6. TORCH BUTTON MODE
We will now briefly describe the sequence used for welding in each process:
2t Lift-Arc Welding
Touch the piece being worked with the electrode of the torch.
Press (1T) and keep the button for the torch held down.
Slowly lift the torch to strike the arc.
The WELDING CURRENT goes to the value set, carrying out an ASCENT RAMP if necessary (adjustable time).
Release (2T) the button to start the process of completing the weld.
The current goes to the FINAL CURRENT value set in a period equal to the DESCENT RAMP time (adjustable).
The electric arc goes out.
The supply of gas continues for a period equal to the POST-GAS time (adjustable).
4t Lift-Arc Welding
Touch the piece being worked with the electrode of the torch.
Press (1T) and release (2T) the button of the torch.
Release the torch slowly to strike the arc.
The WELDING CURRENT goes to the value set, carrying out an ASCENT RAMP if necessary (adjustable time).
Press (3T) and keep the button held down to start the process of completing the weld.
The current goes to the FINAL CURRENT value set in a period equal to the chosen DESCENT RAMP time (adjustable).
The electric arc stays lit, and is supplied by a current equal to the FINAL CURRENT (adjustable).
Under these conditions, it is possible to carry out the closing of the weld bath (CRATER FILLER CURRENT).
Release (4T) the button to cut off the arc.
