What It Is

The Master Appliance MT-51B is a self-igniting butane microtorch with a built-in refillable tank and a 120-minute run time. It reaches a maximum torch temperature of 2,500 degrees Fahrenheit and includes a 15/16 oz can of butane. The tool functions as both a pinpoint torch and a flameless heat tool.

Who It Suits

Technicians performing desoldering, shrink tubing, soldering or specialty connector termination will benefit from the adjustable flame that ranges from broad to pinpoint. The hands-free lock supports extended bench work. Buyers needing a tip included in the package or a longer continuous run time should look at other models.

Build Integration

The refillable tank and included butane canister let the torch operate without an external fuel line or electrical outlet. Its self-igniting mechanism removes the need for a separate striker. The compact hand-held or table-top form factor fits on a crowded workbench and frees up space otherwise taken by a soldering station power supply.

Questions about this item

Does the MT-51B come with a tip so I can start soldering immediately?

The Microtorch ships without a tip; you must supply a compatible tip for the pinpoint torch or flameless heat functions.

Can I use the self-igniting MT-51B alongside my older manual striker torch without changing fuel?

Both torches run on butane, so the MT-51B’s built-in refillable tank works with the same canisters you already use.

How do I confirm the MT-51B reaches its 2,500 °F maximum temperature after refilling?

Adjust the flame to pinpoint; a steady, intense blue cone indicates the torch is delivering full rated heat.
