WSC Wire start control. This arc striking control device pre-
vents wire from sticking to the workpiece or torch nozzle
and ensures precise and smooth arc striking, particularly
when welding aluminium.
-
Welding parameters that are controlled digitally by a micro-
processor, are monitored and modified in just a few sec-
onds, maintaining a consistently precise and stable arc as
the welding conditions continue to vary due to the move-
ment of the torch and the irregularities of the parts to be
welded.
-
Exclusive SWS “Smart Welding Stop” system at the end of
TIG welding. Lifting up the torch without switching off the
arc will introduce a slope down and it will switch off auto-
matically.
-
“Energy Saving” function to operate the power source cool-
ing fan and the torch water cooling only when necessary.
- Auto-diagnostic feature for trouble shooting.
- Password-controlled total or partial equipment access.
• High electrical performance resulting in a reduction in ener-
gy consumption.
• Remote parameter adjustment directly from HT4 feeder.
Technical data
The general technical data of the system are summarized in
table 1.
Usage limits (IEC 60974-1)
The use of a welder is typically discontinuous, in that it is made
up of effective work periods (welding) and rest periods (for the
positioning of parts, the replacement of wire and underflush-
ing operations etc. This welder is dimensioned to supply a I
2
max nominal current in complete safety for a period of work of
40/50% of the total usage time. The regulations in force estab-
lish the total usage time to be 10 minutes. The work cycle is
considered to be 40/50% of this period of time. Exceeding the
work cycle allowed could cause a trip switch to trip (for further
information see the DH control panel manual), which protects
the components inside the welding machine against dangerous
overheating. After several minutes the overheat cut-off rearms
automatically and the welder is ready for use again.

WARNING: This equipment complies with EN//IEC 61000-3-12 provided that the maximum permissible system impedance Z
max
is less than or
equal to 0,037 Ω DIGITECH vision PULSE 3300 - 0,028 Ω DIGITECH vision PULSE 4000 - 0,017 Ω DIGITECH vision PULSE 5000 at the in-
