Over 40 years ago, Obara Corporation was founded to provide electrodes for resistance welding guns. Since our establishment, we have expanded our product line to include welding guns, transformers, timers, cables, and cylinders. Since 1986, Obara Corporation USA has established itself as a premier supplier of high quality welding supplies and services. With worldwide resources for welding equipment, auxiliary supplies, design and manufacturing services, Obara USA can meet your project's requirements, regardless of size or scope. Responding to the demands of a range of industries and an increasingly competitive marketplace, Obara USA has grown and diversified to offer full comprehensive support and a full range of services. We manufacture a large selection of welding guns, electrodes, cap tips, holders, shanks, adaptors, cables, shunts, and related products. Our ability to respond quickly and supply precisely the parts or equipment you need, has helped establish Obara USA as a world-class provider of complete solutions. Our establishment of branch offices throughout the country and Canada confirms our commitment to outstanding response, professionalism, and quality that has become Obara's trademark worldwide.

Because of years of experience and extensive knowledge of welding technology, many of our customers have requested custom design and manufacturing services. And with our characteristically rigorous standards, Obara USA has made significant investments in the finest Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) systems. Using these computer programs and a clear understanding of the materials and processes involved, our engineers can help design welding components to your specific requirements, often reducing the cost of your project. When you need technical support, our engineers are standing by to personally assist you with your welding system.

Servo Robot Guns Robot Guns Portable Spotwelding GunsThe latest in resistance weldingtechnology, the traditional pneumaticoperating cylinder is replaced by a servomotor connected directly into a driverunit which controls speed, pointpressure and stroke. This style of gunoffers a more flexible approach towelding. As of October 2000, Obara hasin excess of 15,000 servo guns invarious production plants around theworld.

Obara offers a wide range of robotwelding guns. Designs are based uponease of interchangeability, easymaintenance access and can bedesigned to meet individual customerrequirements.

Our long experience in the manufactureof portable guns together with the latestdesign and production technologyenables us to supply a low cost productwith improved durability and lightweight.

Holders Kickless Cables Air & Water Cooled CablesHolders are mounted onto gun arms anddesigned to have cap tips installed onthe other end. Obara’s holders can bemanufactured according to ourstandards or made to order.

Obara’s Kickless Cables arecharacterized by low impedance andhigh power. They are also designed toprevent premature breakage and toprovide superior cooling capacity

The advanced technologies of the wirestranding, terminal geometry, andcrimping methods result in superlativeresistance to wear, heat, and oil.

AC, DC, & Inverter Transformers Controllers Tip DressersEmploying high quality core materials,Obara provides both industry standardand custom designed high qualitytransformers. We recommend the useof our transformers on Obara robot gunsin this modern world where it's compactsize has become an indispensable factorin the ever advancing complication ofassembly lines in the automobileindustry.

Our Welding Controllers are user friendlyand have various features available suchas spatter regulation and variablepressurizing.

Obara's Tip Dressers are driven byelectrical motors so that the operationnoise is minimal. Thanks to the compactsize, installation in lines with limitedspace is possible.
