Contact tips - FRONIUS

Contact peaks play an essential role in the transfer of electric current to the welding wire. This transmission is essential to form a welding arc that melts the base material and fuses the filler material to form a solid and reliable weld. Contact tips must be made of high quality materials that can withstand high temperatures and mechanical wear. The most commonly used materials include copper and its alloys, which provide excellent conductivity and wear resistance.
The correct size and shape of the contact tips are critical for effective welding. Improperly selected or worn tips can cause problems such as irregular arc, overheating or poor current transfer, which can lead to poor quality welds and increased material consumption. The quality of the contact tips directly affects the stability of the welding arc and the consistency of the welding process, so it is important that the tips are regularly inspected and replaced when necessary.
