Fronius TransTig 2600 Operating Instructions/Spare Parts List

5
Important!
- It is only possible to lower the current without interrupting the
welding sequence if "Main current" is activated
- If you accidentally push forward the torch trigger in in open
circuit, no ignition will take place
Special-4-step mode - Variant I (Fig.5)
- Makes it possible to activate the 4-step mode from TIG
torches that do not have the double-pushbutton function
- Intermediate lowering down to the reduced current I
3
(to set
this, see the section headed "Working with the program-
levels")
- Facility for lowering the welding current from the main
current to the reduced current I
3
and back, without inter-
rupting the welding sequence
- In the "PRESETTINGS LEVEL ---" program level (see "Wor-
king with the program-levels"), Parameter I3, the reduced
current I
3
can be set as a percentage of the main current I
H
- In the "PRESETTINGS LEVEL ---" program-level (see "Wor-
king with the program-levels"), parameter TIG, the setting
for SFS must be set to "1"
Special 4-step mode - Variants II / III / IV / V (Figs.5a/b/c/d)
- Makes it possible to activate the 4-step mode from TIG
torches with the double-pushbutton function
- In the "PRESETTINGS LEVEL ---" program-level (see "Wor-
king with the program-levels"), parameter TIG, the setting
for SFS must be set to
- "2" for Variant 2
- "3" for Variant 3
- "4" for Variant 4
- "5" for Variant 5
