Safety

Danger from incorrect operation and work that is not carried out properly.
This can result in severe personal injury and damage to property.

  • All the work and functions described in this document must only be carried out by trained and qualified personnel.
  • Read and understand this document.
  • Read and understand all the Operating Instructions for the system components, especially the safety rules.

Danger from electrical current and from emerging wire electrode.
This can result in severe personal injury and damage to property.

  • Before starting work, switch off all the system components involved and disconnect them from the grid.
  • Secure all system components involved so they cannot be switched back on.

Danger from electric current due to defective system components and incorrect operation.
This can result in severe personal injury and damage to property.

  • All cables, leads, and hose packs must always be securely connected, undamaged, correctly insulated, and adequately sized.

Danger from coolant leakage due to unsealed coolant hoses.
There may be a risk of slipping and damage to property.

  • When disconnecting a welding torch from the cooling unit or wire feeder, always seal the coolant hoses using the plastic seal attached to the torch.

Danger due to hot welding torch components and coolant.
Serious burns may result.

  • Allow all welding torch components and the coolant to cool down to room temperature (+25 °C or +77 °F) before starting any of the work described in this document.

Danger due to the operation of water-cooled welding torches without coolant.
This can result in damage to property.

  • Never use water-cooled welding torches without coolant.
  • During welding, ensure that the coolant is circulating correctly – this will be the case if a regular return flow of coolant can be seen in the coolant container of the cooling unit.
  • The manufacturer will not be liable for any damages due to non-observance of the above mentioned points. All claims against the warranty are void.

Intended use

The TIG manual welding torch is intended solely for TIG welding and TIG brazing in manual applications.
Any other use is deemed to be “not in accordance with the intended purpose.” The manufacturer shall not be liable for any damage resulting from such improper use.
Intended use also means:

  • Following all the instructions in the Operating Instructions
  • Carrying out all the specified inspection and maintenance work.

Technical Data

General

This product meets the requirements set out in standard IEC 60974-7.

The performance data specifications only apply when using standard wearing parts.
When using gas lenses and shorter gas nozzles, the welding current is reduced.

The welding current specifications apply to gas-cooled torch bodies only from a length of 65 mm (2.56 in.).
When using shorter torch bodies, the welding current is reduced by 30%.

When welding at the power limit of the welding torch, use larger tungsten electrodes and gas nozzle opening diameters to increase the service life of the wearing parts.
Take amperage, AC balance, and AC current offset into account as performance- enhancing factors.
