8. GETTING STARTED MMA
Getting started must be consistent with technical data and conditions of use.
1. Connect the electrode holder and the work lead to terminals
B13
and
B9
according the instructions on the electrode package.
NOTE
Prevent touching the electrode any metal material for in this
mode the terminals
B13
and
B9
are under current.
2. Press the button 19 to select the mode MMA
.
3. To select the current use the potentiometer 31.
4. It is possible to change the level of ARC FORCE by means of the
potentiometer
30.
9. ROUTINE MAINTENANCE & INSPECTION
1. The only routine maintenance required for the PEGAS range of machines is
a thorough cleaning and inspection, with the frequency depending on the
usage and the operating environment.
2.
WARNING
Disconnect the PEGAS from the mains supply voltage
before disassembling.
Special maintenance is not necessary for the control unit parts in the Welder.
If these parts are damaged for any reason, replacement is recommended.
3.
CAUTION
Do not blow air into the welder during cleaning. Blowing
air into the welder can cause metal particles to interfere with sensitive
electronic components and cause damage to the welder.
4. To clean the welder, disconnect it from the mains supply voltage then open
the enclosure and use a vacuum cleaner to remove any accumulated dirt and
dust. The welder should also be wiped clean. If necessary, solvents that are
