2. The parameters should not be too high, especially the new welding tips.For each new welding tips, try to adjust the time to less than 12ms, adjust the voltage to below 0.90v, and then adjust the voltage according to the actual. We suggest that the time is generally about 10-12ms. When the new welding tip is tested, the parameters should be adjusted to about 0.80-0.90v. If the welding is not firm, then increase the voltage step by step. The time and pressure do not need to be changed frequently. The pressure can be between at 8-22 OZ.
