DHC2000-2 - DHC2000 #2 Air-Acetylene Heating Tip for Body Leading

Precision Low-Temperature Heating with the DHC2000 #2 Air-Acetylene Tip

The Detroit Torch DHC2000-2 #2 Tip represents a specialized accessory for the DHC2000 oxy-fuel welding system, engineered to convert the standard oxy-acetylene setup into an air-acetylene heating tool. Unlike standard welding tips that rely on a mix of compressed oxygen and fuel gas to achieve high-temperature combustion, this #2 tip utilizes a venturi design to draw in ambient atmospheric air. This mixture with acetylene gas creates a significantly cooler, broader, and softer flame profile, operating within a temperature range of 400°F to 900°F. This thermal range is critical for metallurgical processes that require heating without reaching the melting point of ferrous substrates, such as soft soldering and the application of body lead.

In industrial maintenance and automotive restoration contexts, thermal management is paramount. The DHC2000-2 allows operators to utilize the ergonomic benefits and precision control of the DHC2000 pistol-grip handle while performing tasks traditionally relegated to separate air-fuel torches or plumbing torches. By eliminating the stream of pure oxygen, the risk of oxidation and burn-through on thin-gauge sheet metal is drastically reduced. This makes the tip an indispensable asset for MRO professionals dealing with radiator repairs, electrical soldering on heavy lugs, or the delicate art of body leading where base metal distortion must be minimized.

The tip's construction ensures compatibility with the low-pressure mixing chamber of the DHC2000 system. It is specifically calibrated for acetylene gas, leveraging the high carbon content of the fuel to maintain a stable flame even with atmospheric oxygen levels. This configuration provides a reducing atmosphere that is beneficial when working with fluxes and lead-tin alloys, ensuring proper wetting and adhesion. The #2 size offers a balance between heat output and precision, capable of heating localized areas effectively without spreading excessive thermal energy to surrounding components.
