Weld Guns:

 

Servo Guns

Obara started making servo weld guns in the late 1990’s.  With superior performance to pneumatic technology, servo guns quickly became the standard in the automotive industry.  We have worked over the years with our customers to develop equipment with superior design, which is modular, lightweight, and easy to maintain with high durability.  Our latest design is our X2C series, which includes standard, high performance, and aluminum welding.

 

Portable Trans Gun

Also known as the IT gun, (Integrated Transformer) gun, Obara’s portable transformer gun helps reduce electricity consumption and increases welding efficiency.  IT guns from Obara have been installed around the world in our customers’ facilities with a standardized and perfected modular design to maximize user ergonomics.  Its friendly protective cover allows for reduced maintenance times (MTTR).  Custom designs are also available.

 

 

Fixture Guns

Our fixture, or hard tool, gun incorporates a slim and compact design due to the use of superior materials and Obara’s sophisticated machining experience.  A wide variety of welding applications can be solved by selecting the standard gun designs in our catalog.

Portable Spot Welders

Although new technology is constantly being introduced to the market, portable spot welders are still in wide use due to their unparalleled advantages.  We supply portable weld guns worldwide with excellent ergonomics, low cost, and high durability.

Weld Controllers:

Inverter Welding Controller

The inverter Welding Controller allows lower current, lower electrode force and shorter welding cycles in comparison with an AC system.  It also allows a wide range of current to be used at a given electrode force.  By utilizing the inverter system, the wight of the transformer can be reduced by up to 50%.

 

 

AC Weld Controller

Our Welding Controllers are user friendly and have various operations available such as spatter regulation and variable pressurizing.

 

 

Trantim

Obara’s Trantim unit combines a weld controller and a transformer into one convenient package.  The Trantim unit helps to simplify a portable spot welding line by minimizing floor space and wiring without any compromises to weld capacity.

Electrodes and Adapters:

 

 

Electrode and adapter life is very important in resistance welding.  It is affected by many factors; material, manufacturing processes, part geometry, welding conditions, and welding methods.  Obara has been manufacturing electrodes and adapters since its establishment and devoting our efforts to improving their life.  To meet the delivery requirements of our customers, Obara has invested heavily in cold header equipment.

Cables and Shunts :

 

Kickless Cables

“Obara-6X” Kickless Cables are characterized by low impedance and high electrical power factor.  These cables have been developed based on the following parameters.
  • High heat endurance
  • Maximum flexibility and durability
  • optimal water cooling
  • Ease of maintenance

 

 

Water Cooled Cables

Advanced technologies of wire standing, terminal geometry, and crimping method result in exceptional resistance to wear, heat, and oil.

 

 

Air-Cooled Cables

Obara’s air-cooled cables are designed specifically for the harsh conditions of the resistance spot welding environment.  Protective sleeves in several types of materials are available.

 

 

Laminate Shunts

Obara’s laminate shunts are made from high conductivity materials to reduce resistance and improve longevity.  We offer a wide variety of sizes and mounting patterns.  Common sizes are in stock and other sizes can be quickly made to order.

Engineering :

 

 

Obara USA is more than inventories and quick delivery.  Because of our years of experience and extensive knowledge of welding technology, many of our customers have requested custom design and manufacturing services.  Following along with our characteristically rigorous standards, Obara USA has made significant investments in the finest Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) systems.

Machining :

 

 

Obara’s North American manufacturing facilities have a wide range of equipment ready to fabricate all of the products required by our customers.  Standardized product designs have led to optimal use of Obara’s CNC equipment, including multiple horizontal and vertical multipallet machining centers.  Also, our cold headers and automatic lathes allow for quick deliveries on electrode parts.  Customized components are also easily machined with modular fixtures that are designed in-house by Obara’s production engineering team.  The engineering team makes full use of new machining technology to lower costs and improve lead times.

 

Training :

 

 

Obara’s customer support team can provide expert training for our entire line of resistance welding products.  Training sessions are held at the customer site to optimize trainee involvement and limit the amount of downtime.  The schedule and topics can be customized per the customers request or we can develop a suitable outline.  Possible topics include:
  • General resistance welding principles
  • Spot welding gun troubleshooting
  • Maintenance of spot welding guns
  • Programming Obara weld controllers
  • Motor replacement
  • Transformer testing

 

Repair :

 

 

Obara offers repair services for all of its equipment and any similar equipment.  Components are either repaired or replaced based on discussions with the customer, and the final product is shipped after a complete final inspection.  Services include, but are not limited to, adapter taper repairs, transformer repairs, and full weld gun rebuilds.  Obara utilizes an experienced staff of engineering, manufacturing, assembly, and inpection personnel to ensure the function and quality of the rebuilt component or assembly meets all required specifications.
