2.8.1
Pulse Width Mode “P/W”
Pulse Width (“P/W”) mode is open loop control. The current and heat parameters are independently adjustable. The
inverter pulse-width is fixed. The current parameter is only used for monitoring. The current target is programmed in
units of % heat.
2.8.2
Constant Current Uncalibrated Mode “CCu”
Constant Current Uncalibrated (“CCu”) mode uses a variable pulse
-width to determine and regulate the actual current.
The current and heat parameters are independently adjustable. The current parameter is used for monitoring only. The
current target is programmed in units of % heat.
2.8.3
Constant Current Calibrated Mode “CCC”
Constant Current Calibrated (“CCC”) uses a variable pulse
-width to determine and regulate the actual current. The
current parameter is adjustable by the user but the heat is automatically adjusted by the iPAK2 weld control. The
current target is programmed in units of kiloampere (kA).
