The Fronius 42.0001.3975.5 is a high-performance contact tip (often referred to as a current nozzle or Stromdüse) designed for demanding MIG/MAG welding applications. Engineered with the precision characteristic of Fronius manufacturing, this consumable is critical for maintaining a stable welding arc and ensuring consistent wire feeding. The tip features a robust M8 x 1.5 thread, which provides a substantial contact area for electrical transfer, minimizing voltage drop and heat generation at the interface.
With a geometry defined by SW 11 (11mm wrench size) and a length of 44.5mm, this tip is tailored to fit specific Fronius torch bodies, such as the AL (water-cooled) and AW series. The use of high-quality copper alloy (typically CuCrZr) ensures that the tip retains its hardness even at elevated temperatures, resisting the keyholing effect that causes arc instability. This makes it an ideal choice for automated or high-duty-cycle manual welding where reliability is paramount.
Proper maintenance of the contact tip is essential for weld quality. A worn tip can lead to micro-arcing inside the bore, erratic wire feeding, and burn-backs. By using genuine Fronius consumables, operators ensure that the tolerances of the inner bore match the wire diameter perfectly, providing optimal current transfer and arc starting characteristics. This pack contains 5 units, allowing for convenient stock replenishment.
