Thank you for having purchased our product. Please read in-
structions on use in this manual as well as the safety rules
10
given in the attached booklet and follow them carefully to get
the best performance from the equipment and be sure that the
11
parts have the longest service life possible. This manual will
11
show you the best way to do any maintenance jobs or repairs
eventually needed by your equipment to resolve any eventu-
11
al problems, we do however recommend our customers to ar-
range to have maintenance and eventual repairs done at our
11
servicing centres as they have the right equipment and the
11
highly qualified personnel is constantly updated. All our ma-
chinery and systems are subject to continual development.
12
We must therefore reserve the right to modify their construc-
tion and properties.

MULTI-FUNCTION INVERTER GENERATOR FOR MIG-MAG,
14
MMA, and TIG WELDING
The CONVEX vision series of multi-function equipments are
14
characterised by cutting edge, attractive design combined with
latest generation inverter technology and digital welding control.
14
Innovative, technologically advanced, robust, and easy to use,
15
they can be used for very high quality welding in MIG-MAG, us-
ing electrodes, and in TIG with "Lift" type ignition, and they rep-
16
resent the best solution for all industrial fields and all specialist
welding purposes that call for high precision and repeatable
16
results. CONVEX vision equipments, fitted with an innovative
synergic digital control, colour display, and the extraordinary VI-
16
SION-ARC meet the needs of those that wish to combine syn-
ergy with complete control of all welding parameters.
16
They come in a version with a separate feeder (HT4).
These are systems open to the future evolution of technology -
60
the control software can be kept up to date with the latest ver-
62
sions with the help of a personal computer.

Operating features
64
The main feature of the welding unit CONVEX 4000-5000 vi-
65-67
sion are:
• Metallic main structure with shockproof plastic front frames.
68
• Controls protected by a visor.
• Exceptional characteristics for MIG-MAG, MMA, and TIG
welding with "Lift" type ignition.
• Synergic digital control (VS) of all welding parameters, dis-
played via the innovative colour display, also featuring the
following functions:
- Allows less expert operators to regulate all welding param-
eters in a user-friendly way and extremely easily, choos-
ing the type of program on the basis of the material, wire
diameter, and gas used.
- Innovative "VISION ARC" software for controlling all weld-
ing parameters.
- With the special MIG torches you can adjust the welding
parameters at a distance straight from the torch.
- BURN BACK control. At the end of each weld, in any con-
dition and with any material, the digital control ensures a
perfect wire cut, prevents the typical "wire globule" from
forming and ensures correct arc restriking.
- 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 and short-circuits that are controlled
digitally by a microprocessor, are monitored and modified
in just a few seconds, maintaining a consistently precise
and stable arc as the welding conditions continue to vary
