Automatic Functions

Function

Description, Details

Creep automatic

Without active arc, the control unit reduces wire speed 

until wire end touches material. With touch, ignition 

starts automatically.  After ignition, the automatic system 

accelerates the wire speed to setpoint.

Wire speed automatic

The synergic control unit calculates wire speed based on 

the welding power set by the rotary switches 11, 12. 

Fine adjustment is done with regulator 6.

Burn back  

automatic / 

 

Free burn 

automatic

Intense of this automatic function is to prevent wire 

sticks to material when welding is stopped.

 

The welding control unit calculates the time required to 

avoid the wire sticking in relation to the actual wire 

speed and braking phase. 

Gas post-flow time

The default value is 0,2 sec after releasing torch trigger 

button.

Thread in automatic

With press and hold torch button in 2 step mode, the 

automatic phase to thread the wire startes if system 

detects no arc after 3 sec. 

 

Speed is set with regulator 6.

Welding stop automatic The output voltage is automatically switched off in 4 step 

mode if there is no current for 3 seconds.

Data hold automatic

After welding stop, the last current is stored and shown 

in 7 segment display 2 (data hold). 

SDI automatic

 

Steplessly controllable choke. 

Active if regulator 10 is in stop position on the left side.

Water cooling

All products with extension W are water cooled. 

The cooling starts automatically with the welding and 

stops with a delay time after welding stop.

Gas flow test

With the torch button pressed and without an arc for 3 

seconds, the gas valve opens automatically for maximum 

25 seconds. It stops when the button is released.
