  • SOLDERING KIT CONTENTS: Our PI-40SiK kit has a professional butane soldering iron, two (2) pre-tinned solder tips, a hot knife tip, a heat shrink reflector, lead-free solder, a sponge/tray, and a protective cap. All of these are placed in a hard-shell case. You get all the soldering tools you need in one pack.
  • CORDLESS AND PORTABLE: Using butane fuel, you can solder conveniently without dealing with tangled wires. You can perform soldering or welding work freely because our butane-powered soldering is lightweight. Weight: 3.3oz (.21 lbs; 93 grams) without fuel.
  • ADJUSTABLE SOLDERING TEMP: Easily control the cordless soldering iron's temperature from 635F to 900F (335C to 482C) and solder different temperature applications. The feature makes it easier to deal with heat-sensitive or temp-specific components. Our soldering iron also has an adjustable open flame function (butane torch).
  • LONGER RUN TIME: PI-40SiK portable soldering iron has a refillable tank capacity of approximately 0.31oz/8.25g. One butane refill will last up to 75 minutes of run time. For better performance, fuel the soldering irons with our Master Ultratane butane fuel.

Description

Master's PI-40SiK butane-powered soldering iron is a 3-in-1 tool that also functions as a flameless heat tool and pinpoint torch. This portable soldering iron kit comes with 4 different attachments: 2 pre-tinned soldering tips, a heat shrink reflector and a hot knife tip. User-friendly and versatile, this professional cordless soldering iron kit is an excellent addition to a workshop or toolbox. Great for use on electric wire connectors, a wide array of soldering needs and slicing through rope, welding components and more. Master Appliance is a multi-generational family-owned and operated company for 60+ years located in a modern manufacturing facility in Racine, Wisconsin, USA. We take pride in being the heat tool experts and providing our customers with professionally-engineered products. With six decades of experience, we don't just make heat tools, we make heat tools BETTER. Cordless yet powerful. This soldering iron is butane powered, refillable and can last up to 75 minutes on a full tank. Corded soldering irons can be restricting and bothersome, take this soldering iron on the go to work on your projects. Our butane torch and soldering iron kit comes with two pre-tinned solder tips. Tinning helps in the prevention of oxidation and rusting. Tinned tips are also helpful in melting the soldering wire and making it flow more easily over the components being worked on. We included components and accessories in this soldering iron, flameless heat tool, and torch kit that can help users complete projects more efficiently. It has a hot knife tip that can cut and remove stray or extra materials, reach slotted cavities, fix solder bridges, etc. With the heat shrink reflector attachment, this butane heat tool is useful in heat shrink tubing applications. It catches the hot air that could blow past or around a heat shrink and then reflect the hot air to the tube's opposite side. We introduced our industrial quality "Master Heat Gun" to the worldwide marketplace in 1958. We take pride in being THE heat tool experts with professionally engineered heat tools designed to perform in some of the most demanding work environments worldwide. With six decades of experience, we don't just make heat tools. We make heat tools BETTER. In 1985, we introduced high-quality butane-powered soldering iron/heat tools to the North American marketplace. Today our heat tools are used for drying, heating, welding, shrinking, soldering, and many other applications where heat is needed.

High quality
This my second Iron, My old one lasted 20 years before the adjustment lever stopped working. This new one works great. I like the high quality construction and function. Too bad it cost more to get the old one repaired than getting a new one.
