MILLER-SMITH EQUIPMENT Cutting Torch

Oxy-fuel cutting is a process that uses flame generated by burning oxygen and fuel gas to cut metal workpieces. Miller-Smith Equipment cutting torches can be used with any fuel gas like acetylene, propane, propylene, natural gas & more for providing a flame hot enough to melt & cut workpieces.

Cutting Torch

Miller-Smith cutting torches are ideal for heating & cutting metal workpieces using oxygen and any fuel gas like acetylene, propane, propylene & natural gas. They have two connections for attaching to gas supply lines from gas cylinders. Miller-Smith cutting torches have 75, 90 & 180 degrees head angles to fit cutting tips for cutting workpieces up to 24 inches at diverse angles from the user. They are equipped with gas knobs for controlling the oxygen to fuel gas ratio of the generated flame and a cutting oxygen lever for supplying high-pressure oxygen to melt & blow away the molten metal. These Miller-Smith cutting torches only need fitting of gas lines / hoses and cutting tips for fully assembling. Users need to hand tighten the cutting tip at the Miller-Smith cutting torch head after wrench tightening them. Miller Smith cutting torches have a sturdy body with an in tip mixture to mix & burn oxygen & fuel gas separately. The cutting tip seat is made of Graf-Tite to maintain positive seating & withstand extremely high temperatures.
Choose from a wide range of these Miller-Smith cutting torches, available in lengths ranging from 36 to 60 inches on Raptor Supplies. We also offer Miller-Smith cutting torch kits having torch handles that can fit cutting attachments, heating nozzles & welding nozzles for performing diverse cutting, welding & heating operations.

Uses

Miller Smith cutting torches are used to cut workpieces made of metal or metal alloys for fabrication, construction, maintenance, demolition, salvaging and shipyard applications.

Working Mechanism

  • After assembling a Miller-Smith cutting torch (fitted with cutting tip) to the hose lines and gas cylinders, start turning the fuel and oxygen cylinder valve.
  • Then, control the fuel & oxygen pressure using the regulator attached to cylinders, according to the material to be cut.
  • Open the fuel & then the oxygen knob on Miller-Smith cutting torch and use a striker or lighter to start a flame.
  • Control the torch fuel & oxygen knobs for adjusting the flame to neutral flame conditions.
  • Now, bring this set-up Miller-Smith cutting torch near the workpiece and start heating near the cutting edge.
  • After a certain time, when the edge starts melting, press the cutting oxygen lever and start cutting the metal workpiece.
  • After cutting the metal piece, close the fuel and the oxygen valves on both Miller-Smith cutting torch & gas cylinders. Sand the cut metal piece for smooth edges. The torch assembly must be purged of any gas mixture left before disassembly.

Features

  • Miller Smith cutting torches are ideal for cutting & gouging metal workpieces using a flame generated by burning oxygen and any fuel gas.
  • They have sturdy construction with slip-in tip design for attaching cutting tips securely.
  • These Miller-Smith cutting torches are compatible with fuel gases like acetylene, propane, natural gas, propylene and hydrogen.
  • They have 75, 90 or 180 degrees angled heads for cutting applications at diverse angles.
  • These Miller-Smith cutting torches are equipped with a cutting oxygen lever for delivering high-pressure oxygen to blow away preheated molten metal & begin the cutting process.

Compatible Accessories

  • Fuel hoses: Two fuel hoses, one carrying oxygen and another carrying fuel gas, are fitted into the connections of Miller-Smith cutting torches.
  • Gas cylinders: Miller-Smith cutting torches require oxygen & fuel gas supply at desired flow rate / pressure from gas cylinders or other sources for efficient cutting operations.
  • Cutting tip: These cutting tips having diverse designs attach to Miller-Smith cutting torch head to provide clean cuts on heated metal surfaces.
  • Fuel regulators: These fuel regulators regulate the pressure & oxygen to fuel gas ratio in Miller-Smith cutting torches for optimum cutting performance.
  • Flashback arrestor set & reverse flow check valves: These flashback arrestor sets & reverse flow check valves prevent fire related accidents / hazards due to reverse flow of flame or fuel gases from the torch tip into the gas line of Miller-Smith cutting torches.
  • Welding helmets: Users or operators need to wear welding helmets to protect themselves from sparks or metal pieces generated during the cutting operation.
  • Striker or lighter: These strikers or lighters are used to ignite the oxygen-fuel gas mixture in front of Miller-Smith cutting torch's cutting tip to start the flame. Users should use a striker that can be fired from a distance to protect their hands from injuries.

Standards and Approvals

  • Miller-Smith cutting torches are manufactured by Miller Electric Mfg. Co. in accordance with ISO 9001:2015 standard certified company for user safety and superior cutting performance. Operators should follow OSHA guidelines for a safe, accident-free operation.

Installation

Miller-Smith cutting torches feature connections for directly fitting two hoses (oxygen and fuel gas) attached to their respective gas cylinders. Miller-Smith cutting torch head should also be fitted with an appropriately sized cutting tip for achieving desired cut on the metal workpieces.

Frequently Asked Questions

What size fuel gas tank should users select to efficiently run the cutting operation?

Size of a gas tank for use by Miller-Smith cutting torches is determined by the fuel gas used and its consumption along with oxygen gas. Generally, acetylene cylinder capacity per hour is seven times that of tip requirement. Alternate fuel (LP) gas cylinder capacity depends on the temperature but normally have greater gas volumes than acetylene cylinders.

Can natural gas delivered through utility pipes be used by Miller-Smith cutting torches?

Yes, natural gas delivered through utility pipes can be used by Miller-Smith cutting torches. However, this fuel gas supply is generally not pressurised enough to efficiently cut workpieces. Users may need a separate fuel gas manifold line to force the gas at enough pressure to reach the tip & generate a flame at a distance away from Miller-Smith cutting torch tips.

How to select the right fuel gas type for use in Miller Smith cutting torches?

Selecting a fuel gas for Miller-Smith cutting torches depends on several parameters like application requirements, workpiece thickness, material properties and the cost / availability of the fuel gas. Users should test each fuel gas over a set period to compare the work efficiency and overall cost of the gases used. Miller-Smith cutting torches generally are compatible with all fuel gases and only require compatible cutting tips for operation.

How to avoid overheating of Miller-Smith cutting torches?

Two main reasons for a Miller-Smith cutting torch & its tip to overheat are incorrect flame adjustments and insufficient gas supply to the torch. Generated flame lacks the velocity required to burn away from the cutting tip if enough gas is not supplied to Miller-Smith cutting torch. The resulting flame may recede into the torch & cause overheating. Users should use high-flow flashback arrestors with large cutting tips for less gas flow resistance & reduced overheating. They should also provide an appropriate amount of oxygen to prevent overheating as oxygen has a cooling effect on Miller-Smith cutting torch & its cutting tip.

What grade of the hose is suitable for use with Miller-Smith cutting torches?

Users should use "R" grade hoses with Miller-Smith cutting torches when the fuel gas used is acetylene and "T" grade hoses when they are using alternate fuel (LP) gases, such as propane, propylene and natural gas.
