7. Mounting of Promig 501 to boom
Wire feed unit must be mounted to boom in such a way that its chassis is galvanic
separated both from swing arm and boom.
Suspension angle of wire feed unit can be changed by moving fixing point in handle.
2.2. ACCESSORIES 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:
Universal feed roll for welding of all kinds of wires.
Feed rolls with knurled groove: Special feed roll for cored wires and steel wires.
Feed rolls with U groove: Special feed roll for aluminium wires.
Trapezoid slotted , pivoted feed wheels: For heavy welding
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
colour filler wire ø mm (inch)
white 0.6 ja 0.8 (0.030)
red 0.9/1.0 ja 1.2 (0.035, 0.045 and 0.052)
yellow 1.4, 1.6 ja 2.0 (1/16 and 5/64)
black 2.4 (3/32)
guide tubes
colour filler wire ø mm (inch)
orange 0.6-1.6 (0.024-1/16)
blue over 1.6 (over 1/16)
In delivery Promig 501 and 511 are equipped with red feed rolls with plain groove and with
orange wire guide tubes for welding filler wires of 0.9-1.2 mm (0.035”, 0.045” and 0.052”).
2.3. MOUNTING OF MIG WELDING GUN
In order to ensure trouble-free welding check in operation instructions of gun used by you that
wire guide tube and contact tip of gun are according to manufacturer’s recommendation suitable
to be used for wire feed diameter and type in question. Too tight a wire guide tube might cause
for wire feed unit a bigger stress than normally as well as disturbances in wire feed.
Screw snap connector of gun tight that there won’t come any voltage losses on connecting
surface.
A loose connection will heat gun and wire feed unit.
When you are using liquid-cooled gun, mount water hoses according to figure on page 7.
Error signal lamp H11 of Promig 501 and 511 units have operations for overheating of liquid-
cooled PMT or WS gun and for overload of wire feed motor. Operation of signal lamp is as
follows (also see error codes on page 30):
1. Thermal release of the KEMPPI PMT or WS gun is operating. Then the equipment stops the
welding, yellow signal lamp H11 starts to blink and at the same time on (wire feed) display
of panel appears the text Err 8.
2. The wire feed motor is slightly overloaded e.g. due to a blocked gun. Then the error signal
lamp H11 starts to blink. If overload of motor is big, welding is stopped and on (wire feed)
display of panel appears the text Err 9.
