3.0 BRIEF INTRODUCTION

Your welder belongs to a range of welding
inverters for MMA - Manual Metal Arc Wel-
ding that adopts the latest pulse width mo-
dulation (PWM) techology and the insulated
gate bipolar transistor (IGBT) power module
to grant optimal performances: constant cur-
rent output to make welding arc more stable
and stepless current regulation. All inverters
are fi tted with automatic protection functions:
overvoltage, overcurrent and overtemperatu-
re.

4.0 INSTALLATION OF THE
EQUIPMENT
Proper operation of the generator is ensu-
red by adequate installation. The assem-
bly of the inverter must be done by expert
people, following the instructions and in
full respect of the safety standards.
- Remove the welder from the carton box.
BEFORE ATTEMPTING ANY ELECTRI-
CAL CONNECTION CHECK THE DATA
PLATE AND MAKE SURE THAT THE IN-
PUT VOLTAGE AND THE FREQUENCY
ARE THE SAME OF THE MAINS OUTLET
TO BE USED.
EARTHING
- To protect users the welding machi-
nes must be connected properly to the
- B
earth (ground) system (INTERNATIONAL
SAFETY REGULATIONS).
- It is indispensable to earth (ground)
2,7
the machine properly with the yellow-
60
green conductor of the power supply ca-
ble, in order to avoid discharges due to
accidental contacts with earthed objects.
- The chassis (that is conductive) is
electrically connected to the earth con-
H
ductor. Failure to earth the equipment
correctly can cause electric shocks dan-
gerous to the users.
- Plug the inverter to the mains.
4,2
Do not use the generator with input ca-
65
bles' extensions longer than 10m and
thinner than 2.5mm². Remember to keep
them layed and not wound or entangled.
Do not use the welder with the side panels
partially or completely removed in order
to avoid accidental contacts with inner
live parts.
- The inverter is now ready for use. Make
sure you are welding in a properly ventilated
area and that the ventilation openings of the
machine are not obstructed (poor air ventila-
tion may reduce the duty cycle of the unit and
cause damages). Now you may choose the
welding process by connecting the accesso-
ries as showed in the following pages.
