OVERVIEW

Get Your Welder Back Up and Running

When your welding machine goes down, production stops, and that costs you money. If you've traced your machine's issue to a blown or failing capacitor, the ESAB 951998 is the exact replacement part you need to get back to burning rod. This isn't just any off-the-shelf electronic component; it is a genuine ESAB part designed specifically for the high-stress environment inside your welder. With a rating of 0.27µF and a massive 1200VDC, this capacitor is built to handle the heavy electrical loads and voltage spikes that occur every time you strike an arc.

Why does the voltage rating matter? Inside your welder, electricity is being transformed and manipulated to give you that smooth, stable arc you rely on. This process creates high-voltage surges that can fry lesser components. A 1200VDC rating means this capacitor is tough enough to sit in the heart of your machine's power supply and keep things running smoothly. Whether it's acting as a filter to clean up the power or a snubber to protect expensive transistors, this little part plays a huge role in how your machine performs.

Don't risk your expensive equipment with generic aftermarket parts that might not fit right or handle the heat. Using the correct OEM part like the 951998 ensures that the repair is done right the first time. It fits exactly where the old one came out, and it behaves exactly how the engineers intended. This peace of mind lets you focus on your welds, not on whether your machine is going to quit on you again in the middle of a job.

Safety Note: Replacing internal welder parts involves working with high voltage. Capacitors store electricity like a battery, even when the machine is unplugged. Always make sure the machine is disconnected from power and the capacitor is properly discharged before you touch it. If you aren't comfortable doing this, please consult a qualified repair technician. Keep your shop running and your welds clean with the right parts for the job.

FAQ

The capacitance value is 0.27 microfarads (µF).

This capacitor is rated for 1200 Volts DC (1200VDC).

While electrically possible, it is highly recommended to use the genuine ESAB OEM part to ensure physical fitment, terminal compatibility, and adherence to the specific thermal and durability standards of the welding machine.

Signs of a bad capacitor include physical bulging, leaking fluid, burn marks, or the machine failing to power up or maintain a stable arc. A multimeter with capacitance function can verify if it is out of spec.

Most high-voltage DC capacitors of this type are non-polarized film capacitors, but you should always check the markings on the casing and the circuit board for polarity indicators (+ and -) before installation.

Capacitors can store lethal voltage even when unplugged. Unless you are trained in high-voltage electronics discharge procedures, you should have a qualified technician install this part.

This part fits specific ESAB power sources. Please consult your machine's parts manual or contact ESAB support with your serial number to confirm compatibility.

Typically, capacitors are sold as the component only. You will usually reuse existing mounting brackets or screws unless specified otherwise.
