Features

  • Harris cutting torches have brazed triangular tube design and connections for strength and durability under harsh usage in extreme environments.
  • They have either "F" injector / low-pressure mixing system or "E" equal / positive pressure mixing system for producing flames having diverse temperatures at various fuel gas / oxygen pressures.
  • They are equipped with gas knobs for controlling the flame by changing the oxygen to fuel gas ratio and a flip-up cutting oxygen lever made of forged brass for ease-on oxygen supply, smoother starts & precise cutting control.
  • These cutting torches are further equipped with FlashGuard check valves for stopping the reverse flow of flammable oxygen & fuel gases into the hoses and causing fire-related accidents.
  • Harris cutting torches have a solid forged brass head with a 90-degree head angle for placing the cutting tip perpendicular to workpieces and resisting abuse or distortion.

Working Mechanism

  • Two inlet connections of Harris cutting torches are fitted with two hoses (oxygen and fuel gas) that are attached to their respective gas cylinders through a fuel / pressure regulator.
  • The cutting torch head is also attached with a cutting tip according to desired size & depth of the metal workpieces to be cut.
  • Start turning the fuel and oxygen valve on the gas cylinders and set the fuel & oxygen pressure using attached regulators according to the material to be cut.
  • Open the fuel & oxygen knob on the Harris cutting torch and light a flame using a striker or lighter. Adjust the flame to neutral flame conditions.
  • Bring this set-up cutting torch over the workpiece and start heating the cutting edge. Once the edge starts melting, press the cutting oxygen lever to start cutting the metal workpiece.
  • After the metal piece has been cut, the fuel and the oxygen valves on both the cutting torch & gas cylinders should be closed. The cut metal piece should be sanded for smooth edges. Purge the torch assembly of any gas mixture left before disassembly.

Standards and Approvals

  • UL listed
  • OSHA

Frequently Asked Questions

How hot is the flame generated by Harris cutting torch?

Harris cutting torches generate a preheat flame by mixing oxygen and fuel gas in diverse ratios. The flame's temperatures may range from 4400 to 6000 degrees F.

What is the main difference between a cutting torch and a welding torch?

The main difference between a cutting torch and a welding torch is their primary function. Cutting torches are used to cut metals into smaller pieces, whereas welding torches are ideal for joining different metal pieces together. These torches can not be used interchangeably, so users should use the appropriate torches for their applications.

What are the points to remember before operating Harris cutting torch?

  • The cutting torch tip should be checked for clogged debris or cut metal particles.
  • Selected cutting torch should be free from any cracks or breaks to prevent fuel or oxygen leaks.
  • Users should make sure that the valves, knobs, hoses & pressure gauges deliver desired pressure from tanks into the torch lines.

How to avoid overheating of Harris cutting torches?

Primary reasons for a cutting torch to overheat are insufficient gas supply and incorrect flame adjustments. If insufficient gas is supplied to a cutting torch, the generated flame may not burn away from the cutting tip and recede back into the torch to cause overheating. Users should supply an appropriate amount of oxygen to prevent overheating as oxygen has a cooling effect on the cutting torch & its cutting tip. They may also use high-flow flashback arrestors with large cutting tips for less gas flow resistance.

How to choose the right fuel gas for use in Harris cutting torches?

Users should choose the right fuel gas for cutting torches based on parameters like application requirements, material properties, workpiece thickness and fuel gas cost / availability. Each fuel gas should be tested over a set period to compare its cutting efficiency and overall cost.
