Miller Smith Quickbraze Twin-Flame Flexible Tip for Versa-Torch

Master Difficult Joints with the Miller Smith AT400 Twin-Flame Tip

For welders and tradespeople facing the challenges of pipe fabrication and HVAC repair, the Miller Smith AT400 Twin-Flame Tip represents a significant upgrade in brazing technology. This specialized tip is designed to fit the versatile Quickbraze Versa-Torch handle, offering a seamless integration into your existing Smith equipment lineup. The AT400 is specifically tailored for brazing copper tubing with outside diameters between 7/8 inch and 1-5/8 inch, a common range for commercial refrigeration and plumbing applications.

The standout feature of the AT400 is its ability to deliver heat from two sources at once. The twin-flame design effectively "hugs" the pipe, creating a uniform heat zone that drastically reduces the time required to reach the liquidus temperature of brazing alloys. This rapid, even heating is critical for preventing cold joints and ensuring that the silver solder or brazing rod flows smoothly into the fitting cup. By heating from both sides, the operator minimizes the manipulation required, which is a massive advantage when working in awkward positions or on ladders.

Real-world applications often involve tight spaces where rigid torches simply cannot fit. The AT400 solves this with its twin 5-inch flexible tubes. These tubes can be adjusted to reach behind pipes, around corners, or into recessed areas within equipment housings. This adaptability prevents collateral heat damage to surrounding sensitive components and ensures the flame is directed solely at the joint. The unit is shipped with LP2 tip ends, making it ready for use with Propane, Natural Gas, or Propylene immediately. These alternative fuels are often preferred for their availability and safety profile in certain environments.

Investing in the AT400 means investing in speed and quality. The Quickbraze system's "push-to-connect" style ensures that swapping between this twin tip and other attachments is instantaneous. No wrenches are needed, and the connection remains secure and leak-proof. For professionals who value their time and the integrity of their work, the Miller Smith AT400 is the ultimate tool for efficient, high-quality pipe joining.
