Injection Cutting Welding Torch Professional GASPRO Welding & Cutting Torch Kit for Distributors
This welding tool that combines welding, cutting, and heating by mixing combustible gases (such as acetylene and propane) with oxygen and igniting them at the nozzle to produce a high-temperature flame (up to 3100 ° C or above).
The main usage functions：
1. Welding
Gas welding: mainly used for welding thin black metals (such as low-carbon steel plates), copper alloys, cast iron repairs, etc. Form a weld seam by melting the base material and welding wire.
Brazing/Silver Welding: Heating the base material to melt and fill the joint with lower melting point brazing materials (such as copper welding rods, silver welding rods), connecting metal parts (commonly used in pipelines, radiators, jewelry, etc.).
2. Cutting
Flame cutting: Replace with a dedicated cutting nozzle (one of the nozzles in the set may be used for this function), use a high-temperature flame to locally preheat the metal to the ignition point, and then spray a high-speed oxygen stream to vigorously oxidize (burn) the metal and blow it away, thereby cutting the metal (mainly used for carbon steel).
3. Heating and thermoforming
Preheating: Preheat before welding thick plates or cast iron to prevent cracking.
Annealing: Local heating and gradual cooling of metals to reduce hardness and relieve stress.
Bending: Heating the metal locally to a red hot state, making it easier to bend or shape.
4. Other hot processing
Smelting a small amount of metal, hot dismantling rusted bolts, drying, etc.
Operating parameters:
Applicable gases: flammable gases such as propane and acetylene are used in combination with oxygen.
Working pressure: Gas pressure typically ranges from 0.01-0.1 MPa; Oxygen pressure: 0.1-0.8 MPa (please refer to the product manual for details).
Flame temperature: up to approximately 3100 ° C (when using acetylene).
FAQ：
1.Q: What types of gas can this torch use?
A: This torch is designed to work with common fuel gases such as Propane (LPG), Acetylene, or MAPP gas, combined with Oxygen. Always check the manual to confirm compatibility with your specific gas type.
2.Q: What are the recommended working pressures for fuel gas and oxygen?
A: Typical working pressure ranges are 0.05–0.15 MPa (5–15 psi) for fuel gas and 0.2–0.8 MPa (30–120 psi) for oxygen, but exact values depend on the nozzle size and task. Refer to the manual for precise settings.
3.Q: How do I switch between welding, heating, and cutting modes?
A: Switch modes by changing the nozzle/tip and adjusting the gas mix. Use a smaller tip for welding, a larger one for heating, and a dedicated cutting attachment (if available) for cutting.
4.Q: Is this torch suitable for beginners or DIY users?
A: Yes, but with caution. Proper training on gas handling, flame adjustment, and safety procedures is essential. Always practice in a safe, ventilated area with protective gear.
5.Q: How do I prevent flashback (fire shooting back into the torch)?
A: Always use flashback arrestors on both fuel and oxygen lines, maintain correct gas pressures, and light the torch in the proper sequence (fuel first, then add oxygen).
6.Q: Can I use this torch for soldering or brazing?
A: Absolutely. With the right nozzle and a neutral/oxidizing flame, this torch is ideal for brazing copper, silver soldering, and general metal joining.
7.Q: What maintenance does the torch require?
A: Regularly check for leaks, clean nozzles to prevent clogs, inspect hoses and fittings, and store in a dry place. Replace worn parts immediately.
8.Q: What safety gear do I need when using this torch?
A: Essential gear includes safety goggles/face shield, heat-resistant gloves, flame-retardant clothing, and proper footwear. Work in a well-ventilated area away from flammables.
9.Q: Why is my flame unstable or yellow?
A: This usually indicates incorrect gas pressure, a clogged nozzle, or an improper gas mix. Check pressures, clean the tip, and adjust for a neutral flame (blue with a sharp inner cone).
10.Q: Can I order custom branding or packaging for bulk purchases?
A: Yes, we offer OEM/ODM services including custom branding, packaging, and nozzle configurations for bulk orders. Contact our sales team for details.
