Injection-Type Cutting Torch | Full Brass | Oxy-Acetylene Cutting
Model: Injection-Type Cutting Torch | Full Brass Construction | For Steel Cutting & Maintenance
Product Overview
This injection-type cutting torch is constructed from full brass with double metal tubes, designed for reliable oxy-acetylene steel cutting. The injection-type design creates a stable suction effect, making it fully compatible with low-pressure acetylene — ideal for repair shops, construction sites, and small steel-structure processing.
Equipped with three adjusting handwheels for preheat oxygen, fuel gas, and cutting oxygen, the torch delivers precise flame control and smooth cutting performance at a cost-effective price.
Key Advantages
Solid All-Brass Build
Full brass construction provides excellent heat dissipation and corrosion resistance, ensuring long service life even under continuous heavy use.
Stable Suction Performance
The injection-type design generates reliable suction, working efficiently with low-pressure acetylene. No need for high-pressure fuel gas supply — safer and more economical.
Precise Flame Adjustment
Three independent handwheels control preheat oxygen, fuel gas, and cutting oxygen separately, allowing accurate and convenient flame setting for different cutting tasks.
Good Sealing & Anti-Flashback
Precision-machined valves and connections ensure good sealing performance, reducing the risk of flashback and gas leakage during operation.
Cost-Effective & Reliable
Ideal for cutting common-thickness steel with dependable performance at an affordable price point.

Usage Notes
Gas Connection: Connect oxygen and acetylene hoses to the dual hose connectors at the gas-inlet end. Ensure all connections are tight and leak-free before ignition.
Flame Adjustment: Use the three handwheels to adjust preheat oxygen, fuel gas, and cutting oxygen independently. Set a neutral or slightly oxidizing flame for cutting, depending on material thickness.
Nozzle Selection: Fits standard cutting nozzles. Select the appropriate nozzle size based on steel thickness for optimal cutting efficiency.
Safety Precautions:
Always check for gas leaks before use.
Keep hoses away from hot surfaces and sparks.
Use anti-flashback arrestors on both oxygen and acetylene lines for added safety.
Never use oil or grease on oxygen fittings.
Maintenance: Clean nozzles regularly to remove slag and spatter. Store in a dry environment to prevent corrosion of brass components.
FAQ
Q: What type of gas does this torch use?
A: It is designed for use with oxygen and acetylene. The injection-type design works particularly well with low-pressure acetylene.
Q: What is the advantage of the injection-type design?
A: The injection-type principle creates a suction effect that draws low-pressure fuel gas into the torch, making it compatible with low-pressure acetylene sources without requiring high-pressure gas supply.
Q: What nozzles are compatible?
A: The torch fits standard cutting nozzles with an angled mounting position. Select the nozzle size according to the steel thickness you are cutting.
Q: Is it suitable for continuous industrial use?
A: It is ideal for repair shops, construction sites, and small steel-structure processing. For heavy continuous industrial cutting, consider a heavy-duty model.
Q: What safety features does it have?
A: The torch features good sealing performance and anti-flashback characteristics. For maximum safety, always use external flashback arrestors on both gas lines.
