Loading Wire; Wire Liner Replacement - Prima MIG 210 SYNERGIC Operating Instructions Manual

7.0 LOADING WIRE

Your Mig welder is designed to accept either 5kg or 15kg wire spools of mild steel, stainless steel or aluminium according to the type of metal
you wish to weld. Wire spools aren't supplied with the unit and must be purchased separately.
Ensure the gas and electrical supplies are disconnected. Before proceeding,
remove the nozzle and the contact tip from the torch.
√
Open the side panel. Loosen the nut (A) of the spool holder (position 1) (brake drum).
Remove the spacer (E). In the case you are replacing the wire spool, extract it by
pushing the snap tongue (D) (Fig.9).
√
Remove the plastic protection from the spool. Place it on the spool holder. Mount
the spacer again (only for 5kg spools) and tighten the lock nut (A).
FIG. 10
√
Loosen and lower the plastic knob (A-FIG11). Release the upper roll (B-FIG11) of the feeder. Extract the wire from the torch liner.
√
When the wire is disconnected, grasp it with pliers so that it cannot exit from the spool. If necessary, straighten it before inserting it in the
wire input guide (C-FIG11). Insert the wire on the lower roll (D-FIG11) and in the torch liner (E-FIG11).
WARNING: keep the torch straight. When feeding a new wire through the liner, make sure the wire is cut cleanly (no burrs or angles) and
that at least 2cm from the end is straight (no curves). Failure to follow these instructions could cause damage to the liner.
√
Lower the upper roll (B-FIG11) and place the knob (A-FIG11). Tighten slightly. If tightened too much, the wire gets locked and could cause
motor damage. If not tighten enough, the rolls will not feed the wire.
When changing the wire diameter being used, or replacing the wire feed roll, be sure that the correct
groove for the wire diameter selected is inside, closest to the machine. The wire roll is driven by the
inside groove. Feed rolls are marked on the side identifying the groove nearest that side.
√
Close the side panel of the machine. Connect the power supply cable to the power output line. Turn
on the switch. Press the torch switch. The wire fed by the wire feeding motor at variable speed must
slide through the liner. When it exits from the torch neck, release the torch switch. Turn off the ma-
chine. Mount the contact tip and the nozzle.
When checking the correct exit of the wire from the torch do not bring your face near the
torch, you may run the risk to be wounded by the outgoing wire. Do not bring your fi ngers
close to the feeding mechanism when working! The rolls, when moving, may crush the fi n-
gers. Periodically, check the rolls. Replace them when they are worn and compromise the
regular feeding of the wire.

8.0 WIRE LINER REPLACEMENT

Before performing this procedure, ensure the gas and electrical
supplies are disconnected.
√
Disconnect the torch from the machine.
√
Place it on a fl at surface and carefully remove the brass nut (1).
√
Pull the liner (2) out of the hose.
√
Install the new liner and mount the brass nut (1) again.
Warning: the lenght of the new wire liner must be the same of the liner
you have just pulled out of the hose.
√
Connect the torch to the machine and install the wire into the feeding
system.
Your Mig welder can also accept 0,8kg wire spools by mounting a spacer (G) that
must be purchased separately . (Fig10)
For the mounting follow these instructions:
√
Remove the wire spool (B) from the spool holder (C).
√
Loosen the nut (A), remove the spring and the washer; remove the spool holder
(C) from the pivot.
√
Insert on the pivot the 0,8kg wire spool; Mount the washer, the spacer (G) and
the spring.
√
Tighten the lock nut (A).
Tighten nut to appropriate tightness. Excessive pressure strains the wire
feeding motor. Too little pressure does not allow the immediate stop of the
wire spool at the end of the welding.
