Cordless Butane Soldering Kit

The LEXIVON LX-770 is a cordless butane soldering kit designed for professionals and DIY users who need portable heat for soldering, cutting, and sealing tasks. It operates without a power outlet, using standard butane gas to deliver up to 125-watt equivalent performance. The kit includes 13 specialized parts and a durable aluminum fuel tank that is pre-tested for leaks. A carrying case keeps all components organized for transport and storage.

Field Repairs and Off-Grid Work

This kit suits technicians, hobbyists, and tradespeople who require a self-igniting torch with adjustable flame control for on-site repairs, automotive work, or electronics projects where mains power is unavailable. The flame locks for continuous hands-free operation. Buyers who need temperature-regulated soldering stations with digital readouts or consistent idle heat for long bench sessions should consider mains-powered alternatives instead.

Heat Capacity and Run Time

The torch reaches a maximum temperature of 2400°F (1316°C) at the flame and up to 1100°F when using the soldering tips, providing enough heat for heavy-gauge wire, heat-shrink tubing, and light brazing. The large tank delivers up to 75 minutes of continuous run time and refills in roughly 10 seconds. Extended jobs requiring hours of uninterrupted flame will need spare butane canisters on hand.

Questions about this item

What fuel must I supply for the LX-770 butane soldering kit to operate?

The kit requires standard butane gas, which is not included, and the aluminum tank refills in about 10 seconds for up to 75 minutes of run time.

Can the 13-piece tip set on the LX-770 handle the same tasks as my old electric iron?

The adjustable flame reaches 2400 °F and soldering tips operate up to 1100 °F, covering soldering, cutting, and sealing jobs that a typical electric iron performs.

How do I verify the LX-770 is working correctly after refilling and igniting?

The self-igniting trigger should produce a stable flame adjustable from 1/2 to 2 1/2 inches, and the flame-lock button holds the setting without further trigger pressure.
