robust screw clamp terminals for secure, vibration-resistant electrical connections.
