Figure 5 If the welding polarity has to be changed, user should: Switch off the machine. Determine the polarity for the electrode to be used
(or wire). Consult the data for this information. Select and set the correct polarity: positive or
negative. WARNING
Before welding check the polarity for using electrodes and wires.
WARNING The machine must be used with the door completely closed during welding.
WARNING Not use handle to move the machine during work.

Loading the Electrode Wire
Depending on the type of wire spool it can be installed on the wire spool support without adapter or installed with use applicable adapter that must be purchased separately (see “Accessories” chapter).
WARNING Turn the input power OFF at the welding power source before installation or changing a wire spool.
Turn the machine off. Open the side cover of the machine. Unscrew the locking nut of the sleeve. Load the spool with the wire on the sleeve such that
the spool turns anticlockwise when the wire is fed into the wire feeder. Make sure that the spool locating pin goes into the fitting hole on the spool. Screw in the fastening cap of the sleeve. Put on the wire roll using the correct groove corresponding to the wire diameter. Free the end of the wire and cut off the bent end making sure it has no burr. The device is adapted to the spool max. 300mm
WARNING Sharp end of the wire can hurt.
Rotate the wire spool anticlockwise and thread the end of the wire into the wire feeder as far as the Euro socket.
Adjust force of pressure roll of the wire feeder properly.
Adjustments of Brake Torque of Sleeve
To avoid spontaneous unrolling of the welding wire the sleeve is fitted with a brake. Adjustment is carried by rotation of its Allen screw M8, which is placed inside of the sleeve frame after unscrewing the fastening cap of the sleeve.

Adjusting of Force of Pressure Roll Force
The pressure arm controls the amount of force the drive rolls exert on the wire. Pressure force is adjusted by turning the adjustment nut clockwise to increase force, counterclockwise to decrease force. Proper adjustment of pressure arm gives the best welding performance.
WARNING If the roll pressure is too low the roll will slide on the wire. If the roll pressure is set too high the wire may be deformed, which will cause feeding problems in the welding gun. The pressure force should be set properly. Decrease the pressure force slowly until the wire just begins to slide on the drive roll and then increase the force slightly by turning of the adjustment nut by one turn.

Changing Driving Rolls
WARNING Turn the input power off of the welding power source before installation or changing drive rolls.
BesterMig 215-S is equipped with drive roll V0.8/V1.0 for steel wire. For others wire sizes, is available the proper drive rolls kit (see “Accessories” chapter) and follow instructions: Turn the input power OFF. Release the pressure roll lever [27]. Unscrew the fastening cap [29]. Change the drive roll [28] with the compatible ones
corresponding to the used wire.
WARNING Be sure that the gun liner and contact tip are also sized to match the selected wire size.
Screw fastening cap [29]. Manually feed the wire from the wire reel, the wire
through the guide tubes, over the roller and guide tube of Euro Socket into liner of gun. Lock the pressure roll lever [27].

Gas Connection
A gas cylinder must be installed with a proper flow regulator. Once a gas cylinder with a flow regulator has been securely installed, connect the gas hose from the output of the regulator to the machine gas inlet connector.
WARNING The welding machine supports all suitable shielding gases including carbon dioxide, argon and helium at a maximum pressure of 5,0 bars.
NOTE: When using the GTAW lift process, connect the gas hose from the GTAW torch to the gas regulator on the shield gas cylinder.
Transport and lifting
WARNING Falling equipment can cause injury and damage to unit.
Do not use handle to lift or support unit.

Maintenance
WARNING For any repair operations, modifications or maintenances, it is recommended to contact the nearest Technical Service Center or Lincoln Electric. 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 (everyday) 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 (every 200 working hours but at list once every year) 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.
The frequency of the maintenance operations may vary in accordance with the working environment where the machine is placed.
WARNING Do not touch electrically live parts.
WARNING Before the case of welding machine will be removed, the welding machine had to be turned off and the power lead had to be disconnected from mains socket.
WARNING Mains supply network must be disconnected from the machine before each maintenance and service. After each repair, perform proper tests to ensure safety.
