0193586103 - ESAB LAF 800 Replacement Automatic Fuse 15A

Reliable Circuit Protection for ESAB Power Sources

The ESAB Automatic Fuse 15A (Part Number 0193586103) is a critical replacement component designed exclusively for the LAF 800 welding power source. As a genuine OEM part, it ensures that your heavy-duty submerged arc welding equipment operates within safe electrical parameters, protecting sensitive internal electronics from overcurrent events and short circuits.

In industrial welding environments, power fluctuations and component faults can occur. This 15-amp automatic fuse acts as a safeguard, interrupting the circuit when the current exceeds safe limits. Unlike standard disposable fuses, automatic fuses (often functioning as circuit breakers) can typically be reset or are designed for specific trip curves that match the machine's operational needs. Using the correct amperage and fuse type is vital for maintaining the manufacturer's safety standards and warranty compliance.

Technical Compatibility

This component is engineered to fit the control panel or internal power distribution assembly of the LAF 800. The LAF series are three-phase, fan-cooled DC welding power sources designed for high-productivity automated submerged arc welding (SAW) or MIG/MAG welding. The 15A fuse likely protects auxiliary circuits, fan motors, or control boards essential for the machine's regulation.

Why Choose Genuine ESAB Parts?

• Precise Fit: Guaranteed to fit the fuse holder or mounting point in the LAF 800 without modification.


• Correct Rating: Calibrated specifically for the 15A load requirements of the designated circuit.


• Durability: Built to withstand the vibration and thermal cycling common in industrial welding setups.

Maintain the integrity of your automated welding line by replacing faulty circuit protection with the original ESAB 0193586103 Automatic Fuse.
