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 posi-
tioning of parts, the replacement of wire and underflushing opera-
tions etc. This welder is dimensioned to supply a I
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 considered to be 50% of this
period of time. If the permitted work cycle time is exceeded, an
overheat cut-off occurs to protect the components around the welder
from dangerous overheating. Messages flashing on the display will
warn you when the heat safety device starts working (see para-
graph "Error conditions"). After several minutes the overheat cut-
off rearms automatically and the welder is ready for use again. Do
not weld in the rain. This generator is constructed in compliance
with the IP23 protection level.

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.
DIGITECH 400 PULSED
The welder has two handles to carry it around manually.
TA4
The wire-feeder has a handle and a hook so that it can be hung up.
WARNING: For safety's sake, add an extra attachment to the
handle when hanging up the wire-feeder by its hook.
NOTE: The lifting and transporting devices conform with Euro-
pean regulations. Do not use other equipment to lift or transport
the feeder.

Opening the packaging

The system essentially consists of:
• Weld unit (DIGITECH 400 PULSED);
• Wire-feeder unit (TA4);
• MIG-MAG welding torch ;
• Wire-feeder/generator interconnection cable;
• Coolant unit for welding torch (HR26) (optional);
• Trolley to carry it around (CT 40) (optional).
Perform the following operations on receiving the apparatus:
• Remove the welding generator and all accessories and compo-
nents from the packaging;
• Check that the welding apparatus is in good condition; otherwise
immediately inform the retailer or distributor;
• Check that all the ventilation grilles are open and that there are
no objects obstructing the free flow of air.
The installation site for the system must be carefully chosen in
order to ensure its satisfactory and safe use. The user is responsi-
ble for the installation and use of the system in accordance with
max nominal the producer's instructions contained in this manual. Before install-
2
ing the system the user must take into consideration the potential
electromagnetic problems in the work area. In particular, we sug-
gest 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
Persons fitted with pace-makers, hearing aids and similar equip-
ment must consult their doctor before going near a machine in
operation. The equipment's installation environment must comply
to the protection level of the frame.
The welding unit is characterized by the following classes:
• IP 23 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 (optional);
• Attach the welding unit to the trolley;
• Assemble the wire-feeding unit onto the trolley;
• Attach the coolant unit (optional) to the trolley and to the welder
(electrical and water connections).
• Connect up the wire-feeder/generator interconnection cable;
• Connect up the welding cables;
• Connect up the welder to the mains.
Assembly instructions for each single optional are in special pack-
ing.
