Difference between automatic welding machine and semi-automatic welding machine

NB semi-automatic MIG welding (secondary welding), hand-held torch welding, secondary welding is not as frequent as manual arc welding in covered electrode, so it belongs to semi-automatic welding. Semi-automatic welding requires high welder technology, and the welding quality is completely realized by manual technology. ? NZ？ Automatic MIG welding (double-sided shielded welding), the welding gun can be welded automatically by an automatic welding trolley, or by a welding robot and a manipulator, and only personnel need to operate the equipment switch and control program, without holding the welding gun by hand. There are high theoretical requirements for welders, especially the matching and adjustment of welding parameters. Welding quality depends entirely on the adjustment of welding data.
