Tips

For optimal results, use a shielding gas mixture of Ar/18%CO2 for spray arc transfer or 100% CO2 for short circuit welding. Ensure proper storage in a dry environment to maintain the copper coating and prevent moisture pickup. Adjust wire feed speed and voltage according to material thickness and joint configuration.
