Harris heating torches are heavy-duty industrial oxy-fuel systems widely recognized for high BTU heat output, safety, and efficient gas mixing. Manufactured under The Lincoln Electric Company, Harris equipment utilizes specialized injector and equal-pressure technology to serve applications like preheating structural steel, stress-relieving welds, flame straightening, and heavy brazing across Oxy-Acetylene and Oxy-Propane/LPG gas setups.
Key Technical Features & Capabilities
• Low-Pressure Injector Technology: Harris K-43 and Model 63-2 heating torches feature low-pressure suction injectors (Universal Pressure / Model 43-2), allowing efficient operation on alternative fuel gases like Propane, LPG, Natural Gas, and Mapp at fuel gas pressures as low as .
• High BTU Output Heating Tips: Compatible with Harris 2290 series heating tips (such as 2290-H for Acetylene or 2290-HPM for Propane/LPG), engineered to deliver up to for rapid temperature elevation on thick steel sections.
• Equal-Pressure & Alternate Fuel Designs: Offers dedicated equal-pressure mixers for high-flow Oxy-Acetylene heating alongside specialized multi-flame tip extensions (e.g., F-43 and TH-119 heating necks) that optimize flame stability and prevent blow-offs.
• Heavy-Duty Construction: Built with silver-brazed stainless steel tubes, high-flow forged brass shank handles, and dual O-ring seal mixers for gas-tight sealing and thermal endurance under continuous operation.
• Flashback Prevention: Integrated with non-shear internal components and designed to pair with high-flow flashback arrestors to ensure maximum safety during high-demand heating cycles.
Primary Industrial Applications
1. Preheating Steel Plates: Essential for raising temperature prior to heavy welding to prevent cold cracking in structural steel.
2. Flame Straightening & Bending: Applied in shipyards and heavy fabrication to correct distortion in I-beams and heavy plates.
3. Expansion Fitting: Facilitates shrink-fitting of large industrial gears, bearings, and mechanical shafts onto assemblies.
