Note: Voltage should be adjusted according to actual conditions; typical voltage range for 1.2–1.6 mm wire is 22–35V.

Note On Usage:

1.Apply CO₂ gas shield, and CO₂ gas purity should be above 99.98%.

2.The CO₂ shield gas flow during welding should be controlled between 18–25 L/min.

3.The extension length of the welding wire should be controlled between 15–25 mm.
