selection (no manual setting of pressures, capacities and times); complete functionality identical to Strecker V20 weld/anneal control; primary voltage compensation for unstable mains supply systems; secondary voltage calibration to harmonise operation of several welding machines in the same factory; and monitoring of relevant welding parameters for quality recognition and documentation. The second generation of controls o ers constant current control (KSR/50Hz over 60Hz) to reduce the in uences on the weld quality due to temperature, contact, material or cutting quality. Especially important for welding large quantities, it o ers zero-gap adjustment of the clamping tools to each other, so there is no need for regular review or setting of the air gap to optimise the deburring result, all of which provides for a longer lifetime of the jaw inserts. The elds of use are diverse, involving welding solid wires or rods directly at the wire feed to ensure continuous production, or joining di erent classes of stranded products (class 2 to class 5, for example), or even stranded to solid material or shaped parts to strips, etc. These models can be adapted to cover mass production in the clients’ manufacturing lines, performing welds every 15-30 seconds, depending on material/dimensions, in shift operation and self-su cient. The machines are manufactured with a high grade of automation, and are fast and reliable, with high accuracy and repeatability. Especially for bigger wire rod sizes of 20mm diameter or above, the physical limits of what the operator is capable of are reached, even when using such a comfortable machine. Consequently, Strecker designed a handling device for large diameters on a welding machine with vertical orientation of the wire axis. The wire ends are pulled out of the coil one at a time and then positioned in the clamping device for welding. The entire process is then controlled manually by an operator manually, but without the use of physical force or bodily exertion. Automated handling is available to reduce the period of time the operator has to spend with the welding machine. Here, the gripping arms of the handling device are brought to the wire rod ends to be welded and these are clamped into the grippers. The operator presses a key to start the automatic process. The grippers pull the two wire ends into the clamping device for welding, the ends

One of Sjogren’s simple yet revolutionary innovations is in the grooved roll market, with its alignment marker that delivers precision and reduced wear and downtime. The simple idea is that to control precision, you need to control the centreline. The Sjogren alignment marker accounts for variations in bearing width and makes it easy for the operator to identify the correct way to mount replacement rollers to maintain tolerances. Controlling the centreline ensures the wire does not scratch or bend.

➢➣➢ The company will introduce technical solutions for CV tube components, and heavy-duty cable jacketing and submarine cable equipment will be exhibited. Machinery will be on full display, including the Trendseal variable cable seal for continuous vulcanisation, advances in Industry 4.0, true triple extrusion crosshead TQU, continuous screen changer and a functional continuous kneader. In 1892, the German engineer Paul Troester started building machines which could process unvulcanised rubber and gutta-percha. After 125 years, the company is now known as a reliable extrusion partner and supplier of machines and lines for the cable manufacturing industry. At Interwire, Troester will present a variety of information and new developments in the eld of high and extra-high voltage CCV lines and VCV lines for XLPE and rubber cables, one-step silane lines for LV and MV cable applications, as well as high-speed insulation and sheathing lines, including building wire, automotive, oil and gas, renewable solar and windfarm, electronics and exible cord applications. are clamped, welded, deburred, and the clamping device opens up again. The welded wire coil ring stays clamped in the upper gripping arm to avoid any uncontrolled tripping of the wire. Depending on individual requirements, in close cooperation with specialised sub-suppliers Strecker also provides solutions to the problem of automatic material feed to the buttwelder. The welders are equipped with all interfaces and sensor systems required for communication with the placement machine or the manufacturing line.

All Sjogren straighteners use grooved rolls machined to exact speci cations and feature its alignment marker, which ensures the assembly maintains a precise wire centreline. Sjogren’s series of straighteners o er either a quick-release lever with locking handle or a non-quick-release feature, depending upon the application. The quick-release mechanism is best used for easy opening without a ecting roll adjustments. Eliminating roll set-up adjustments minimises set-up time, increasing productivity and pro tability. Whether the manufacturer’s straightener assembly, Sjogren can provide replacement grooved rolls that will work in the current con guration.

Germany’s August Strecker GmbH & Co KG reports a great step forward for its dual upset buttwelders with automatic deburring, in particular the company’s control technology Full-Parameter- Control (FPC), the latest developments being the FPC EVO2 and FPC EVO2 Zero Gap models. The rst generation was noteworthy for easy and safe storing of customer-speci c or material-speci c welding recipes; menu-guidance, easy-to-understand in a number of di erent languages; improved quality by xing programs with automatic
