150
Adjustable rod
electrode param-
eters
End-delay
Delay in the start of wirefeeding from end of the main current phase
Unit s
Setting range OFF / 0.1 - 9.9
Wire wdraw
Unit mm in.
Setting range OFF / 1 - 50 OFF / 0.04 - 1.97
IMPORTANT! Wire withdrawal prevents the welding wire from burning at the end. Before
the welding current is switched off, the wire is withdrawn to the set value. A prerequisite
for this function is that the arc has ignited.
Wire threading
Wire threading speed
Unit m/min ipm.
Setting range 0.1 - max. 3.94 - max.
Main current
Unit A
Setting range MW 2500 Comfort 3 - 250
MW 3000 Comfort 3 - 300 TT 2500 Comfort 3 - 250
TT 3000 Comfort 3 - 300
Arc-force dynamic
In order to obtain optimum welding results, it will sometimes be necessary to set the arc-
force dynamic function.
Unit % (of main current)
Setting range 0 - 100
0 soft, low-spatter arc
100 harder, more stable arc
Functional principle:
at the instant of droplet transfer or when a short circuit occurs, there is a momentary rise
in amperage. In order to obtain a stable arc, the welding current is temporarily increased.
If the rod electrode threatens to sink into the weld pool, this measure prevents the weld
pool solidifying, as well as preventing more prolonged short circuiting of the arc. This
largely prevents the rod electrode from sticking.
Jobslope
For changing to another job during welding. Jobslope is the time that it takes for the weld-
ing current to adjust seamlessly from the present job to the next.
Unit s
Setting range Off / 0.1 - 9.9
NOTE! Switching over from one job to the next without interrupting welding is only
possible with a JobMaster TIG welding torch, robot interface or field bus.
Starting current
Unit % (of main current)
Setting range 30 - 200 AC, 0 - 200 DC
