Crater filling (1-knob MIG, 4-T and 4-TL)
Crater filling is used to reduce weld defects caused by
end crater. At the weld end you get, during gun´s start
switch pressing, a steplessly decreasing welding pow-
er, which fills end crater in a controlled way.
MIG Minilog ( 1-knob MIG 4-TL ) function
In the MIG minilog (4-TL) function remote (C 110D) or gun control (RMT 10) unit is connected to the FEED wire
feeder. Then two sets of welding parameters are adjusted. One set of welding parameters is adjusted from
remote/gun control unit and another set of welding parameters is adjusted from local controls of the panel.
These two levels of welding parameters can now be selected from the trigger of welding gun by pressing it long
or short time (see pictures below).
This function can be benefitted e.g. for avoiding welding faults at start by starting either with higher values than
normal welding values (hot start) or with lower values. Quick change possibility of welding values improves weld
pool control by varying air gaps and in position welding. At the weld end you can use lower welding values for end
crater filling.
MIG Minilog use:
1. Select 1-knob MIG and 4-TL functions with panel switches and from the synergy panel a program for filler
wire / gas you are using.
2. Set selecting switch of main controls to remote control, when you are using C 110D or to gun control, when
you are using RMT10.
3. Adjust the desired welding values from the remote or gun control unit, the values are visible in displays and
the welding current LED is illuminated.
4. Adjust from panel potentiometers lower values than the welding values of above mentioned remote or gun
control units. When panel adjustments are made, the MINILOG current level LED lights up and the displays
start showing panel potentiometer values. When adjustments are stopped, the displays revert after a mo-
ment to show remote control unit´s welding values and at the same time the welding current LED lights up.
5. By starting according to enclosed picture with short (< 0.7 s) pressing of gun´s start switch, the welding
starts with values adjusted to local controls and goes over with following < 0.7 s pressing to higher welding
values, which have beed adjusted to the remote control unit.
6. By starting with long (> 0.7 s) pressing of gun´s start switch, the welding starts with values adjusted to remote
control unit and goes over with following short < 0.7 s pressing to lower welding values, which have been
adjusted to local controls.
7. During welding with short < 0.7 s pressings of start switch, the operator is moving between these two current
levels according to needs.
8. The welding is always stopped with long pressing of more than 0.7 s.
9. If necessary you can use crater filling function at the weld end.
