Abstract
The invention relates to a contact tip for a welding or cutting torch which includes at least one internal opening for guiding and engaging at least one welding electrode, wherein the internal opening is produced by deep drilling in a bar-shaped semi-finished product, such as a solid material. The use of drawn semi-finished products can thus be eliminated, thereby widening the range of material selection and reducing the cost of the semi-finished product.
