Microtorch for precision heating

The Master Appliance MT-51 is a butane-powered microtorch designed for detailed thermal work. It suits technicians and hobbyists who need a portable flame for soldering, heat-shrink tubing or terminating specialty connectors. The self-igniting mechanism with a safety lock allows one-handed operation. It is not suited for heavy fabrication or high-volume welding tasks.

2500 °F adjustable flame with two-hour runtime

The torch reaches a flame temperature of 2500 °F and offers an adjustable output ranging from a broad flame to a pinpoint tip. A full charge of the built-in refillable tank provides up to two hours of continuous burning. The unit meets CSA, CPSC and TUV/GS safety standards. Noise and vibration are minimal during normal use.

Refillable tank and hands-free lock for bench work

The integrated plastic fuel tank eliminates the need for disposable cartridges and can be refilled from standard butane cans. A hands-free lock holds the flame steady when the tool is set down, freeing both hands for positioning workpieces. No external hose or regulator is required. Ensure adequate ventilation when operating indoors.

Questions about this item

How do I refill the built-in butane tank and what is the step users often miss?

Hold the torch upside down, press the butane canister nozzle firmly into the refill valve until you hear a hiss, wait a few seconds, then engage the safety lock before igniting; the step often missed is waiting for the fuel to stabilise after filling.

What part will need replacement after extended use and how often?

The self-igniting piezo spark mechanism is the wear item; with regular use it typically requires replacement after several hundred ignition cycles.

At what point does the flame temperature drop during continuous operation?

The 2,500 °F flame holds steady for the full two-hour burn time on a full charge; temperature only falls when the butane level becomes too low to sustain pressure.
