Precautions:
- Shielding gas: pay attention to the purity of shielding gas, it is recommended to keep the mixed ratio at Ar + 1~3% O₂.
- Gas flow: 20~25L/min.
- Dry extension length: 15~25min.
- The rust layer, moisture, oil stain, dust, etc on the welding part shall be clearly removed.
Welding Position: H, OH, HF, F, VD, VU
