The ESAB 0349305837 is a specialized Potentiometer and Switch assembly (RP2) designed specifically for the maintenance and repair of ESAB Multimaster welding machines. This component is critical for the accurate regulation of electrical parameters within the power source. Rated at 470K Ohms, this potentiometer provides the specific resistance curve required by the Multimaster 173 and Multimaster 203 control boards to function correctly. Using non-OEM components with incorrect resistance values can lead to calibration errors, inability to reach maximum or minimum settings, or potential damage to the control PCB.
This unit integrates both the variable resistor (potentiometer) and a switching mechanism, often used to combine on/off functionality with parameter adjustment or to trigger specific circuit modes. As an original equipment manufacturer (OEM) part, it guarantees physical fitment into the machine's front panel or internal mounting points without modification. The shaft length, diameter, and terminal configuration are engineered to match the original factory specifications of the Multimaster series.
Technicians repairing older ESAB units will find this part essential for resolving issues related to dead spots in control dials, erratic output where the welding arc fluctuates unexpectedly, or total failure of the specific control function. Maintaining the integrity of your welding equipment with genuine ESAB parts ensures longevity and reliability in industrial environments.
