• Applications
• Butt and fillet welding of steel structures such as vehicles, machinery and bridges.
• Characteristics on Usage
• • - WM-70 is a solid wire designed for all position welding by short-circuiting type transfer.
  • - As the deposition efficiency is high and penetration is deep, highly efficient welding can be performed.
• Notes on Usage
• • - Shielding gas should be used 100%CO₂, Ar+20~25% CO2.
  • - Use wind screen against wind.
  • - Keep distance between tip and base metal 6~15mm for less than 250A, and 15~25mm for more than 250A of welding current.
