Fixed functions
A number of functions are fixed and cannot be
connected or disconnected from the control
panel.
Anti-freeze
The antifreeze function is always active. When
welding MMA or TIG it may occur that the
electrode sticks to the work piece. The machine
will register that the electrode sticks and it will
then decrease the welding current to 10 A which
make it easy to break the electrode off the work
piece. Welding can then be restarted as usual.
Pre-flow
Pre-flow is the period of time for which gas flows
after the torch switch is pressed and before the
HF arc is established. In the LIFTIG process the
period is the time until the torch is lifted away
from the work piece. Time is set to 0.1 sec.
Safety timer
If the welding arc hasn't been established after 2
sec., using contact-free striking in TIG mode,
then the machine is reset and the high voltage
generator is switched off.
MAINTENANCE
The machine requires periodical maintenance
and cleaning in order to avoid malfunction and
cancellation of the guarantee.
WARNING !
Only trained and qualified staff members can
carry out maintenance and cleaning. The
machine must be disconnected from the
mains supply (pull out the mains plug!).
Thereafter, wait around 5 minutes before
maintenance and repairing, as all capacitors
need to be discharged due to risk of shock.
Power source
- Clean the fan blades and the components in
the cooling pipe with clean, dry, compressed
air as required.
- A trained and qualified staff member must
carry out inspection and cleaning at least
once a year.
Warranty conditions
Migatronic continuously carries out quality control
throughout the manufacturing process as well as
check of the complete units through
comprehensive testing.
Migatronic provides warranty in accordance with
the following provisions, by correcting errors and
defects on units, that demonstrably and within
the warranty period may have been caused by
faulty material or workmanship.
The warranty period is 24 months for new
welding machines, 12 months for new
accessories and 6 months for spare parts. The
warranty period is calculated from the date of
invoice to the end user from Migatronic or
Migatronic's dealer/distributor. In the case of
sales through Migatronic's dealer/distributor, the
warranty period expires in any event within 36
months for new welding machines and 30
months for spare parts from the date of invoice
from Migatronic to the dealer/distributor. This
extension in no way extends the warranty period.
The original invoice is proof of the warranty
period.
Welding torches are considered as wearing
parts, and only errors and defects found within 6
weeks upon delivery and due to faulty material or
workmanship, will be considered under warranty.
Warranty repairs neither extend nor renew the
warranty period.
Any transport of goods or persons in connection
with a warranty claim is not covered under
Migatronic's warranty obligation and will
therefore be at the buyer's expense and risk.
