Master Appliance Ultratorch UT-100SI Butane Kit

The Master Appliance Ultratorch UT-100SI is a cordless butane-powered soldering kit built for field service and on-site repairs. It ships with five interchangeable tips covering chisel, heat shrink, hot air, knife and needle profiles. The self-igniting mechanism removes the need for a separate lighter. Maximum torch temperature reaches 2,500 Degrees F for broad heating tasks.

Suited for mobile technicians needing flameless heat

This kit suits mobile technicians who need a portable flameless heat tool for soldering, heat-shrink tubing or light cutting without mains power. The 120-minute run time supports extended jobs away from a bench. Buyers who require continuous high-wattage output for heavy joints or who need temperature readouts should look at something else.

80 W equivalence with 120-minute run time

Electric iron power equivalence spans 20 W to 80 W, giving headroom for delicate 0.5 mm needle work up to wider 8 mm chisel tasks. Maximum solder tip temperature is 932 Degrees F while the hot air tip peaks at 1,202 Degrees F. The butane tank delivers roughly 120 minutes of operation before refill, limiting non-stop use on long production runs.

Questions about this item

What butane fuel do I need to run the Ultratorch UT-100SI?

The kit requires standard butane refill canisters, which are sold separately. One fill provides up to 120 minutes of continuous operation.

Can I use the hot-air tip on heat-shrink tubing rated for lower temperatures?

Yes. The hot-air tip reaches a maximum of 1,202 °F, while the solder tips run up to 932 °F. Adjust the flame control toward the 20 W equivalent setting for gentler heat.

How do I confirm the self-igniting piezo is working after I fill the tank?

Open the gas valve, press the ignition button and look for an immediate flame at the torch tip. A steady blue flame means the piezo and fuel flow are both functioning correctly.
