8.4.3 Connection of the MIG Push/Pull- Torch (Option)
Description of function, Push / Pull Torch:
An essential prerequisite for high welding economy and weld seam quality is an unimpaired welding
wire feed. This is particularly problematic with:
•
The use of long hose-packs,
•
Welding wires which do not slide easily,
•
Welding wires with low resistance to kinking,
•
the need for particularly smooth wire-feed speeds.
In such cases an additional feed assistance within the welding torch gives drastic improvements over
purely push wire-feed units.. In addition to the pushing wire-feed rollers (PUSH) in the power source
or the wire-feed unit, an additional pulling drive (PULL) is used in the torch.
A current regulator synchronises the two wire-feed motors.
All standard Push/Pull- torches with Euro central connections such as, for example: Binzel,
Dinse, Autogen Ritter and TB can be connected.
Welding torch with one setting knob:
The wire-feed correction can be made using the setting knob on the torch.
(The adjustment knob on the control is deactivated.)
Prerequisites for the connection of a Push/Pull Torch:
•
The welding machine must be prepared for the connection of this torch (Option).
•
The welding torch socket must be wired to correspond with the torch used.
8.5 Installing the Welding Wire
To achieve optimum wire-feed, it is essential to use wire-feed rollers which suit the diameter of
the welding wire used and the type of material (Change if necessary)!
8.5.1 Insertion of the Wire Spool
Standard hub spools D300 can be used. For use of the standardised basket spools
(DIN 8559) an adapter is needed (see Accessories).
