Pulse Overlay/Welding Machines for relatively small welding operations on the surfaces of moulds, dies and casting products. Advantages:
1. Easy Operation
2. Low-Heat Input (No distortion, stress, under-cut or oxidation)
3. Precision Overlay / Welding are possible (Reducing Finishing time & cost)
4. Possible to Overlay into narrow grooves, at the bottom face, side face. inner face & on the fillet of inside corner
5. No Pre-Heating & Post-Heating are needed. Disadvantage: Slow Overlay
