Purpose：
For welding important low carbon steel structure and low strength grade low alloy steel structure, such as Q235,09MnV, 09Mn2 and so on.
Features：
J422 is a carbon steel electrode with titanium coating. AC, DC dual-use, all-position welding. Excellent welding process and mechanical properties; arc stability, small spatter, easy slag, easy re-arc; beautiful weld shape, welding wave can be wide, narrow, thin, thick, easy welding, efficient.
Points to note：
In general, do not bake before welding. The electrode must be baked at 150-170℃ for 0.5-1 hour after being wet.
Welding position：
