1. Drying Requirements: Welding electrodes must be heated to 300°C for 1 hour before welding and used immediately after drying.
2.Power Supply Selection: DC reverse polarity (DC+) is recommended for better arc stability and weld formation. AC can also be used if necessary.
3. Welding Operation Tips: Adopt low current and short arc during welding. Avoid excessive oscillation amplitude to ensure uniform weld formation. For vertical/overhead welding, reduce current appropriately to prevent molten metal from sagging.
