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 weld-
ing 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.
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.
MMA antifreeze
A function which automatically decreases the welding current significantly when electrode is touching the
workpiece. Can be used for avoiding MMA electrode getting too hot when it's in contact with the work-
piece.
P
Pulse current
The higher current level of the pulse cycle. In TIG welding, its main task is to create weld pool or increase
the heat of the weld pool.
Pulse frequency
Determines how many pulse cycles is created per second (Hz).
Pulse ratio
Determines how big part of the whole pulse cycle time is spent on pulse current.
S
Slight upslope
This is a function that automatically creates a slight upslope to prevent electrode wearing caused by sud-
den current rises with high welding currents. This function has an effect only when the welding current is
100 A or more.
Startup level
The point of welding current where the upslope begins.
T
TIG
Manual welding process that typically uses a non-consumable tungsten electrode, a separate filler mater-
ial, and an inert shielding gas to protect the weld area from oxidation and contamination during the weld-
ing process. The use of a filler material is not always mandatory in TIG welding.
