Description

Our Panasonic-style 500A heavy-duty MIG nozzle is the industry benchmark replacement for all genuine Panasonic 350A–550A water-cooled and air-cooled torches used in the world’s toughest welding environments. Precision-machined from thick, high-purity electrolytic copper and finished with a hard chrome plating layer, this nozzle delivers exceptional resistance to thermal deformation, spatter adhesion, and oxidation – easily outperforming ordinary copper or brass nozzles by several times in real-world high-amperage conditions.

The advanced internal geometry and carefully calibrated bore sizes ensure perfect laminar gas flow, creating a wide, stable shielding envelope that eliminates air entrainment and produces clean, porosity-free welds on mild steel, stainless steel, and aluminum even at currents exceeding 500A with 1.6 mm wire. Available in both conical and cylindrical shapes, welders can select the ideal profile for deep penetration fillet welds or wide-coverage flat-position work.

Trusted daily on automotive body-in-white lines, shipyard block assembly, bridge girders, offshore platforms, and fully automated robotic cells, these nozzles are recognized for dramatically reducing cleaning time, extending overall consumable life, and minimizing unplanned stoppages. Their robust construction shrugs off accidental impacts and maintains perfect concentricity throughout their service life.

Drop-in compatible with all standard Panasonic 500A torch bodies and gas diffusers – no adjustments required. Stocked in high volume and ready for immediate worldwide wholesale shipment.
