1. The wrong welding practices can easily lead to poor melting wire, protective lens contamination, poor welding results, etc.;

2. A reasonable basic differential setting can optimize the welding effect, with the appropriate wire feeding speed, power can enhance the smoothness of the broken wire;

3. The appropriate gas out, off the gas delay can protect the lenses, increase the power ramp-up time can be optimized just out of the light when the energy phenomenon of over-strength, increase the power ramp-down time can be optimized. Optimize the effect of silk breaking (not recommended more than 200ms).
