Weld Data Settings
The following is a summary of the welding parameters that affect the welding
process when using MIG welding methods.
With the power source in synergic mode it is only necessary to set the
wire feed
speed
.
The
voltage
parameter may also be adjusted if required.
When the wire feed speed is adjusted, the synergic control system automatically
adjusts certain other parameters to compensate. The parameters in italics remain
constant and are unaffected by changes in the wire feed speed.

Under the respective headings, are all settings that affect the start cycle and welding
stop.

There are three different functions that are designed to meet special requirements at
the start and end of the welding. These functions and auxiliary settings are made in
the start data menu and stop data menu.
