Who can tell how many volts are needed for the two welding voltage of the welding machine. The weldment is wall thickness 1.5mm diameter 21mm round tube T type butt joint. How many ampere current is needed?
Normal connection, general 10-12V reverse connection, general 24V up and down
Two no-load voltage, ranging from 4-12V. The power is large and the load is high. In general, 5-10A current per square millimeter is required.
7-8V or so, what is butt welding and flash butt welding?
