0193358102 - ESAB LAF 1000/1001 Replacement Contactor

Get Your LAF Power Source Back Online

If your ESAB LAF 1000 or LAF 1001 submerged arc welder is acting up, the contactor is often a prime suspect. These machines are the workhorses of heavy fabrication, running high amperages for extended periods. Over time, the mechanical contacts inside the switch can wear down, pit, or even weld themselves shut due to the intense electrical arcs they manage. When this happens, you might experience issues like the machine refusing to start, power not cutting off when the trigger is released, or erratic power delivery. The ESAB 0193358102 Contactor is the direct, genuine replacement you need to fix these issues and get back to production.

Don't risk your expensive equipment with generic electrical parts that might not handle the load. This contactor is built by ESAB specifically for the LAF series. It handles the heavy lifting of switching the massive power required for submerged arc welding. Installing the correct part means you won't have to worry about it failing in the middle of a critical pass on a pressure vessel or bridge beam. It fits exactly where the old one comes out, meaning you won't be fighting with mounting holes or trying to rig up adapters for your wiring connections.

Replacing a contactor is a standard maintenance procedure for aging welding power sources. Symptoms of a failing contactor often include a loud buzzing or humming noise coming from the machine cabinet, or a delay between hitting the start button and the arc actually establishing. If you are noticing these signs, it is smart to swap the part out before it fails completely and halts your line. Keep your shop running smoothly and safely with this authentic ESAB replacement part.

Safety Note: Replacing internal electrical components like this contactor involves working inside the power source cabinet where high voltages are present. Always ensure the machine is completely disconnected from input power (Lockout/Tagout) and that capacitors are discharged before attempting any repairs. If you aren't comfortable with industrial electrical work, please consult a qualified technician.
