MIG automatic welding is always broken arc is how ah?
The description of the problem is too vague. What is the phenomenon of arc breaking?Two possibilities:1. current voltage is relatively large, but not to melt the wire too fast, there will be a section of a wire melted, intermittent arc2., feeding wire interruption, arc back to the wire feeder, because the discharge distance is too large, resulting in arcing
There are several reasons for arcing:First, the power load capacity is poor.1, power line is too long, too small;2, the power supply voltage is too low, two, welding machine itself problems1, secondary current adjustment is too small, and the diameter of the welding rod does not match.2, each node serious corrosion, bad contact.Three. Welding rod quality problem.1, welding rod itself quality is slightly lower,2, welding rod damp, medicine skin deterioration or failure.
Two possibilities:1. voltage current is too large, is the wire too fast but not to melt, there will be a section of a wire is melted, and the arc (conductive mouth there is no welding slag sticking often? If so, that's why.)2., feeding wire interruption, arc back to the wire feeder, because the discharge distance is too large, resulting in arcing
