Portable Butane Microtorch

The Master Appliance MT-51H is a self-igniting butane microtorch designed for precision heating tasks. It serves technicians and hobbyists who need a cordless flame tool for soldering, heat-shrinking, or general repairs. The integrated refillable tank provides up to 120 minutes of continuous run time per fill.

Check Butane Supply And Tip Needs

Verify you have standard butane fuel canisters available for refilling the built-in tank before starting work. Confirm the included heat-shrink attachment (part 35387) and hot-air tip (part 35394) match the specific diameter and profile required for your current project. Ensure the workspace is ventilated for open-flame or hot-air operation.

Cordless Heat For Bench And Field

The microtorch operates without cords or external power, freeving bench space and allowing use in remote locations. A hands-free lock enables stable, continuous heating when both hands are needed for the workpiece. Broad-to-pinpoint flame adjustment and a maximum torch temperature of 2500 Degrees F cover a wide range of thermal applications.

Questions about this item

Does the MT-51H come with a heat-shrink attachment and hot-air tip, or do I need to buy them separately?

The kit includes both the heat-shrink attachment (part 35387) and the hot-air tip (part 35394) inside the box, so nothing extra is required for those functions.

Should I choose the 2,500 °F torch mode or the 932 °F hot-air mode for my job?

Use the 2,500 °F pinpoint flame for soldering, brazing or metalwork; switch to the 932 °F hot-air tip for heat-shrink tubing, paint stripping or drying tasks.

How long will a full butane tank run the torch at its 2,500 °F maximum?

The built-in refillable tank delivers about 120 minutes of continuous operation at the highest flame setting before it needs refilling.
