FAQ and insights

The choice of electrode depends on several factors, including:

  • The type of material to be welded: copper, steel, aluminium, etc.

  • The thickness of the material to be welded.

  • The type of welding machine used: spot or roller.

  • The geometry of the piece to be welded.

  • The desired specifications for the weld: strength, durability, aesthetics, etc.

For an optimal choice, it is advisable to consult the data sheet of the material to be welded and the instructions of the welding machine. In case of doubt, it is advisable to contact a
welding expert.

Copper alloy electrodes offer several advantages over other types of electrodes, including:

  • High electrical and thermal conductivity: they ensure rapid heating and uniform welding.

  • Good wear resistance: they allow long life and a high number of welds.

  • Versatility: they are available in different shapes and sizes to meet the needs of any weld.

The following tips are recommended when using welding electrodes:

  • Clean the contact surfaces thoroughly before welding to ensure good electrical conductivity.

  • Check electrode clamping force for even pressure distribution.

  • Monitor the welding temperature to avoid overheating and defects.

  • Clean electrodes regularly from welding slag to maintain good efficiency.

  • Use original replacement electrodes to ensure optimum performance and safety.
