Reliable Repair Parts for Hobart Excel-Arc Welders

Keep your industrial welding operations running smoothly with the Line Contactor for Excel-Arc 604 (Part #405402). The Excel-Arc series is known for its workhorse performance in heavy fabrication, but like all electromechanical equipment, internal components eventually require service. The line contactor is the heart of your welder's power engagement system, responsible for delivering current to the arc exactly when you need it.

When a contactor begins to fail, it can cause frustrating interruptions to your workflow. You might experience erratic arc starts, a welder that won't stop outputting power (a dangerous safety hazard), or complete failure to initiate an arc. This replacement contactor is engineered to solve these issues immediately. It is manufactured to the precise specifications required by the Excel-Arc 604, ensuring a perfect fit and reliable electrical connection without the need for modifications during installation.

Why Replace Your Contactor?

• Safety: A stuck contactor keeps the wire electrically hot, posing a shock hazard.
