Difference in the wire feed speed
The graphs for 15 m/min and 20 m/min relate to primary wire feed speed. The cycle time is
the sum of primary and secondary phase time.
The difference between primary and secondary wire feed speed may not exceed the speed
that is specified by the graphs for primary wire speed.
Example: If the cycle time is 0.25 s and the primary wire feed speed is 15 m/min, the
difference between primary and secondary wire feed speed may not exceed 6 m/min.
Weld example A
In this example we will weld a
10 mm plate
with
1.2 mm aluminium wire
and
argon
shielding gas
.
Make the following settings using the control panel:

11.0 m/min
0.1 s
Primary and secondary phase time are 0.1 s + 0.1 s
= 0.2 s
.
The difference in wire feed speed is 15.0 m/min - 11.0 m/min
= 4 m/min
.
