2.3. Current control
The weld programs contain the following current control parameters.
Parameter Units Range Description
Pre-mode
1
PW/CCu/CCC Operating mode of the Pre-heat interval
Pre-heat
1
% 0.0 – 99.9 The % heat used during the Pre-heat interval in
PHA mode
Pre-current
1
kA 0 – 500 The current used during the Pre-heat interval in
CCC mode. Set point for monitoring.
Main mode PW/CCu/CCC Operating mode of the Main heat interval
Main heat % 0.0 – 99.9 The % heat used during the Main heat interval in
PHA mode
Main current kA 0 – 500 The current used during the Main heat interval in
CCC mode. Set point for monitoring.
Post mode
2
PW/CCu/CCC Operating mode of the Post-heat interval
Post heat
2
% 0.0 – 99.9 The % heat used during the Post-heat interval in
PHA mode
Post current
2
kA 0 – 500 The current used during the Post-heat interval in
CCC mode. Set point for monitoring.
Test current on/off Each current can be tested between limits
High limit % 0 - 99 Current high limit

Post-heat program option must be enabled to use this extended feature.
2.3.1. PW mode
PW (Pulse-width) mode. The heat adjusts the output pulse-width. No current regulation
takes place. The current parameter is used for monitoring only
2.3.2. CCu mode
CCu (Constant Current, uncalibrated) mode. The heat adjusts the output current
within the range set by the configuration parameter Ip limit. Current is regulated but
the current parameter is used for monitoring only.
2.3.3. CCC mode
CCC (Constant Current, calibrated) mode. The current parameter sets the output
current directly (in kA). Current is regulated. The current parameter is also used for
monitoring. See Electrode management – CCC calibration.
