JEC Swing Arms
July 16, 2020
JEC has the right Copperhead product to meet all your cap dressing needs.
The E2L Electrode Dressing System configured with the Swing Arm (SP6 or SE8) offers a wide variety of reshaping applications. The machines consist of a milling system, axial compensation, chip removal, electric, pneumatic or servo drives and optional electronic controls. The dressing system is presented to the application by the Swing arm offering precise positioning to the application. An optional balancing lift system is available to equalize the dressing unit between the electrodes.
JEC has a complete line of Copperhead water management solutions to offer their customers.
The Copperhead Water Block offers water temperature monitoring, water flow monitoring and a water shut off valve all in one compact solution. The Copperhead Water Retract Actuator works in conjunction with the Water Block to hold back water from escaping your closed loop system when the welding caps are removed during cap change.
For a turnkey solution, the Water Block and the Water Actuator come already mounted and connected on a back plate. The system comes completely connected with shutoff valves for a quick simple installation.
JEC wants to supply and integrate these products individually or as a complete package for you. We want to help you control your water to provide a safer work environment and extend the life of your equipment while saving you money.
We are pleased to announce a new product offering targeting stamping process improvements. Copperhead has developed a new sheet metal pallet loading system that is universal in design and allows for multiple sizes of cut sheet metal to be accommodated. This new design also provides safety enhancements from current processes for plant personnel utilizing a foldable corner post application which also saving you storage space. Other features include an increased rigidity of the pallet floor to maximize payload capacity, elimination of finger pinch points and elimination of repetitive heavy lifting. This design incorporates the use of adjustable vertical octagonal stanchion posts that allow for one pallet to accommodate multiple metal configurations required using only one pallet design. Make your process safer, more efficient (reduce time / space) and reduce your scrap costs by converting your process to our new design.
We are pleased to announce a new product offering complementing our already award-winning existing product line. Introducing the CEC1 (Copperhead Electric Changer), built in North America. This is a powered cap changer that is offered in many various motor voltage variants as well as a pneumatic driver version. The CEC1 is available in the vertical or horizontal mount orientation and is light enough to even mount on a robot end effector without affecting the payload. The quick lock pin engagement system makes magazine assembly exchanging fast and easy. Magazine assemblies are error proofed with an advanced poke yoke system that makes it impossible to load the wrong cap type magazine on the wrong changer. The changer is available in a single or double magazine system which extends the number of caps held up to 52 caps. This feature can increase your production run time as well as give you the option for having 2 different robots share one changer.

We would like to bring to your attention some exciting new product information. We are pleased to announce that our North American built mechanical cap changer has a new name, new look and enhanced performance features. Formerly known as the MKW308, the new name is now the CMC3 (Copperhead Mechanical Changer). The new look of the CMC3 is sure to stand out on your shop floor. This change coupled with some engineered part enhancements are sure to optimize your cap changing experience. Considering our customers with existing legacy equipment, all new changes have been engineered in a way to still be compatible and interchangeable with the previous versions of the MKW308. In addition to these base model changes, we have also created a new style enhanced magazine cartridge called the M1 model.

RSWA is an ultrasonic device designed for quality control and NDE of resistance spot welds. RSWA is as a portable and simple-in-operation device capable of producing images of spot weld’s internal structures. In addition to live on-screen image, this device performs estimation of the nugget diameter and compares it with predefined minimum nugget requirements. Using the unique technology of multi-channel ultrasonic matrix transducer, RSWA collects data from the surface and from the internal structures of the nugget. Special algorithms use this data to reconstruct the image of the spot weld and estimate the average diameter of the nugget area in real time.
Features:
◾single-frame and continuous data acquisition modes
◾automatic and manual nugget size estimation
◾automatic detection of scanning depth inside the metal
◾built-in reporting system and file storage
Applications:
◾Metal stacks: 2T and 3T; 0.6–2.4 mm plate thicknesses
◾Types of materials: mild steel, high strength steel, dual phase ultra high strength steel
◾Coatings: bare, zinc coating (galvanized, galvaneal), e-coating, paint
Water Saver/Tip Loss Monitor and Water Retract Actuator
May 1, 2017
All too often when changing welding electrodes the person removing the caps is immediately splashed with cooling water from the weld gun.
If this has happened to you, then you know this type of water is usually pretty nasty! It could also be treated with expensive chemicals to inhibit corrosion and improve cooling so losing it on the floor is not the best solution.
Another scenario for water loss is in the case of a broken water hose, cracked adapters or electrode cap sticking to a part and being pulled off the weld gun when the robot retracts.
We can address both these situations with our line of Copperhead products, in this case our:
“Water Saver/Tip Loss Monitor and Water Retract Actuator”
For more information, check out our WaterSaver System.
In resistance welding the copper electrode, cap or tip is in contact with the material being welded. High current is passed through the weld gun causing the material being welded to become molten. When the current is stopped, the weld gun remains closed long enough for the material to solidify and bond together.
Through this process the copper electrode, cap or tips as they are most commonly known, can become “mushroomed”. When the cap face becomes larger something must be changed in the weld setup in order to maintain the required nugget size.
One of the best solutions is to dress the copper tips back to their original size and shape with a Copperhead brand Tip Dresser.
We can supply solutions for single station tip dressing, cutters and holders for any brand machine you currently have as well as special units that contain the tip dresser and patented automatic cap changer on a single stand.
