Welding and earthing cables
The welding and earthing cables are rubber-insulated copper cables. The recommended
cross-sections of the cables for different power source models are as follows:
Model
Welding cable
SYN 300
50 ... 70 mm²
SYN 400
70 ... 90 mm²
SYN 500
70 ... 90 mm²
The table below shows the typical load capacities of the cables when the ambient
temperature is 25 ºC and the lead temperature is 85 ºC.
