4. SERVICE INSTRUCTIONS
4.1. Programming
MinarcTig Evo 200 has a microprocessor on the P001 card. It can be reprogrammed using Datamaster 2
(DM2 later in this document) service device. Panel card has 10-pin connector X10 where DM2 flat cable
can be connected.
Both normal MinarcTig and MLP versions use the same software. First software must be uploaded to the
DM2 using Datamaster 2 PC software, which is provided on a CD included with the DM2. Once the soft-
ware is installed on the PC, it can then be transferred to the DM2 via a USB cable. Now the DM2 is ready
to be used for MinarcTig update.
Open the MinarcTig case and connect the 10-pin connector to panel X10. Switch on the MinarcTig and
start updating and wait until downloading is completed. Once it is finished, DM2 can be disconnected and
the new software is ready to be used. Software version can be checked by switching on the machine and
then pressing one of the panel buttons. 7-Segment display shows the software version.
See more DM2 information in the user manual.
4.2. Measurements and tests
4.2.1. Z001 Main circuit card
Power stage is divided in to two parts: rectifier/PFC module and IGBT module. They can be tested sepa-
rately by using simply digital multimeter.
4.2.1.1. Input rectifier and PFC circuit
Main supply voltage must not be connected during the rectifier/PFC module diode measuring.
In many case of primary side failures input rectifier or the PFC circuit diodes may get defective. Rectifier
and PFC diodes can be measured one at a time. PFC has one diode in series with IGBT and one dis-
charge diode.
