1300380 - Harris 72-3 Medium Duty 90-Degree Cutting Attachment

Harris Model 72-3 Medium Duty Cutting Attachment

The Harris Model 72-3 Medium Duty Cutting Attachment (SKU: 1300380) represents a pinnacle of engineering in the field of oxy-fuel cutting equipment. Designed for professionals who demand reliability and precision, this attachment is built to withstand the rigors of daily industrial use while maintaining exceptional performance. The unit features a classic 90-degree head angle, making it suitable for a wide variety of cutting positions and applications, from structural steel fabrication to general maintenance and repair.

At the core of the Model 72-3 is Harris's signature triangular stainless steel tube design. This innovative construction method provides a superior strength-to-weight ratio compared to traditional parallel tube designs. The triangular configuration ensures exceptional rigidity, preventing the tubes from bending or warping under stress, while keeping the overall weight of the attachment low to reduce operator fatigue. The connections are brazed to ensure leak-free performance, providing peace of mind in hazardous environments.

Safety and longevity are paramount in the design of the 72-3. The attachment utilizes a solid forged brass head that resists abuse and heat distortion, ensuring that the seating surfaces remain true over years of service. A captive union nut is employed to protect the precision-machined seats and O-rings from damage during the connection process to the torch handle. Furthermore, the unit is equipped with an equal or positive pressure mixing system (E-mixer), which significantly reduces the risk of flashback and damage to the equipment.

Operational control is enhanced by the inclusion of an "ease-on" cutting valve. This feature allows for a gradual introduction of cutting oxygen, resulting in smoother, more controlled starts and cleaner cuts. The cutting lever is designed to fold forward, facilitating easier connection to the torch handle and providing convenient operation even when the user is wearing thick protective welding gloves. Compatible with all fuel gases, this attachment offers the versatility needed for modern workshops.
