0821441884 - ESAB PEK Crosshair Laser Alignment Kit

Precision Optical Alignment for Automated Cutting

The ESAB Laser Lamp Kit PEK/Crosshair (Part Number 0821441884) is a specialized component engineered for the rigorous demands of automated industrial cutting systems. In high-precision CNC environments—spanning plasma, oxy-fuel, and laser cutting applications—the ability to accurately establish a program zero point is fundamental to process efficiency. This laser module projects a sharp, defined crosshair pattern onto the workpiece surface, providing operators with an immediate visual reference for the torch's position relative to the plate edge or internal features. It is designed to interface seamlessly with ESAB's PEK process controllers and associated carriage assemblies.

Manufactured to withstand the harsh conditions typical of fabrication facilities, the module features a sealed housing that resists the ingress of conductive dust, metallic particulate, and cutting fumes. The optical components are shock-mounted to endure the constant acceleration and deceleration forces of gantry movement without losing calibration. When an alignment laser fails, the operational impact is immediate: setup times increase as operators revert to manual measurement methods, and the risk of torch collisions or off-center cuts rises significantly. This kit restores full functionality, ensuring the machine's coordinate system aligns perfectly with the physical material.

Installation of the 0821441884 kit is straightforward, utilizing the existing mounting points and power connections on the machine carriage. As an OEM part, it guarantees correct voltage matching and signal integration, eliminating the flickering or premature failure often seen with generic aftermarket laser pointers. It is an essential spare part for maintenance teams supporting ESAB Suprarex, Alpharex, or similar gantry systems equipped with PEK controls.

By maintaining a clear and bright visual indicator, facilities can ensure optimal material utilization through tighter nesting and reduced edge margins. This kit includes the necessary cabling and hardware to effect a complete repair, returning the cutting system to its full operational capability with minimal downtime.
