How can the argon arc welding machine adjust the operating voltage range?
When the argon welder is constant current, the operating voltage varies with the operating current, and no adjustment is needed. If the work voltage is changed forcibly, the welding machine will not work properly
Argon arc welding machine can only set current, the voltage is determined by the arc length, that is, the distance between the tungsten electrode and the workpiece.The current determines the depth of penetration, and the voltage determines the width.
