2. that weld spots are consistent, the production efficiency is high, the adjustment method is accurate, and the waste of the tin slag is reduce. Degree, front and back, left and right can be fine-tuned, tin feeding length, soldering time, etc. The welding gun is in high position, which can adjust the soldering tin temperature and discharge tin. 1.Automatic spot welding, automatic tin discharge, automatic Main Feature Brush the main characteristics of the soldering tin of the in-line components of the circuit board Application: DC brushless motor circuit board, printing station: single station JJD-2220C Station: Simplex Applicable: 3 ~ 2 Shade pole Poo.
