Tig Antistick; Welding Torch (Operating Variants); Tapping Function (Tap Torch Trigger); Torch Mode Setting - EWM T4.07 Operating Instructions Manual

Functional characteristics
TIG welding
5.1.6

TIG antistick

The function prevents uncontrolled re-ignition following the sticking of the tungsten electrode in the weld
pool by switching off the welding current. In addition, wear at the tungsten electrode is reduced.
After triggering the function the machine immediately switches to the gas post-flow process phase. The
welder starts the new process again at the first cycle. The user can switch the function on or off (parame-
ter ) > see 5.6 chapter.
5.1.7

Welding torch (operating variants)

Different torch versions can be used with this machine.
Functions on the operating elements, such as torch triggers (BRT), rockers or potentiometers, can be
modified individually via torch modes.

Tapping function (tap torch trigger)

Tapping function: Swiftly tap the torch trigger to change the function. The set torch mode determines the
operating mode.
5.1.7.2

Torch mode setting

Modes 1 to 4 and 11 to 14 are available to the user. Modes 11 to 14 feature the same functionality as 1 to
4, but without the tapping function > see 5.1.7.1 chapter for the secondary current.
The functionality of the individual modes can be found in the corresponding torch type tables.
The torch modes are set using the torch configuration parameters "
menu > torch mode "
Only the modes listed are suitable for the corresponding torch types.
5.1.7.3

Up/down speed

Functionality
Press and hold the up push-button:
Increase current up to the maximum value (main current) set in the power source.
Press and hold the down push-button:
Decrease current to the minimum value.
Use the machine configuration menu > see 5.6 chapter to set the up/down speed parameter
determines the speed with which a current change becomes effective.
5.1.7.4

Current jump

By tapping the corresponding torch trigger the welding current can be determined in an adjustable jump
range. Each tap will cause the welding current to jump up or down by the defined value.
The "current jump" parameter
