Multiquip 8702631004 Solenoid Arm

The Multiquip 8702631004 Solenoid Arm is a genuine OEM component designed for DLW300ES, ESA, and ESA1 series diesel light welders. Sourced directly from Multiquip, this part meets the exact specifications of the original assembly, ensuring a correct fit without guesswork. If your welder is experiencing issues with solenoid engagement or actuation, replacing the arm with the OEM 8702631004 restores proper electrical and mechanical function to the system.

Key Features

• Genuine OEM Actuation Geometry — Manufactured to the exact pivot dimensions and travel arc of the original solenoid arm, ensuring consistent engagement force and stroke across the full operating range.
• Direct Drop-In Replacement — Mounts to the existing solenoid assembly using the original hardware and attachment points, eliminating the need for fitment adjustments during installation.
• Confirmed Fitment for DLW300ES Series — Verified for DLW300ES, ESA, and ESA1 diesel light welder models, so you can order with confidence knowing this is the right part for your machine.
• Restores Reliable Solenoid Response — A worn or bent solenoid arm causes sluggish, incomplete, or failed solenoid actuation; replacing it returns precise, consistent response to every trigger cycle.
• Electrical Safety Compliance — As a component in the welder's electrical control circuit, using the correct OEM arm maintains proper solenoid alignment and helps prevent unintended arcing or control failure.

The solenoid arm is a mechanical linkage component that transfers movement from the solenoid body to the controlled mechanism — whether that is a fuel shutoff, throttle, or electrical contactor — within the welder's control system. When the solenoid is energized, the arm pivots or extends to actuate the target component; when de-energized, it returns to its rest position. A damaged, bent, or worn arm compromises this movement, leading to delayed response, incomplete actuation, or total failure of the function the solenoid controls, which can prevent the machine from starting, running, or shutting down correctly.
