At the end of the weld, a peak of current is used cut the wire and to ensure a clean re-arc. This peak of
current can be a problem on thin metal, in this case the « burn-back » option can be selected to finish
the wire with a more traditional 'ball' and will limit the energy supplied at the end of the weld in order
to preserve the welding bead.
PLS & PIP mode
The icon
allows you to enter the welding process menu and modify the settings of each stage (pre-gas, hot-start,
Upslope, downslope, burn-back, post-gas). This menu is only available with the PRO interface. (see « setup menu», last
page).
Pulse (PLS)
PULSEMIG 300-T2
The icon
allows you to enter the welding process menu and
modify the settings of each stage (pre-gas, hot-start, Upslope, downs-
lope, burn-back, post-gas). This menu is only available in PRO mode.
In the secondary menu of PRO mode, the settings can be locked
unlocked
by the operator in order to be used in EASY mode without
modifying the settings.
To modify the code. (Unlocking code: 0000)
The language selection can be modified or reset
: Reset the system (to factory settings)
: Synergic update
: Card and software details
: Indicate the state of the external water cooling system.
The icon
allows you to save or load the saved settings.
There are 3 ways to adjust the welding parameters:
- wire speed:
- metal thickness:
- welding current :
: shows the theoretical welding current
: allows adjustment of the arc length
: The smoothing coil enables the arc strength to be adjusted by
modifying the pulse on standard welding or the pulse frequency on
pulsed welding.
GAS PRE-FLOW : pre-gas time before welding.
CREEP_SPEED : reducing coefficient of the approach speed (Reduce for thick sheets, e.g. 50% .
Do not change for thin metal sheets, e.g. : 100%).
Overcurrent, useful with aluminium (eases the arc strike) to preheat the metal piece (> 100%)
or useful with steel during the approach phase (< 100%), can also improve the arc's ignition.
T Hot start : preheating phase time in 2T mode. For the 4T mode, enter another value than 0 to
activate it.
Delta U Hotstart : acts on the arc length during preheating phase.
Upslope time.
Delta U Upslope : acts on the arc length during upslope phase.
Downslope : downslope time.
Delta U Downslope : acts on the arc length during downslope.
I Crater Filler : only active in 4T, can set the current level to prevent pinholes at the end of the
weld.
Delta U Crater filler : acts on the arc length during pinhole filling phase.
Post gas flow duration.
