At lower current it has the opposite effect. The magnetic forces are smaller and are also
directed upwards. The droplet hanging at the tip of the electrode tends to increase in size
and the process runs the risk of being unstable. A way to overcome this problem is to
keep the arc length so short that the droplets will dip into the pool before they have
grown too much. Surface tension will then start the transfer of the melted material and
the tail of the droplet will be constricted by the magnetic forces, the so-called "pinch
effect".
