SIMPLICITY AND EASE OF USE
Linear setting of the
welding current
Large and bright
displays for perfect
visibility
4 weld times plus
upslope and pulsations
Clear and standardized
symbols for easy
programming 2 programs
Single spot or continuous
welding
Programming could not be easier :
1 Select the parameter
2 Choose the proper value
3 Weld (program validation is automatic)
This visual programming avoids confusion and mistakes, thus time and productivity losses. In addition, the
actual welding current is proportional to the request, simplifying the search for proper settings.
squeeze time 0 - 99 periods
welding time 0 - 99 periods
weld current 10 - 99％ (linear)
hold time 0 - 99 periods

cold time between pulses 0 - 99 periods
􀁺 Mode without current : selection on gun or machine
􀁺 Squeeze without welding : selection on gun or machine

􀃂 2 models, 32 and 56 kVA at 50％ duty cycle,
share the same user interface, as well as most
components, therefore simplifying maintenance
and reducing spare parts inventory.
􀃂 With anti-vibration rubber feet, a transport
handle, and an optional side mounting kit,
installation is almost universal.
􀃂 Both 24 VDC and VAC electrovalves are
supported.
􀃂 Despite reduced dimensions, access into the case
is comfortable for fast maintenance.
􀃂 An optional front window with key lock provides
for increased protection and controlled
access to programming.
