[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 ignition needs a physical contact between the
electrode and the work piece.
[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".
[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 parameter selection easier, and in some cases allows
transferring settings from one welding machine to another.
[MicroTack function]
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 Minilog current. Parameters
are preset by the user. Welding over tack welds is one application, and it also functions as a "pause current" when the welding pos-
ition changes for example.
[MIX TIG]
TIG welding function, where AC TIG and DC TIG processes alternate in predefined manner. Parameters are preset by the user accord-
ing to welding application. Used especially for optimizing welding of aluminum materials 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.
[Post gas]
Welding function that continues the shielding gas flow after the arc has extinguished. This ensures that the hot weld does not come
into contact with air after the arc is extinguished, protecting the weld and also the electrode. Used for all metals. Especially stainless
steel and titanium require longer post gas times.
[Pre gas]
Welding function that starts the shielding gas flow before the arc ignites. This ensures that the metal does not come into contact
with air at the start of the weld. Time value is preset by the user. Used for all metals, but especially for stainless steel, aluminum and
titanium.
[Pulse TIG]
TIG welding process, where the welding current changes between two current levels: base current and pulse current. Parameters can
be set either manually or automatically. Used for optimizing the arc characteristics for desired welding applications.
