Spotmatic - EWM Tetrix 352 AC/DC Synergic Operating Instructions Manual

The up-slope and down-slope times should be set to "0" to achieve an effective result.
Example display with factory settings of the parameters:
Sequence:
• Press and hold torch trigger 1.
• The gas pre-flow time elapses.
• HF ignition pulses jump from the electrode to the workpiece, the arc ignites.
• The welding current flows and immediately assumes the value set for the start current
• HF is switched off.
• The welding current increases in the adjusted up-slope time to the main current
The process ends when the set spotArc.time elapses or by releasing the torch trigger.
When switching on the spotArc function, Automatic pulsing is switched on as well. Any other
pulsing variant can be selected as well, or no pulsing at all.

spotmatic

In contrast to the spotArc operating mode, the arc is not started by pressing the torch trigger as in the
conventional method, but by briefly placing the tungsten electrode
ger is used to enable the welding process. The activation is indicated by flashing of the spotArc®/spotma-
tic signal light. The separate process activation
are activated by default with spotmatic.
The following parameter settings can be adjusted in the machine configuration menu > see 5.9 chapter:
• Separate process activation (
The welding process must be re-enabled before each arc striking by tapping the torch trigger. Process
activation is automatically terminated after 30 s of inactivity.
• Permanent process activation (
The welding process is enabled by tapping the torch trigger once. The following arc striking processes
are initiated by briefly placing the tungsten electrode on the workpiece. Process activation is termina-
ted either by tapping the torch trigger again or automatically after 30 s of inactivity.
• Process start by placing the tungsten electrode on the workpiece (
• Process start by tapping the torch trigger (
• Short setting range of spot time (
• Long setting range of spot time (
In this case, the procedure is the same as for spotArc.
The time range setting is made in the machine configuration menu using the parameter
