2.1 General area of application and functions
2.1.1 Area of application
TBi PP-TX welding torches were developed as an easy way to upgrade available MIG/MAG welding power
sources into a high-performance Push-Pull system.
Considerably longer cable assemblies can be used with the Push-Pull torch. Wires that are difficult to handle
e.g. AlMg wires can be easily fed over distances of up to 12 m through the additional wire feed system in the
torch handle. The welding process remains stable due to the even wire feed speed.
The powerful wire feed with large feed roll provides optimal performance whilst protecting the wire.
TBi PP-TX welding torches are equipped with easily changeable torch necks. Thus the torch can be optimally
adjusted to changing tasks. Even in the event of a faulty neck, work can continue immediately with a spare
neck.
The neck can also rotate in the holder. This also makes many tasks easier.
The handle was manufactured using 2-component technology and provides an appealing, ergonomic shape
with optimised non-slip properties. The drive mechanism is easily accessible thanks to the large cover. The
contact force of the feed roll can be adjusted over a wide range.
The torch is also available with two easily accessible, integrated potentiometers. These can be connected to the
remote control interface of the power supply.
2.1.2 Function
The wire feeding system integrated into the handle of the TBi PP-TX torch supports the main feed unit of the
power source for the wire feed. Therefore, the friction of the wire in the cable assemble no longer has a direct
impact on the wire speed, the wire is fed at a consistent speed.
In the drive unit, the wire is pressed into the groove of the driven feed roll by a smooth pressure roll. A high
feeding force can thereby be transferred without deformation of the wire.
In the simplest case, the Push-Pull motor is connected in parallel to the main drive motor using the control board
supplied. This automatically adjusts the speed of the Push-Pull drive. Alternative connection types are possible
through additional controls.
The optional remote control potentiometers can be connected to the remote control interface of the power
source via the torch control cable. Different welding parameters can be conveniently changed directly on the
torch, depending on the functional range of the power source.
