- Only use electrodes that are recommended for the machine (see spare parts
list) without altering their shape.
- RISK OF BURNING
Someofthespotwelderparts(electrodes-armsandadjacentareas)can
reach temperatures of above 65°C: suitable protective clothing must be
worn.
Allownewly-weldedpiecestocoolbeforetouchingthem!
- RISK OF TOPPLING AND FALLS
- Place the spot welder on a horizontal surface that can suitably support the
mass; constrain the spot welder to the supporting surface (when indicated
inthe“INSTALLATION”sectionofthismanual).Incontrarycases,where
theooringisslopedorbroken,orwithmobilesupportingsurfaces,the
danger of toppling exists.
- It is forbidden to lift the spot welder, excluding where expressly indicated in
the“INSTALLATION”sectionofthismanual.
- When using machines on wheels: disconnect the spot welder from the
electric and pneumatic (if present) power supplies before moving the unit
to another work area. Pay attention to obstacles and unevenness on the
ground (for example cables and piping).
- UNINTENDED USE
It is dangerous to use the spot welder for any purpose other than that for
which it is intended (see INTENDED USE).
SAFEGUARDS AND SHIELDS
The safeguards and mobile parts of the spot welder casing must be in position,
before connecting it to the power supply.
WARNING!Anymanualinterventionontheaccessiblemobilepartsofthespot

- Replacement of or maintenance on the electrodes
- Adjustmentofthearmorelectrodepositions

STORAGE
- Place the machine and its accessories (with or without packaging) in closed
areas.
- Therelativehumidityoftheairmustnotexceed80%.
- The environmental temperature must be between -15°C and 45°C.
If the machine has a water cooling unit and the environmental temperature is
lower than 0°C: add the indicated antifreeze liquid or completely empty the
hydraulic circuit and the water tank.
Always use suitable measures for protecting the machine from humidity, dirt
and corrosion.
