return to main display after several sec-
onds.
L18 ON selects material thickness. D2
shows thickness in mm for the welding pro-
cess.
Use E2 to change material thickness val-
ue. This value is stored in process memory.
Material thickness is a reference value
only, not a mandatory setting. D1 and D2

Pre−Gas is a similar function, but only
operates at the beginning of a welding
process. Purge can be performed in
the TIG process by pressing the torch
trigger without striking an arc.
