P/W (constant Pulse Width) mode. The current and heat parameters are independently adjustable. The
inverter pulse-width is fixed. The current parameter is used for monitoring only.
CCu (Constant Current uncalibrated) mode.
The current and heat parameters are independently
adjustable. The inverter uses a variable pulse-width to determine and regulate the actual current. The
current parameter is used for monitoring only.
CCC (Constant Current Calibrated) mode.
The current parameter is adjustable but the heat is
automatically determined by the iPAK2 from the calibration data.
The diagram shows how the parameters control the welding current. The Cool2 interval is not shown.
