Lincoln Positive Contact Nozzle Assembly for 5/32-3/16 Wire - K148B

The Lincoln Electric K148B contact nozzle is a top - choice for high - current welding. It's a positive contact nozzle assembly designed for 4.0 - 4.8 mm (5/32 - 3/16 in) diameter wire. When welding at high currents, especially over 600 amps with Innershield welding, we recommend an optional water - cooling attachment for optimal performance.

Using this Lincoln K148B contact nozzle is easy. First, make sure you've selected the right 4.0 - 4.8 mm diameter wire for your welding job. Install the nozzle securely on your welding equipment. When you start welding at high currents, keep an eye on the heat. If you're welding over 600 amps with Innershield, attach the water - cooling system for better results. After each use, turn off the power and let the nozzle cool down. Clean it regularly with a soft brush to remove any debris. Store it in a dry place to prevent rust and damage.
