* DYNAMICS – Turn ON or OFF by turning left (OFF) or right (ON) the parameters adjustment turning button at the
end of the TIG cycle parameters. Not available in PULSE mode.
TIG HF / LIFTIG Pulsed welding - the welding current varies between a high current value and a low current value
to reduce the heat input on the thinnest plates and to better control the arc.

- Start welding.
NOTE: Please refer to chapter A - Appendix, where the tables are presented with the parameter values that can be
adjusted per welding process for the TP 254 DC, TP 324 DC, TP 404 DC and TP 504 DC.
Fig. 4 – TIG parameters
Parameter
I
Welding current or, in pulsed mode, peak current
p
UP SLOPE
Up slope time in seconds from IStart to welding current (Ip)
I Start
Initial welding current (Amp)
Pre Gas
Pre-gas time in seconds - interval between gas flow and arc
ignition. Allows starting welding within inert gas atmosphere.
DOWN
Down slope time from welding current to final current for crater
SLOPE
filler
I Final
Final current for crater filler.
POST GAS
Post-gas time - interval after arc extinction to maintain gas
protection at the end of welding. Prevents welding pool and
tungsten electrode oxidation.
DYNAMICS
arc length compensation. Useful for unexperienced welders.*
tSPOT
Set the stitch time (valid for SPOT mode)
Parameter
Ib
Base current indicator
WIDTH
Adjust width of the peak current (main)
PULSE
Adjust the pulse frequency.
