I
Ignition current
Adjusts the current level of the negative ignition sequence (TIG).
Ignition mode
The way in which the welding arc is ignited. In TIG welding, two ignition modes are available: High Frequency
(HF) ignition and Lift TIG ignition. The HF ignition uses a voltage pulse to initiate the arc, and the Lift TIG igni-
tion needs a physical contact between the electrode and the work piece.
L
Lift TIG current
Contact current in the beginning of Lift TIG ignition.
Lift TIG ignition
Ignition mode in TIG welding. In Lift TIG ignition you briefly touch the work piece with the electrode, then
press the trigger and lift the electrode to a small distance from the work piece. The Lift TIG ignition must be
activated in the control panel. Also known as "Touch ignition" or "Contact ignition".
M
Manual pulse
TIG welding process, where the welding current alternates between two current levels: base current and pulse
current. Parameters are preset by the user. Used for optimizing the arc characteristics for desired welding
applications.
Memory channel
Place to store predefined welding parameter settings. A welding machine can include a number of preset
channels. Users can create new channels for their own welding jobs and modify or delete them. Makes para-
meter selection easier, and in some cases allows transferring settings from one welding machine to another.
MicroTack
TIG welding function, which optimizes the spot welding characteristics. Used for tack welding of thin sheets or
materials of different thicknesses. Allows fast and easy creation of clean tack welds with minimum heat input.
Minilog
TIG welding function, which allows using the torch switch to change between the welding current and Mini-
log current. Parameters are preset by the user. Welding over tack welds is one application, and it also func-
tions as a "pause current" when the welding position changes for example.
MIX TIG
TIG welding function, where AC TIG and DC TIG processes alternate in predefined manner. Parameters are pre-
set by the user according to welding application. Used especially for optimizing welding of aluminum mater-
ials of dissimilar thicknesses.
MMA
Manual arc welding process that uses a consumable electrode. The electrode is covered with flux material that
protects the weld area from oxidation and contamination.
