950256 - ESAB 0.002uF 10kV Mica Capacitor for HF Units

Restore Reliable Arc Starting to Your Welder

Is your TIG welder or plasma cutter struggling to start an arc? Do you find yourself having to scratch the tungsten to get going, even when the machine is set to High-Frequency start? The culprit is often a small but critical component inside your machine: the high-voltage capacitor. The ESAB 950256 Mica Capacitor (0.002 µF, 10kV) is a heavy-duty replacement part designed to bring your equipment back to life. This capacitor acts as a key element in the High-Frequency (HF) unit, storing and releasing the energy needed to jump the gap and establish a clean, stable welding arc without contact.

Welding machines are tough, but the internal electronics are subjected to massive electrical stresses every time you pull the trigger. Over time, the original capacitors can wear out, dry up, or short circuit, leading to weak sparks or a completely dead HF system. This replacement unit is built with high-quality Mica, a material known for its incredible durability and ability to handle the 10,000-volt surges required for industrial arc starting. Unlike cheaper generic capacitors that might burn out after a few weeks, this part is engineered to withstand the heat and electrical load of a busy fabrication shop.

Replacing a faulty capacitor can save you the cost of a brand-new machine or an expensive service call. If you are comfortable working with electronics and discharging capacitors safely, swapping out this part is a straightforward repair that can instantly fix "hard starting" issues. When your HF start works correctly, you save time, reduce tungsten contamination, and produce higher-quality welds. Don't let a small electrical gremlin slow down your production; trust this genuine-spec component to restore the snap and reliability you expect from your ESAB equipment.

Please note: This component is rated for 10,000 volts. Always ensure the machine is unplugged and capacitors are properly discharged before attempting any internal repairs. This part is compatible with specific ESAB models requiring a 0.002 µF, 10KWV mica capacitor. Check your machine's parts diagram or the markings on your old capacitor to ensure a perfect match.
