Master Appliance: Over 65 Years of Heat Tool Innovation

Located in a modern manufacturing facility in Racine, Wisconsin, Master Appliance introduced the first industrial-quality heat gun to the worldwide marketplace in 1958. That milestone set the tone for a brand that has spent more than six decades at the forefront of heat technology — not just following industry standards, but defining them.

With over 60 years of experience, the Master name stands for uncommon expertise in heat technology, quality products, and unsurpassed service. They cater to industrial, aerospace, automotive, electrical, and manufacturing professionals, providing tools designed for durability and efficiency. Whether you're a seasoned technician or a determined DIYer, Master Appliance builds tools that are engineered to keep up.

A Full Lineup of Professional-Grade Heat Tools

Master Appliance's catalog spans the full spectrum of heat-related applications. Their flagship heat guns — sold under iconic sub-brands like Proheat®, Varitemp®, Master-Mite®, and Ecoheat® — remain the cornerstone of the lineup. Their expertise in industrial heat guns ensures you get tools that deliver power, precision, and reliability when it matters most, with professional-grade models engineered to withstand the toughest jobs.

In 1985, Master Appliance made history again. They introduced the first butane-powered soldering iron and heat tools to the North American marketplace. That spirit of innovation lives on in their Ultratorch® line of soldering irons, which serve contractors, electricians, and electronics technicians alike. Whether you need to solder, desolder, install heat shrink tubing, or braze two distinct kinds of metals, Master has you covered.

Portable power is a hallmark of the Master Appliance experience. Their torches range from heavy-duty propane torch heads to compact, precise microtorches. Don't let the small size of a butane torch fool you — these tools are one of the best assets a DIY enthusiast or welder can have, specifically designed to provide high temperatures to small areas, making them ideal when working with jewelry or soldering thin electrical wires.

Keeping those butane tools running is easy with Master's own butane refill fuel. They offer triple-refined butane refills for all multifunctional, portable soldering irons, flameless butane tools, and butane torches, with their Ultratane® butane being the cleanest burning fuel on the market, guaranteeing consistent and uniform heat.

Rounding out the lineup are hot melt glue sticks and cordless glue guns, which bring the same professional-grade build quality to adhesive applications. Four brass hot glue gun tips and three different types of glue sticks are available from Master Appliance, with Portapro Glue Gun accessories perfect for carton closing and woodworking projects.
