5. Short-circuiting transfer welding conditions:
Welding conditions and application sphere of the short-circuiting transfer
Short-circuiting transfer welding conditions:
1. Low and moderate welding current;
2. Low arc voltage;
3. Shielding: CO2 or argon based mixtures.
Application spheres:
1. Welding of thin materials (due to a low heat input);
2. Out-of-position welding.
