Duty Cycle And Overheating; Output Connections; Controls And Operational Features - Lincoln Electric SAF-RPO PRESTOMIG 185MP Manual De Instrucciones


Dirt and dust that can be drawn into the machine
should be kept to a minimum.

This machine has a protection rating of IP23. Keep it
dry when possible and do not place it on wet ground
or in puddles.

Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility in
this manual.

Do not operate in areas with an ambient temperature
greater than 40°C.

Duty cycle and Overheating

The duty cycle of a welding machine is the percentage of
time in a 10 minute cycle at which the welder can
operate the machine at rated welding current.
Example: 60% duty cycle
Welding for 6 minutes.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.
The machine is protected from overheating by a
temperature sensor.
Input Supply Connection
WARNING
Only a qualified electrician can connect the welding
machine to the supply network. Installation had to be
made in accordance with the appropriate National
Electrical Code and local regulations.
Check the input voltage, phase and frequency supplied
to this machine before turning it on. Verify the
connection of ground wires from the machine to the input
source. The welding machine PRESTOMIG 185MP,
PRESTOMIG 210MP must be connected to a correctly
installed plug-in socket with an earth pin.
Input voltage is 230V, 50/60Hz. For more information
about input supply refer to the technical specification
section of this manual and to the rating plate of the
machine.
Make sure that the amount of mains power available
from the input supply is adequate for normal operation of
the machine. The necessary delayed fuse (or circuit
breaker with "B" characteristic) and cable sizes are
indicated in the technical specification section of this
manual.
WARNING
The welding machine can be supplied from a power
generator of output power at least 30% larger than input
power of the welding machine.
WARNING
English
Break for 4 minutes.
When powering welder from a generator be sure to turn
off welder first, before generator is shut down, in order to
prevent damage to welder!

Output Connections

Controls and Operational Features

1. LED Indicator Power switch (only
PRESTOMIG 185MP): This LED lights
up when the welding machine is ON
and is ready to work
2. Thermal Overload Indicator: It indicates that the
machine is overloaded or that the cooling is not
sufficient. Depending on:
PRESTOMIG 185MP: Overload or
insufficient is shown by lighting LED
under the symbol.
PRESTOMIG 210MP: The message
as image is shown by the display
[13].
3. Process Welding's Switch:
GMAW (MIG/MAG) process
Warning: Can be used to FCAW-
SS process.
SMAW (MMA) process
When the machine is switched again on, last welding
process will be recalled.
