2.2. INSTALLATION OF MIG SYSTEM
2.2.1. Equipment corresponding to wire diameter
Promig wire feed rolls are available with plain groove, knurled groove and with U groove for
different purposes.
Feed rolls with plain groove: General feed roll for all kinds of wires.
Feed rolls with knurled groove: Special feed roll for cored wires and steel wires.
Feed rolls with U groove:
Special roll for aluminium wires.
Promig wire feed rolls have two grooves for different filler wire diameters. Correct wire groove
is selected by moving selecting washer (28) from one side to another in feed roll.
Feed rolls and wire guide tubes of wire feed unit have colour codes in order to make identifica-
tion easier.
Feed rolls:
white for 0,6... 0,8 mm fillerwires
red for 0,9 ... 1,32 mm fillerwires
yellow for 1,4... 2,0 mm fillerwires
Wire guide tubes: orange for 0,6... 1,6 mm fillerwires
blue for over 1,6 mm fillerwires
In delivery the Promig 100 is equipped with red feed rolls with plain groove and with orange
wire guide tubes for welding filler wires of 0,9...1,32 mm.
2.2.2. Mounting of intermediate cable and wire liner
The intermediate cable is connected with the EURO adaptor to the Promig 501, 501L and
530 wire feeder. Remote control and synchronizing connectors of the intermediate cable are
connected to the corresponding connectors in the feeder unit.
The tip of the intermediate cable on the sub-feeder side is pushed into the opening at the
rear of the Promig 100. The EURO adaptor is fastened carefully and the control/synchronizing
connector is pressed down on its place.
The cooling liquid hoses are placed into room reserved for them according to enclosed figure.
See in mounting of connectors that they really are fast, especially the EURO adaptors should be
tightened tightly enough that no voltage losses or sparking wouldn’t come up in connectors.
When you are fastening the intermediate cable to the sub-feeder, loosen the fastening screw 31
(see figure) of the wire guide tube in order to ensure the electric contact. A bad connection is
heated up in welding and connecting parts may even be destroyed.
Wire liner
Length Symbol colour Order number
Steel spiral 15 m yellow 4188594
25 m yellow 4188596
Plastic 15 m black 4271020

Wire liner of the intermediate cable is either of steel spiral or plastic. The plastic wire liner
is always used in welding of aluminium or stainless steel. The steel spiral is used in welding
of cored wire. In welding of solid steel wire you can use as wire liner both the steel spiral
and the plastic wire liner.
