Blinking of the H11 signal lamp followed by the error codes Err 8 and Err 9 is stopped by the
following start, if the reason of the error code has been abolished or if the gun has cooled down
or the motor is no more overloaded.
2.4. MOUNTING AND LOCKING OF WIRE REEL
– Release locking nails of wire reel hub by turning locking knob a quarter round.
– Mount the reel at its place. Note rotating direction of reel!
– Lock the reel with locking knob, locking nails of hub remain to outside position and will
lock the reel.
LOCKED OPEN
Check that in filler wire reel there are no parts sticking out, which could e.g.
chafe against chassis or door of wire feed unit. Dragging parts might expose
chassis of wire feed unit under voltage.
2.5. AUTOMATIC WIRE FEED TO GUN
Automatic wire feed in PROMIG wire feed units makes change of wire reel more rapid. In
reel change the pressure of feed rolls need not to be released and filler wire goes automatically
to correct wire line.
– Make sure that groove of feed roll match the diameter of welding wire used. Feed roll groove
is selected by moving the groove selecting washer (28).
– Release the wire end from reel and cut off the bent length. Be careful that the wire does
not spill from the reel to sides!
– Straighten about 20 cm of the wire and see that the end of it has no sharp edges (file off if
necessary). A sharp edge may damage the wire guide tube and contact tip of the welding gun.
Promig 501:
– Draw a bit of loose wire from wire reel. Feed wire through back liner to feed rolls. Don’t
release pressure of feed rolls!
– Press the gun switch and feed a bit wire until wire goes through feed rolls to gun. See that
wire is in grooves of both feed roll pairs!
– Press still the gun switch until wire has come through contact tip.
Automatic feed may sometimes fail with thin wires (Fe, Fc, Ss: 0,6...0,8 mm, Al: 0,8...1,0 mm).
Then it might be possible that you must open feed rolls and feed wire manually through feed
rolls.
Promig 511:
– Feed wire through wire cone and further until feed rolls. Don’t release pressure of feed rolls!
– Press the gun switch and feed a bit wire until wire goes through feed rolls to gun. See that
wire is in grooves of both feed roll pairs!
– Press still the gun switch until wire has come through contact tip.
