Water cooling:

The device is equipped with an internal water cooling unit with coolant, which ensures efficient cooling of the MIG/MAG torch at high welding currents and longer duty cycles.

According to the rating plate of the specific device:

• cooling unit output P₁: 1.05 kW
• maximum cooling circuit pressure: 3.5 bar

Water cooling is a significant advantage, especially during intensive high-current welding, as it helps maintain an appropriate torch temperature and increases comfort during long-term work.

Dimensions and approximate weight

Official documentation states the dimensions depending on the welding power source version as approximately:

• 1116 × 463 × 812 mm – version A
• 1116 × 445 × 855 mm – version B

The basic weight of the S8 in version A is approximately 107.3 kg, while the filled water cooling system represents approximately a further 14.7 kg. The actual weight of the complete set offered, including the torch, cables, coolant and accessories, may therefore be approximately 125–135 kg.
