Feed rolls and wire guide tubes of wire feed unit have colour codes in order to make identifica-
tion easier (see table on page 7).
In delivery Promig 200 and 300 are equipped with red feed rolls with orange wire guide tubes
for welding filler wires of 0
2.2.2. Mounting of MIG welding gun
In order to ensure trouble-free welding check the operation instructions of the gun used, that
the wire guide tube and contact tip are suitable for the wire diameter and type you are using.
Too tight a wire guide tube might cause for wire feed unit a bigger stress than normally as well
as disturbances in wire feed.
Ensure that the screw nut of the snap conector on the gun is done up tightly when fitted to
the Promig feeder so that there will not be any voltage losses through the snap connector. A
loose connection will heat gun and wire feed unit. When you are using liquid-cooled gun, mount
cooling liquid hoses according to fig. on pages 5, 6.
Error signal lamp H11 of Promig 200 and 300 units have operations for overheating of liquid-
cooled MIG gun and for overload of wire feed motor. By operation of the signal lamp its so-
called short flashes indicate the error code in question (also see operation of error signal lamp,
page 16):
8 short flashes Err 8:
Liquid-cooled gun MIG is overheated.
9 short flashes Err 9:
Overload of wire feed motor, which can come from blocked wire
liner of gun.
Blinking of H11 lamp which follows error codes Err 8 and Err 9 ends by following start, if
the fact which caused the error code has been eliminated, or if the gun has cooled down or the
motor is no more overheated.
2.2.3. Mounting and locking of wire reel
- Release locking tongues of wire reel hub by turning locking knob a quater of a turn.
- Mount the reel at its place.
Note rotating direction of reel!
- Lock the reel with locking knob, locking tongues of hub remain to outside position and will
lock the reel.
Check that in filler wire reel there are no parts sticking out, which could e.g.
scrub against chassis or door of wire feed unit. Dragging parts might expose
chassis of wire feed unit under voltage.
2.2.4. Automatic wire feed to gun
When changing the wire reel the pressure of the feed rolls need not be released as the filler wire
will automatically feed into the 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).
