10. Disposal and recycling
The unit is supplied in packaging to prevent its being
damaged in transit. This packaging is raw material and
can therefore be reused or can be returned to the raw
material system.
The unit and its accessories are made of various
types of material, such as metal and plastic. Defective
components must be disposed of as special waste.
Ask your dealer or your local council.
If you want to continue a weld after an interruption, the
slag from your initial attempt must first be removed.
Overheating guard
The welding set is fitted with an overheating guard that
protects the welding transformer from overheating. If
the overheating guard trips, the control lamp (4) on
your set will be lit. Allow the welding set to cool for a
time.
9. Cleaning, maintenance and storage
Remove the power plug and wait until the fan has
stopped and the machine has completely cooled down
before performing any cleaning or maintenance tasks.
