Product description
General The MTG 400i K4 and MTW 500i K4 fume
extraction torches detect the harmful wel-
ding fumes that develop during welding,
right at the point of origin.
The welding fumes are extracted before
they reach the welder's breathing zone.
This ensures the legally prescribed values
for the maximum allowable concentrations
(MAC) remain below or at the required
levels.

tions:
