Stick Welding (MMA)
For starting welding process with MMA method you
should:
•
Insert welding cable plugs into output sockets and
twist to lock them in place.
•
Connect the work cable to the welding piece with
the work clamp.
•
Fasten a correct coated electrode into the electrode
holder.
•
Connect the main plug to the outlet mains socket.
•
Set the Local/Remote Switch in required position:
local or remote.
• Turn the Power on/off Switch on.
•
Set required welding current by knob of the Output
Current Control.
• Obeying appropriate rules you can begin to weld.

Electromagnetic Compatibility (EMC)

This machine has been designed in accordance with all relevant directives and standards. However, it may still generate
electromagnetic disturbances that can affect other systems like telecommunications (telephone, radio, and television) or
other safety systems. These disturbances can cause safety problems in the affected systems. Read and understand
this section to eliminate or reduce the amount of electromagnetic disturbance generated by this machine.
This machine has been designed to operate in an industrial area. To operate in a domestic area it is
necessary to observe particular precautions to eliminate possible electromagnetic disturbances. The
operator must install and operate this equipment as described in this manual. If any electromagnetic
disturbances are detected the operator must put in place corrective actions to eliminate these disturbances
with, if necessary, assistance from Lincoln Electric.
Before installing the machine, the operator must check the work area for any devices that may malfunction because of
electromagnetic disturbances. Consider the following.
• Input and output cables, control cables, and telephone cables that are in or adjacent to the work area and the
machine.
•
Radio and/or television transmitters and receivers. Computers or computer controlled equipment.
•
Safety and control equipment for industrial processes. Equipment for calibration and measurement.
•
Personal medical devices like pacemakers and hearing aids.
•
Check the electromagnetic immunity for equipment operating in or near the work area. The operator must be sure
that all equipment in the area is compatible. This may require additional protection measures.
•
The dimensions of the work area to consider will depend on the construction of the area and other activities that are
taking place.
Consider the following guidelines to reduce electromagnetic emissions from the machine.
• Connect the machine to the input supply according to this manual. If disturbances occur if may be necessary to take
additional precautions such as filtering the input supply.
•
The output cables should be kept as short as possible and should be positioned together. If possible connect the
work piece to ground in order to reduce the electromagnetic emissions. The operator must check that connecting
the work piece to ground does not cause problems or unsafe operating conditions for personnel and equipment.
•
Shielding of cables in the work area can reduce electromagnetic emissions. This may be necessary for special
applications.
WARNING
Maintenance or repairs
The frequency of the minatenance operations may vary
in accordance with the working environment where the
machine is placed.
Any noticeable damage should be reported immediately.
Routine maintenance (everyday)
•
Check cables and connections integrity. Replace, if
necessary.
•
Check condition and operation of the cooling fan.
Keep clean its airflow slots.
Periodic maintenance (every 200 working hours
but not more rarely than once a year)
Perform the routine maintenance and, in addition:
• Keep clean the machine. Using a dry ( and low
pressure) airflow, remove the dust from the external
case and from inside of the cabinet.
•
Check and tighten all screws.
Mains supply network must be disconnected from the
machine before each maintenance and service. After
each repair, perform proper tests to ensure safety.
