NOTE:
- Shield gas: Must ensure not to operate with impurity shield Gas.Recommendation Rate of mixed gas: Ar+1-3%O2.
- Operation flow rate of shield gas: 20-25L/min.
- Electrode extension: 15-25mm
- The welding should be operated in clean surface without rust, moist, oil contamination and dust.
- Prevent affected of wind when wind speed reach 1.5m/s to avoid bubbles generated.
The above suggestions are for reference purpose. Evaluate and determine the situation of the scene before starting the wielding process.
