Warning: In environments with increased risk of electric
shock and fire, such as in the proximity of inflammable
products, explosives, height, restricted free moving
space, physical contact with conductive parts, warm and humid
environments that reduce the electrical resistance of human skin
and apparatus, observe the risk prevention in the workplace and
the national and international provisions as pertinent.
3.- Instruction for putting into operation
3.1.- Positioning
The machine must be positioned in a dry, ventilated area and
with a separation of at least 15cm from any wall. The equipment
may slip when supported on surfaces having an inclination of
more than 3º, so that it shall always be placed on a flat and dry
surface. When placing it on surfaces with a greater slope, secure
the machine with chains or belts. Avoid placing the equipment
when facing wetness or rain.
Avoid the entry of steel shavings into the machine's inside. Do
not use the grinder next to the equipment.
3.2.-Assembling
The equipment shall be assembled respecting its environmental
limits and positioning it correctly.
3.3.- Mains connection
The equipment is powered by the cable and connector provided
as standard, through a differential circuit breaker and a slow-
feature electromagnetic circuit breaker having an intensity in
accordance with the table of technical features. Any connection
must have a regulatory ground connection and comply with any
national electricity regulations.
In the case of a connection to a power generator, the power
requirements stated in the technical specification are to be
observed. It shall be taken into account that an equipment will
be able to operate with a generator providing less power than
the stated one, with the limitation to use it with a lower maximum
intensity than the nominal one.
3.4.- Limitations to environmental conditions
The equipment shall be installed respecting its IP21 class, which
means that the equipment is protected at the most against
vertical impact of water drops and access to dangerous parts
with one finger against solid 12.5 mm ø or larger foreign bodies.
The equipment is prepared for working within a temperature
range from -15ºC to 70ºC, taking into account the limitation of a
decrease in performance (duty cycle) as of ambient temperatures
above 40ºC.
4.- OPERATING INSTRUCTIONS
4.1.- Positioning and testing
All Steyer Welding machines of the series must be handled
using the handle which is arranged for transport.
A fee space of at least 15cm must be arranged around the
equipment, and free circulation of air must be secured for
correct heat dissipation. Before each work, good operation and
correct tightening of all external elements of the equipment shall
be verified: power supply plug, cable, housing structure and
connection terminals and switches.

4.2.- Tool changing
All Steyer Welding machines of the series have a 1/2 inch DINSE
quick connector for the welding cables. To remove or put the
connector on, it is sufficient to turn the connector a quarter turn
leftward or rightward.
WARNING: Always connect the DINSE connector as
far as it will go and make sure that the splice with the
cable is in a good condition and that the contact surface
is clean. A bad splice or a dirty connection will result in a bad
performance and make the front panel to become overheated,
fused or burnt.
4.3.- Setting operations
All Steyer Welding machines contain a complex electronic system
and come completely calibrated ex works, so that, for the sake
of efficiency and safety, it is not authorized to be manipulated by
the user. In case of any doubt regarding a malfunction, contact
your distributor or our helpdesk system.
4.4.- Limits regarding the size of the workpiece
The main restriction regarding the size of the workpiece is its
thickness which is limited by the power of the equipment. With
more power, you may carry out accurate welds (with suitable
penetration of the welding bead) in pieces having a higher
thickness. The following table may serve you as an orientation:
