For the welding of stainless steel as SUS 309L etc.
THS-309L is MIG wire, THT-309L is TIG rod.
Characteristics:
THS-309L / THT-309L are the austenite stainless steel solid wires. Have perfect welding performance, stable and soft arc, beautiful appearance. All positions is suitable.
Attention:
1. The rust, oil, water and other impurities of the weld area must be removed before welding.
2. The shield gas should be THS-309L is with Ar + (1%-3%)O2, THT-309L is with pure Ar.
