Maintenance - Migatronic PI 200 MMA Manuel D'instructions

Arc-power
The arc power function is used to stabilise the
arc in MMA welding. This can be acheived by
increasing welding current during the short-circuits.
The additional current ceases when the short circuit is
no longer present.

circuit
Arc power can be adjusted between 0 and 100% of
the welding current setting.
E.g. If the welding current is set to 40A and arc
power to 50% the additional current is 20 A
equals 60 A when doing arc power. If the arc
power is set to 100% the additional current is 40
A equals 80 A when doing arc power.
Internal/external adjustment
It is possible to choose between internal and
external adjustment. The external adjustment
is active when the indicator is illuminated.
Anti-freeze
This machine is provided with an anti-freeze control.
The anti-freeze-control reduces the current when the
electrodes stick to the weld piece. This makes it easier
to break off the electrode and welding can continue.

MAINTENANCE

The machine requires periodical maintenance and
cleaning in order
cancellation of the guarantee.
WARNING !
Only trained and qualified staff members can
carry out maintenance
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.
