Fronius MTG 250i Exento Fume Extraction Torch

Product Information

Exento Fume Extraction Torch

The Exento Fume Extraction Torch is a welding torch designed for capturing and separating welding fumes directly at the source. It fulfills the requirements of the EN ISO 21904-1 norm for occupational health and safety in welding and allied processes. The torch features improved accessibility, regulation of extraction power, LED lighting of the welding point, and standard wear parts of the TPSi generation.

Product Usage Instructions

• Regulation of the Extraction Power on the Welding Torch
  • The Exento Fume Extraction Torch allows you to regulate the extraction power for different welding scenarios.
  • The standard setting is closed. Opening the bypass slider reduces the extraction rate by approximately 40%. This can be useful in preventing the extraction of shielding gas in corners or narrow welding spots.
• LED Lighting of the Welding Point
  • The torch is equipped with LED lighting for illuminating the welding point before and after welding. The lighting can be controlled via the two-step torch trigger.
• Standard Wear Parts of the TPSi Generation
  • The Exento Extraction Torch is designed with standard wear parts of the TPSi generation. These wear parts are compatible with the torch and can be easily replaced when needed.
• Exentometer (Optional)
  • The Exentometer is an optional accessory that can be used for precise adjustment of the optimum extraction power. The extraction rate depends on various factors such as the welding process, power, material, and welded parts. Each Exentometer is checked before delivery.

Accessibility

Accessibility | Energy Saving

• Improved accessibility: Even without extraction nozzle, the standard ENISO 21904-1 is fulfilled. Therefore best accessibility.
• With extraction nozzle 10% energy saving: Extraction nozzle for best energy-and extraction efficiency.

Regulation of the Extraction

Regulation of the Extraction Power on the Welding Torch

• Opening the bypass: slider reduces the extraction rate by approx. 40%.
• Application example: prevents extraction of shielding gas in corners or narrow welding spots.

Standard Wear Parts of the TPSi Generation

Exento Extraction Torches Fulfill the Norm EN ISO 21904-1

• Extraction torches capture and separate welding fumes directly where they are generated.
• They fulfill the requirements of the EN ISO21904-1 norm for occupational health and safety in welding and allied processes.

Option Exentometer

Option „Exentometer“ 44,0350,2079

• The measuring tube is used for precise adjustment of the optimum extraction power
• The optimum extraction rate depends on many things, welding process, power, material, welded parts….
• Example MTG 400i: According to the norm, a value of at least 57 m³/h extraction rate must be set here. (The value can be found on the rating plate)

Check

• Each Exentometer is checked before delivery.
• The upper Exentometer is designed as a testing device at Fronius and is checked once a year.
• The lower Exentometeris a new one which is tested
• Tested with 55 m³/h
• Tolerance is between +/-5m³/h
