What is the use of the nozzle gel in MiG welding?

In MIG welding, nozzle gel is used to prevent spatter from adhering to the nozzle and to improve the overall welding process. It creates a protective barrier that helps maintain the cleanliness of the nozzle, enhancing the efficiency of gas flow and shielding the weld area from contamination. This results in cleaner welds and reduces downtime for maintenance or cleaning. Additionally, it can extend the life of the nozzle by minimizing wear and buildup from molten metal spatter.
