MIG welding dynamics adjustment
With MIG welding dynamics adjustment is influenced on welding stability and spatter amount.
Zero setting is recommended basic setting. Values –> min (-1...-9), softer arc for reduced
spatter amount. Values –> max (1...9), harder arc for increased stability and when 100 %

shielding gas is used in welding of steel.
Selecting switch of main controls
Remote control, basic controls are made from C 110D remote control unit, which is con-
nected to the FEED 400.
Gun control, wire feed speed or welding current (1-knob MIG) control is made from the
RMT10 control unit, which is mounted to the PMT MIG gun. Control of welding voltage or
arc length is made from the voltage control potentiometer of the panel.
Local control, basic controls are made from potentiometers of the panel.
Display of selected 1-knob MIG synergic program
The display shows number for 1-knob MIG program, which has been selected with select-
ing switches on the synergy panel. If on display is visible ´ – –´ , you have not selected any 1-
knob MIG program. Then welding is prevented. By normal MIG / MAG welding the display is
dark.

Burn back time adjustment
The burn back time is adjusted steplessly. The value for burn back time is selected according to material in question
so that the filler wire won´t stick on the weld piece at the weld end, and also that there won´t be produced too big "ball"
at the wire tip. The burn back time is changed automatically right according to changes of the wire feed speed.
Selection of 1-knob MIG synergic curve
The FEED 400 includes preset programs for synergic 1-knob MIG welding of the most common materials. The
preset programs are presented in the enclosed table. On reel cabinet door of the Feed 400 there is a guide
sticker, which tells positions of selecting switches and program numbers (see also page 6).

In the reel cabinet there is 1-MIG synergy panel. On
the MIG synergy panel there are selecting switches for
1-knob MIG synergic curve, selecting switch for 1-knob
MIG crater filling as well as potentiometer for burn back
time adjustment.
