TIP: Crater filling stops when the trigger switch is released. Keeping the button pressed
continues welding at the lower data of the crater filling function (dotted line).
- Activation of 4-stroke performed in the MAIN MENU.
Crater filling
Crater filling helps to avoid pores, thermal cracking and crater formation in the workpiece at
the end of the weld.
- Setting of crater filling time performed in the SETTINGS MENU.
Hot start
The hot start function increases the welding current for an adjustable time at the start of
welding, which reduces the risk of poor fusion at the start of the weld.
- Setting of hot start time performed in the SETTINGS MENU.
Creep start
Creep start function feeds out the wire at 1.5 meters/minute until it makes electrical contact
with the workpiece.
- Activation of creep start performed in the MAIN MENU.
Gas purging
The gas purging function is used when measuring the gas flow rate, or to purge the gas
hoses of any air or moisture before starting to weld. It continues as long as the button is held
pressed, and prevents voltage from being applied and wire feed from starting.
- Activation of gas purging performed in the MAIN MENU.
Cold wire feed (Wire inching)
Cold wire feed is used in order to feed out wire without energising the arc. The wire is fed out
for as long as the button is held pressed.
- Activation of cold wire feed performed in the MAIN MENU.
QSet™
QSet™ function is used to facilitate setting welding parameters.
NOTE!
QSet™ function and Synergy function are mutually exclusive. If one is selected, the
other will be deselected. Both can be OFF.
• Turning the knob clockwise increases (+) the
arc length.
• Turning the knob anti-clockwise reduces (-)
the arc length.
SHORT ARC
When first starting welding with a wire type / gas type QSet™ automatically sets all the
necessary welding parameters. After that QSet™ stores all the data to produce a good weld.
The voltage then automatically conforms to changes in the wire feed speed.
SPRAY ARC
When approaching the spray arc area the value for QSet™ must be increased. Disengage
the QSet™ function when welding with pure spray arc. All settings are inherited from QSet™,
with the exception of the voltage which must be set.
