The Accu-Power feature displays the instantaneous output power while welding, which can then be used with the equation below to compute
the heat input for a particular weld operation.
At end of the weld the total average power in kilojoules per second and total arc time in seconds are displayed for up to 30 seconds on the
Wire and Gas selection display.
To calculate the weld heat input, multiply the instantaneous power by the arc time and divide by the weld bead length.
To convert from kilojoules to joules, multiply this result by 1000.
Enabling Accu-Power
Accu
−
Power is always displayed when using Accu-Pulse. To enable in other welding arc modes, connect voltage sense lead from weld volt-
age sense receptacle on rear of wire feeder to work piece. See section 5-7 for more information.
.
Use the weld voltage sense connection for better accuracy when using this feature.
