due to the movement 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.

positioning of parts, the replacement of wire and underflush-
ing operations etc. This welder is dimensioned to supply a I
max nominal current in complete safety for a period of work of
50% of the total usage time. The regulations in force establish
the total usage time to be 10 minutes. The work cycle is con-
sidered to be 50% of this period of time. Exceeding the work
cycle allowed could cause a trip switch to trip (for further infor-
mation see the VS 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.
How to lift up the system
Strap the system safely and securely in the slings working from
the bottom, then lift up from the ground.
This welding machine has a robust handle built into the frame
for moving the equipment.
NOTE: These hoisting and transportation devices conform to
Table 1
European standards. Do not use other hoisting and transpor-

Opening the packaging
400
The system essentially consists of:
• CONVEX 4000-5000 vision weld unit.
25,6 • Separately:
- HT4 wire-feeder unit (supplied separately).
35
- MIG-MAG welding torch (optional).
- Wire-feeder/generator interconnection cable (supplied sep-
0,89
arately).
70
- HR 30 coolant unit for welding torch (optional).
- CT 70 trolley to carry it around (optional).
Perform the following operations on receiving the apparatus:
380
• Remove the welding generator and all accessories and com-
460
ponents from the packaging.
500
• Check that the welding apparatus is in good condition; other-
wise immediately inform the retailer or distributor.
• Check that all the ventilation grilles are open and that there

is nothing to obstruct the correct air flow.
Installation and connections
The installation site for the system must be carefully chosen
in order to ensure its satisfactory and safe use. The user is re-
sponsible for the installation and use of the system in accord-
ance with the producer's instructions contained in this manual.
Before installing the system the user must take into consider-
ation the potential electromagnetic problems in the work area.
In particular, we suggest that you should avoid installing the
system close to:
• Signalling, control and telephone cables.
• Radio and television transmitters and receivers.
• Computers and control and measurement instruments.
• Security and protection instruments.
43
Persons fitted with pace-makers, hearing aids and similar
equipment must consult their doctor before going near a ma-
chine in operation. The equipment's installation environment
must comply to the protection level of the frame.
is less
The welding unit is characterized by the following classes:
max
• IP 23 S protection class indicates that the generator can be
used in both interior and exterior environments.
• The "S" usage class indicates that the generator can be em-
ployed in environments with a high risk of electrical shocks.
This system is cooled by means of the forced circulation of air,
and must therefore be placed in such a way that the air may
be easily sucked in and expelled through the apertures made
in the frame.
Assemble the system in the following way:
• Assemble the trolley.
• Fixing the cooling unit to the trolley.
• Fixing of the welding machine to the trolley and the cooling
unit (electrical and plumbing connections).
