2. Product Performance Advantages
2.1 Welding Process Performance
Strong Arc Stability: The arc burns evenly and concentratedly during all-position welding, accurately controlling the shape and depth of the molten pool, and effectively avoiding defects such as incomplete fusion and pores.
Low Spatter and Low Smoke: The unique coating formula reduces spatter rate, with small spatter particles, reducing post-welding cleaning work; smoke emission is lower than similar products, improving the working environment.
Convenient Arc Striking and Restarting: The arc can be quickly reignited after breaking. Stable welding can still be maintained on the surface of damp or slightly rusted base materials, enhancing the reliability of on-site construction.
