The LWG-5200 is an intelligent, precision electric spark welding repair machine. It adopts dual-MCU precise control and dual-stabilized inverter high-frequency switching power supply. Based on electric spark deposition technology, it realizes fast defect repair and surface strengthening of metal workpieces. During welding, the base material will not deform or anneal, with high repair accuracy and strong bonding strength. It is widely used for cast steel, cast iron, cast copper, cast aluminum and various metal materials, which is a professional choice for mold, casting and mechanical parts defect repair and surface performance improvement.
Key Selling Points
Zero Damage to Base MetalNo preheating needed; instant heat input and dissipation ensure no deformation, no annealing, no undercut, no residual stress.
High-Quality Welding ResultSame material with low-temperature welding provides almost no color difference, smooth welding spot, no hard spots, friendly to secondary machining.
Strong Metallurgical BondingIonized welding material infiltrates the substrate, featuring high bonding strength, no peeling, no cracks, no porosity.
Wide ApplicationWorks for ferrous and non-ferrous metals; excellent performance on copper, aluminum and other high-conductivity materials.
Stable & EfficientDual-stabilized inverter power supply with efficiency up to 95%+, stable output, fast welding speed.
Precise Digital ControlDual MCU + digital CPU control for accurate discharge and fine parameter adjustment.
