temperature is 25ºC and lead temperature is 85 ºC.

Cable Duty cycled ed Voltage loss /10 m

100% 60% 30%

50mm² 285 A 370 A 520 A 0,35 V/ 100 A

70 mm² 355 A 460 A 650 A 0,25 V/ 100 A

95 mm² 430 A 560 A 790 A 0,18 V/ 100 A

Do not overload welding cables due to voltage losses and heating.

Fasten the earthing press of the return current cable carefully, preferably direct onto the piece to

be welded. The contact surface of the press should always be as large as possible.
