Up to 16 mm² Stranded wire and wire rope welding machines

STRECKER offers a comprehensive range of stranded wire and wire rope welding machines in the SE series.

SE welding machines are designed for the effective joining of stranded wires and conductor cables of up to 16 mm² made of aluminium or copper using tubes. With one clamping jaw for the complete welding range and the smallest possible single-wire setups for high-strength alloys, we meet the highest requirements, for example, for the automotive industry. Even wire ropes of different diameters can be welded. The result is a homogeneous, pore- and burr-free connection.

This process calls for the stranded wire or rope ends to be placed in a glass or ceramic tube so that the ends touch. Ceramic is the material of first choice here. Chamfering of the bore can be easily done on the machine. As a rule, we use glass tubes for a stranded wire diameter of < 1.00 mm.

After starting the welding process, the two ends are welded together by the current which then flows and the upset force which is applied. After the welding is finished, the tube is broken off in fractions of a second with the ergonomic STRECKER tube breaker. The surface at the weld is burr-free, clean, smooth and only imperceptibly thicker.

Operation of STRECKER welding machines is easy to learn. The foot actuation of the welding clamping fixture, which is standard in the SE series, meets the highest demands on convenience and ergonomics. Especially the LSZ series makes it possible to connect stranded wire apart from the customary welding position. The compact and robust machine design with intuitive operator guidance is designed for industrial use in production.

Every day, thousands of STRECKER welding machines are used worldwide to produce precise and repeatable butt welds.

From 25 to 2500 mm² Wire rope and cable welding machines

STRECKER offers a comprehensive range of wire rope and cable welding machines from the SE, PA, MS and MK series.

SE welding machines are designed for the effective joining of stranded wires and conductor cables of 25 to 1200 mm² made of aluminium or copper using tubes. We specify the exact clamping jaw required for each size or setup. This means that even with the smallest possible single-wire setups, we meet the highest requirements, for example, for the automotive industry. These machines are also found in front of extruder lines, as the optimal welding results with minimal thickening facilitate a smooth workflow. Even wire ropes of different diameters can be welded. The result is a homogeneous, pore- and burr-free connection.

PA welding machines command attention with their efficient design and construction. The manual clamping device with optimized ergonomics is the basis for this robust but also inexpensive version.

In SE as well as PA welding machines, the wire rope or cable ends are inserted into a tube made of ceramic or graphite until the ends touch. Ceramic is the material of first choice here. As a rule, we use graphite tubes from > 400 mm² (version G).

After starting the welding process, the two ends are welded together by the current which then flows and the upset force which is applied. Optionally, preheating is carried out to achieve an optimal temperature profile. After completion of the weld, the tube is broken off. The surface at the weld is burr-free, clean, smooth and only imperceptibly thicker.

Operation of STRECKER welding machines is easy to learn. The pneumatic welding clamping fixture is standard equipment starting with the SE12 and meets the highest demands in terms of convenience and ergonomics (the same applies for the PA100-SE). The upset pressure is then also pneumatic. The compact and robust machine design with intuitive operator guidance is designed for industrial use in production.

MS and MK welding machines are designed for larger cross-sections, the highest quality and documented reproducibility with wire ropes and cables of up to 2500 mm² made of aluminium or copper. We meet the highest requirements for the smallest possible single-wire setups, class 2 to class 6 applications, as well as for high-strength alloys. Even wire ropes with different diameters can be welded with a minimized heat-affected zone. The burr is removed in the welding clamping fixture and caught in the machine. The result is a homogeneous, very thin and pore- and burr-free connection. The MS and MK series are equipped with our innovative FullParameterControl (FPC) control system as standard. The complete welding recipe is stored safely and with accurate repeatability in the controller. All settings of the machine are made automatically according to the recipe selected with no operator intervention. As an option, the quality of the welding process can be monitored with the STRECKER parameter monitoring system.

A 3-phase direct current transformer is employed to counteract the high current consumption or short-term peak load that occurs when welding very large conductor cable cross-sections. This reduces the current consumption.

Every day, thousands of STRECKER welding machines are used worldwide to produce precise and repeatable butt welds.
