Our Business
Tokin, as an arc welding torch manufacturer, is uncompromising with made in japan quality. The welding of metals is essential for many industries and our welding torches and robot peripherals are sold not only in Japan but around the world.

The TokinArc® trademark is sold domestically in Japan through nearly 200 distributors and internationally starting with North America, Europe, India, China, SE Asia, Oceania, South America, South Africa, and expanding to other regions around the world. Our products are used in automobile production, electrical equipment, steelmaking, and shipbuilding among other fields.

Welding, which supports all industries including automotive, steelmaking, shipbuilding, aircraft manufacturing, atomic energy, and space exploration, undergoes changes in needs depending on environmental and technical requirements. Therefore, Tokin delivers the appropriate depth and breadth of products with variation and customization necessary to meet our end user's unique objectives and welding conditions.
Overview of Welding
Welding, depending on the joining method, is classified into the following three categories. “Fusion” when a base metal is heated and melted with or without a filler metal to then solidify and create a bond, "Pressing" when mechanical pressure is used to create a bond, and "Brazing" when a bond is created only by melting a filler metal but not the base metal. Tokin focuses on a method of fusion known as “Arc Welding”, specializing in arc welding torches and related equipment.
Robotic Welding
Today with automation advancing in many fields the use of computer-controlled robotic manufacturing systems are increasing. At Tokin the demand for “robotic torches” and “robot peripheral equipment” is growing.
The standard composition of an industrial arc welding robot system is illustrated in the above drawing. Depending on the welding method a power source, welding torch, wire feeder, and other devices are adjusted to meet the welding requirements and utilized. Tokin, as a torch specialist, manufactures torches which mount to the end of the robot arm and are durable enough to run in automatic welding operations. We supply power cables and flexible conduits compatible with all types of wire feeders.
Semi-Automatic Welding
Semi-Automatic Welding
In semi-automatic welding several kilowatts of power are supplied by the power source and travel through not just the torch but the wire, wire feeder, and wire spool. In addition to electricity, through the torch hose shielding gas is supplied from a gas tank to the welding point. The power source precisely controls the wire speed. Our company manufactures semi-automatic torches, wire drum dome covers, and quick connection adapters.
Our products are the preferred model in various manufacturing production lines.
Automobile Manufacturing
Starting with the automobile industry and continuing into transport aircraft, welding materials and methods appropriately suited for varying types of steel such as galvanized and stainless are being utilized. If you look at the accompanying figure can see that welding is used for every part. Our company's TL series, air-cooled robotic torches, and TIG welding torches are being used in automobile production.

Shipbuilding
In the production of a large steel ship in Japan, the welding of the bilge using semi-automatic torches is commonplace. However, as in the below figure a system called the "hull block construction method (HBCM)" is also widely used. In addition, since this process utilizes large machine tools in indoor block assembly plants, computer-controlled gas plasma torches and similar devices are further realizing efficiency and accuracy. Robotic welding systems are utilized in large sections called panel lines, where in particular efficiency is advancing. Our company's TL series, CSH series, and air-cooled robotic torches are being used in shipbuilding.

Construction Industry
In the construction of high-rise buildings or similar steel frame structures, shapes such as "H", "rectangular pipe", "round steel", and "L" are welded in large quantities. The welding technolgy for steel frame structures demands high-quality and efficiency, including earthquake-proofing. Our company's TL series, CSH series, and air-cooled robotic torches are being used in steel frame construction.
