① strong wind resistance, the protective effect is good, as long as the wind speed does not exceed 11m / s. Are not required to take any protective measures. Particularly suitable for field construction work
② Welding wire is continuously fed, less weld joints, can greatly reduce the tendency of weld defects
③
Welding wire melting speed, high deposition efficiency and save energy. SMAW its power consumption is only 1/6 of about
④ Welding layer is thin, good slag, slag can greatly reduce the time. Conducive to the construction efficiency
⑤ Welding seam shaping and good internal quality appearance, anti-pores ability, small cracks tendencies
