Welding SMAW (MMA) Process)
MAGPOWER 2100 i does not include the electrode holder with lead necessary for SMAW welding, but the one can be
purchased separately. See "Accessories" chapter.
Procedure of begin welding of SMAW process:
Determine the electrode polarity for the electrode to be used. Consult the electrode data for this information.
Depending on the polarity of using electrode, connect the work lead and the electrode holder with lead to output
socket or and lock them.

Connect the work lead to the welding piece with the work clamp.
Install the proper electrode in the electrode holder.
Turn the welding machine on.
Set the welding parameters.
The welding machine is now ready to weld.
By applying the principle of occupational health and safety at welding, welding can be begun.
User can set functions:
•

Maintenance
Warning: For any repair operations, modifications or maintenances, it is recommended to contact the
nearest Technical Service Center or Lincoln Electric Bester Sp. z o. o. Repairs and modifications
performed by unauthorized service or personnel will cause, that the manufacturer’s warranty will become
null and void.
Any noticeable damage should be reported immediately and repaired.
Routine maintenance
Check condition of insulation and connections of the work leads and insulation of power lead. If any insulation
damage exists replace the lead immediately.
Remove the spatters from the welding gun nozzle. Spatters could interfere with the shielding gas flow to the arc.
Check the welding gun condition: replace it, if necessary.
Check condition and operation of the cooling fan. Keep clean its airflow slots.
Periodic maintenance
Perform the routine maintenance and, in addition:
Keep the machine clean. Using a dry (and low pressure) airflow, remove the dust from the external case and from
the cabinet inside.
If it is required, clean and tighten all weld terminals.
