Lincoln Electric Promig 300 (AIR) Contact Tips (10 Per Packet)

Features:

• CuCrZr contact tips bring excellent performances compared to standard copper contact tips (Cu).
• The electrical conductivity being superior in a CuCrZr alloy, the arc transfer will meet less resistance and the contact tip will wear out less rapidly.
• The mechanical and thermal resistances also being superior to a copper alloy, the constraints, especially due to the wire friction and to the arc temperature, will be better tolerated with a CuCrZr contact tip.
• Used in robotic welding for these advantages, the CuCrZr contact tip can improve the manual MIG/MAG welding performances as well.
