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:
