Soft Start (Acc).

This regulation is important in order to obtain good starts.
Soft start is the wire speed, expressed in percentage of wire speed set for welding, before that the wire
touches the workpiece.
Press for a time longer than 3 seconds the key E to enter the "Second Functions" menù.
Use knob N to select Acc on display O; with knob Q select the Soft Start speed level, visible on display P
(indication expressed in percentage).
Regulation range: Auto or 1 ÷ 100%, default = Au, automatic.
NOTE: In order to verify the value corresponding to the default value, rotate of a single step clockwise
the knob Q, when display P indicates Au, and subtrac "1" to the value that appears on display P.

Burn-Back Time Correction (bb).

Regulation for the wire length exiting the torch nozzle after welding, expressed as a time interval
GB
(milliseconds).
Press for a time longer than 3 seconds the key E to enter the "Second Functions" menù.
Use knob N to select bb on display O; display P shows the function value (indication expressed in
milliseconds).
Correction regulation range: -125 ÷ +125 ms.
The Burn-Back Time effective value after the correction is always comprised between 4 ms. and 250 ms.
When the correction set up is equal to 0 the Burn-Back Time parameter is set to its default value,
indicated with Au (automatic).
The Burn-Back Time Correction adjustment is enabled or disabled by means the Burn-Back Time
Correction Disable function, available on RAI211 and RDI210 Robot Interfaces.
The corresponding bit is controlable with dip switch S1-4 on RAI211 Robot Interface or with the signal
"I100" of the Data-In Process Image on RDI210 Robot Interface (see Robot Interface Instruction
Manual):
- with "Burn-Back Time Correction Disable" not active (S1-4 = OFF, or I100 = low) the "Burn-
Back Time Correction" adjustment is enabled in Standard program, Pulsed arc program and
Manual modes, and follows the value set at Robot Interface analog input 4. The adjustment is carried
out via Robot Terminal;
- with "Burn-Back Time Correction Disable" active (S1-4 = ON, or I100 = high) the "Burn-back
Time Correction" is not active.
Independently from the Burn-Back Time Correction Disable function state, in Parameter Selection
Internal mode, is always possible to adjust the Burn-Back Time Correction from Control Panel.
When the Control Panel is operating, knob Q executes the "Burn-Back Time Correction" function
value regulation and the key AZ, pressed for a time longer than 3 seconds, resets the function to the
default value (Au on display P).
NOTE: In order to verify the value corresponding to the default value, rotate of a single step clockwise
the knob Q, when display P indicates Au, and subtrac "1" to the value that appears on display P.
Obviously, after such operation, rotating counter-clockwise of a single step knob Q, the operation
will be set to the value visible on display P, but not automatic. In order to restore the automatic
operation (default) press for a time longer than 3 seconds the key AZ.
Press briefly the key E to exit the "Second Functions" menù, saving all current settings automatically.
