WELDING PROCEDURES
Evo multi4 is the new panel for engine driven welders by
MOSA, created with the purpouse of giving to the user a
complete new experience in which it is possible to control each
parameter of the welding:
- Voltage control
- Curren control
- Arc force setting
- Starting voltage
- Slope of the starting/stop current
- Switching frequency for pulsed Tig.
NEW POSSIBILITIES
EVO multi4 exploits the power of a 32 bits microcontroller to
get every welding signals to control them. There are 6 different
kinds of welding procedures, each with 3 different proles, in
this way the machine has 18 welding programs. The user can
use and modify the programs in order to make the machine
completely personalized according to user needs.
Display allows the user not just to see voltage and current
during the welding process but also to set these parameters
before starting the process.
The electronic board use the CAN protocol to communicate
with other boards in case of dual station machine, furthermore
it has a real-time clock to generate log les.

STICK
Stick welding uses an electrode as tool for welding. In this
mode it is possible moving the LEFT encoder setting the
CURRENT.
The RIGHT encoder changes the ARC FORCE strenght, with
this parameter it is possible to control the heat of the welding.
During the welding procedure, left display shows the
current while the right one shows the voltage. Moving
the right encoder will show again the arc force
percentage on the right display.
Secondary parameters
It is possible to change, for each type of welding procedure,
secondary parameters that have soft impact on the welding,
for stick procedure this parameters are:
- VRD on/off
- HOT START % current
- HOT START time.
VRD on/off
VRD (Voltage redution device) is used to reduce the voltage
at values lower than 13V, when the machine is not working.
This is useful when the environment is humid. It is possible to
deactivate it using the software of the panel.
HOT START % current
It is possible to set the HOT START, in this way it is easier to
start the welding process. The start-up current is higher than
the nominal for a small period. The range is between 15A and
30A, if this parameter is set to 0% the function is deactivated.
HOT START time
Changing this parameter will affect the duration of the HOT
START, so the time during which the current will be higher
than the nominal one. This parameter may vary between 0.5s
and 3s.
