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.
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.
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.
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.
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.
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.
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.

Construction machinery and special vehicles such as shovel cars, wheel loaders, bulldozers, and
forklifts are utilized in industries all over the world. The welding technology for this equipment
demands high-quality and efficiency. Our company's water-cooled
robotic torches and water-cooled semi-automatic torches are being used in construction machinery
production.

Welding has become an indispensable industry for railway vehicles such as high-speed, subway, non-stop,
and cargo in-use all over the world. Roofing, flooring, and lateral steel plates are welded together
with base frame, pillars and eaves. Our company's
TL series, CSH series, and air-cooled robotic torches are being used in railway vehicle production.
