Welding Notes
Clean oil, rust, moisture and contaminants from the weld area before welding.
Maintain stable wire feeding and an appropriate arc length during welding.
Proper shielding gas flow is recommended to ensure stable arc performance and weld quality.
Avoid excessive heat input to minimize distortion.
Select suitable welding parameters according to material thickness and joint design.
