Characteristics Of The Mec 4 Torch - Lincoln Electric MEC 4 Safety Instruction For Use And Maintenance

B - DESCRIPTION
Both versions offer the following possibilities:
 Easy removal of the electrode holder from the top of the torch body, for more
speed and no risk of upsetting the mechanical adjustment of the torch.
 Pre-adjustment (outside the torch) of the emerged length of the electrode in
relation to the end of the protective nozzle. That pre-adjustment is carried out with
an adjustable tool delivered with the torch.
 The parallelepiped shape of the outer body of the torch makes it easier to take
a positioning reference.
 The MEC4 torch is cooled by water circulation and can easily withstand the
most stringent welding requirements up to 500A at 100% (except version
W000315610, limited to 250A at 100%.
 As an option, straight and bent MEC 4 torches may be instantly fitted with the
following additions:
