950358 - ESAB 1A 250V Time-Delay Replacement Fuse

Reliable Circuit Protection for ESAB Equipment

The ESAB 950358 Fuse is a critical electrical component designed specifically for compatible ESAB welding power sources and industrial equipment. Rated at 1.00 Amp and 250 Volts, this fuse utilizes a "Slo-Blo" or time-delay mechanism. Unlike fast-acting fuses that sever the circuit immediately upon exceeding their amperage rating, a slow-blow fuse is engineered to withstand temporary current surges—often referred to as inrush current—that occur when high-power equipment is first switched on. This feature is essential for welding machines, which often draw a momentary spike of power to energize transformers and capacitors without indicating an actual fault condition.

Using the correct fuse type is paramount for the longevity and safety of your machinery. Installing a fast-acting fuse in a circuit designed for a slow-blow fuse can result in constant, nuisance failures every time the machine is powered up. Conversely, using a fuse with a higher amperage rating than specified can compromise the protection of sensitive internal boards, potentially leading to catastrophic failure of expensive components like control PCBs or fan motors. The ESAB 950358 ensures that your equipment remains protected against sustained overcurrent events and short circuits while allowing for normal operational fluctuations.

As a genuine OEM part, this fuse guarantees compatibility with the specific fuse holders and circuit requirements of your ESAB equipment. It is manufactured to strict quality standards, ensuring consistent performance and reliability. Whether you are performing routine maintenance or troubleshooting a sudden power loss in a specific subsystem of your welder, replacing a blown fuse with the exact manufacturer-specified part is the first step in restoring full functionality. This component is typically found in control circuits, auxiliary power supplies, or fan assemblies within the welding power source.

Industrial environments demand robust components. This fuse is built to handle the rigors of professional use, providing peace of mind that your equipment is safeguarded against electrical anomalies. Always verify the part number in your equipment's service manual before installation to ensure this 1A, 250V slow-blow fuse is the correct specification for your machine.
