0193444102 - ESAB EH100 42V Contactor for LAE 800 Power Source

Reliable Power Switching for Industrial Welding

The ESAB EH100 Contactor (42V), identified by SKU 0193444102, is a critical replacement component designed specifically for the ESAB LAE 800 welding power source. In the realm of heavy industrial welding, the contactor serves as the primary gateway for welding current, engaging and disengaging the high-power output based on the trigger signal. The EH100 model is renowned for its durability and ability to handle the rigorous electrical loads associated with high-amperage welding operations.

This specific unit features a 42V coil, which is the standard control voltage for the LAE 800 series. Using a contactor with the correct coil voltage is paramount; an incorrect voltage can lead to coil burnout or failure to engage. As a genuine ESAB OEM part, this contactor guarantees seamless integration with your existing machine's internal wiring and mounting points, eliminating the need for retrofitting or modifications often required by aftermarket generic parts.

Maintenance professionals understand that the contactor is a wear item. Over thousands of cycles, the internal contacts can become pitted or carbonized, leading to increased resistance, voltage drop, and eventually, a machine that powers on but refuses to weld. Replacing a failing unit with this authentic EH100 contactor ensures that your LAE 800 continues to operate at peak efficiency, delivering the stable arc characteristics that ESAB equipment is known for. Whether you are performing preventative maintenance or an emergency repair, this component provides the reliability required in professional fabrication environments.

The construction of the EH100 includes high-grade materials designed to dissipate heat effectively and resist mechanical shock. This ensures a long service life even in environments with high vibration or fluctuating temperatures. By choosing the correct OEM part, you protect the downstream components of your welding machine and ensure safety for the operator.
