5.3.5. Assembly and change of the feeding pulleys
The feeding pulleys must be adjusted to the diameter and composition of the wire
used for welding to ensure the optimal feeding of the wire electrode.
The pulleys for welding with a steel wire of diameter 0.6 to 1.2 mm are supplied with
the source.
The special “U” shape pulleys are necessary for welding aluminium (they are not
supplied). The change procedure:
put the power switch into the position “0“
lift off the side plate of the source
put the tension device forward – the pressure pulleys go up automatically
unscrew the plastic retaining parts of the feeding pulleys and remove the pulleys
put on the correct pulleys according to the used welding wire (value of the wire
diameter is stamped on the side of the pulley)
screw the plastic retaining parts
put down the pressure pulleys
tip over the tension device into a vertical position
5.3.6. Preparation of the source for welding, setting of the welding parameters
The source is prepared according to points 5.3.1. to 5.3.5
connect the ground welding cable into the plug “-13“ and connect to weldment
switch over the power switch of the source “20“ into the position “I“
check the position of the switch “9“ – “MIG/MAG“, the switch “14“- “2T“
press the button “5“
segment at
“m/min“
– setting of the feeding speed of the wire flashes on the
upper display “6”
set the required value of the wire feeding with the control element “8“
press the button “5“
segment at
“V“
– setting of the arc voltage flashes on the lower display “7”
set the required value of the voltage with the control element “8“
start welding
Thus the basic setting of the source for welding of MIG/MAG technology is finished.
Arc dynamic is finally adjusted by the control “10“
If further adjustment of the process parameters is necessary, it is made by repeating
the procedure according to point 5.3.6.
The source is supplied with other functions to enhance the useable qualities. These
will be described below.
