Sourced directly through Multiquip's authorized parts network, the 0602100310 is the correct replacement for DLW330X2 and DLW400ESA4 operators who need an exact-match key for their ignition system.

Key Features
- Genuine OEM Ignition Match — Cut and coded to the exact ignition cylinder profile used on Multiquip diesel light welder models, so the key engages cleanly and operates the switch as intended.
- Direct-Fit Replacement — Slots into the OEM ignition switch housing on DLW330X2 and DLW400ESA4 welders without modification to the switch or key barrel.
- Confirmed Fitment — Verified for DLW400ESA4 and DLW330X2 Multiquip diesel light welder models.
- Ignition System Integrity — A worn, damaged, or lost ignition key can prevent startup entirely or cause intermittent switch contact issues; replacing with the correct OEM key restores reliable ignition engagement.
- Operator Safety Compliance — Using the correct keyed ignition component is essential for maintaining proper machine lockout and access control on powered welder equipment.
The ignition key is the operator's primary interface with the machine's ignition switch, engaging the internal contacts that control the start, run, and stop positions of the welder's electrical system. On diesel light welders like the DLW330X2 and DLW400ESA4, a correctly fitted key ensures the switch cycles through each position fully and without binding, allowing reliable engine startup and controlled shutdown. A missing, worn, or incorrect key can prevent the machine from starting at all, or cause the switch contacts to engage incompletely — leading to starting failures or unintended electrical behavior.
