* Defined as a plot of output voltage versus output current.
** Refer to the data plate on the rear of the plasma power supply for more information on duty cycle and for
IEC ratings.
*** WARNING: This Class A equipment is not intended for use in residential locations where the public low voltage
supply system supplies the electrical power. There can be difficulties in delivering electromagnetic compatibility in
those locations, because of conducted as well as radiated disturbances.
†
Equipment complies with IEC 61000-3-12 if the short-circuit power S
sc
is greater than or equal to 6,160 KVA at
the interface point between the operator’s supply and the public system. It is the responsibility of the installer or
operator of the equipment to make sure, by consultation with the distribution network operator if necessary, that the
equipment is connected only to a supply with a short-circuit power S
sc
greater than or equal to 6,160 KVA.
††
Equipment complies with IEC 61000-3-11 if the supply impedance, Zmax, is 0.201 or less. It is the responsibility of
the installer or operator of the equipment to make sure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with a impedance of 0.201 or less.

F5 recommended only for cutting stainless steel. Refer to Cut stainless steel with F5 in the
Powermax65/85/105 SYNC Mechanized Cutting Guide (810480).
