Our offered Intelligent ARC Welding Machine makes difficult downward welding of root passes easy. It offers a stable and focused modified short arc; this increases the quality of each weld. It is easier for less experienced welders to use the machine and carry out complex welds. Also, the welding speed increases in downwards welding of root pass compared to traditional upwards welding. Due to less heat input from the Intelligent ARC Welding Machine, the deformation is less of the welded material but offers sufficient penetration.
