1 GENERAL DESCRIPTION
Connects to any primary voltage between 380 and 440V without need for any action from the
operator.
Line Voltage compensation keeps output of the power source constant regardless of fluctuation in
input power from 10% below lowest to above highest rated input voltage.
Safe in use. Touchable Open Circuit Voltage only 9V, well below the 70V limit set by the Code of
Safe Working Practices for Merchant Seamen.
Automatic Hot Start for stick arc starts makes arc striking easy and prevents electrode sticking.
Adjustable Arc Force for stick electrode welding allows the arc characteristics to be changed for
specific applications and electrodes.
Lift-Start in TIG mode provides easy and soft TIG arc starting.
Step-less adjustment of welding current through whole current range: 10
–320A.
Casing of high grade aluminium and industrial plastic to eliminate corrosion damage also contributes
to low-weight which together with compact outer dimensions provides good portability.
Wind tunnel design for the internal cooling air flow protects electrical components and PC boards
from dirt, dust, debris, greatly improving reliability.
Thermal overload protection with indicator lights helps prevent machine damage if the duty cycle is
exceeded or airflow is blocked.
Total Protection function with indicator light prevents machine damage if one phase in the primary
power supply falls out.
