WH TANDEM W800 (liquid cooled)

WH TANDEM W800 (liquid cooled)

Tandem welding makes high demands on the whole equipment. The WH W800 is a reliable and technically matured torch for welding in the high-power range.

Based on the tried-and-trusted WH system, almost all welding applications in this range can be carried out using the WH W800 – thanks to the different torch geometries. Three individual cooling circuits guarantee optimum temperature behaviour.

  • Simple and quick maintenance
  • Use of standard WH cable assemblies
  • Quick-action connection for gas nozzle, different contact tip lengths available
  • Optimally matched to the power source technology of various manufacturers
  • Compact and powerful with two separate potentials
  • Three individual cooling circuits (gas nozzle and both cable assemblies)
