PRODUCTS / COPPER AND COMPONENTS
Welding machine electrodes
Working components for resistance welding. We select the design to suit the process, the material being welded and the joint geometry.
MANUFACTURING SCOPE
From requirement
to component.
Depending on customer requirements, we offer welding machine electrodes made from various material groups. The most commonly used are:
- Group A2 – copper alloys with high conductivity and moderate hardness, such as CuCr1, CuCr1Zr and CuZr. They are ideal for applications requiring high current conduction while maintaining suitable mechanical durability.
- Group A3 – alloys with higher hardness but lower electrical conductivity, such as CuCo2Be, CuCoNiBe and CuNi2Si, used under more demanding operating conditions.
- Group B – materials with exceptional wear resistance, such as tungsten, molybdenum and their alloys with copper, used mainly for welding highly electrically conductive components such as copper wires.
Our material variety and production flexibility allow us to offer electrodes suited to every type of welding machine and manufacturing process.

Electrode caps 2 items
Electrode caps
We stock a wide range of electrode caps in basic shapes according to DIN/ISO 5821 and 44750, as well as special shapes used mainly in the automotive industry.
We are the exclusive distributor in Poland of electrode caps from LUVATA SPECIAL PRODUCTS. LUVATA welding machine electrodes comply with DIN/ISO 5821 and 44750, but the variety of types and the option of using different materials mean that they carry additional designations for easier identification. The table below explains the designations of the individual electrode types and compares them with ISO/DIN descriptions.

Spot and projection welding electrodes
Spot welding electrodes are among the most commonly used electrode types in industry. They join metal components through local heating and pressure. Thanks to their high electrical conductivity, copper and its alloys are ideal materials for these applications. We offer spot welding electrodes made from group A2 copper alloys (grades CuCr1, CuCr1Zr, CuZr), characterised by high durability and excellent operating efficiency.
Projection welding electrodes are used in processes requiring simultaneous welding at multiple points or over larger surfaces. Their shape and operating principle are adapted to the particular application to ensure optimum results. In addition to spot welding electrodes, METALCON offers special electrodes incorporating advanced material combinations, such as group A2 and A3 copper joined to group B materials (tungsten, molybdenum, Elkonite) using silver brazing filler.
Spot welding electrodes play a key role in precisely joining thin sheets, ensuring high repeatability and process stability. With the right geometry and high-quality copper alloys, spot welding electrodes produce durable, clean and visually neat production welds even in intensive processes.

Nut projection welding electrodes 6 items
Nut projection welding electrodes. These welding machine electrodes are manufactured in three basic versions:
with insulation allowing ceramic pins to be replaced with steel or brass pins
with insulation and a sliding bush to extend electrode service life
insulation is not required when ceramic pins are used
Special electrodes with tungsten, molybdenum and Elkonite 2 items
Electrodes made from special materials (tungsten, molybdenum)
High-quality spot welding electrodes
Spot welding electrodes require high precision and materials with suitable physical and chemical properties from the manufacturing stage onwards. We therefore use only proven raw materials from reputable, qualified suppliers. Before entering our warehouse, all materials undergo rigorous quality control, including property testing, particularly hardness and electrical conductivity, with values specified in the material standards.
Welding machine electrodes are manufactured in accordance with industry standards or technical documentation supplied by the customer. Where documentation is unavailable, we can develop a design based on supplied samples or components. Our experience and individual approach to each order allow us to fulfil even the most unusual requirements.
Spot welding electrodes fulfil a key function in metal joining processes, as weld stability and the durability of the entire structure depend on their quality. Properly selected spot welding electrodes ensure suitable current conduction and optimum heat dissipation, resulting in clean, repeatable and strong joints. Our range includes different electrode types to suit the characteristics of the material concerned. The high-strength copper alloys we use to manufacture spot welding electrodes ensure resistance to wear and deformation even under intensive use. As a result, the spot welding electrodes we offer provide high operating efficiency and significantly reduce the maintenance costs of the entire production process.
