General remarks

Basic system
principle
Fig. 1 TP 2500 welding machine
An electronic adjuster adapts the power source characteristic to the electrode to be
welded. Selectable modes provide perfect welding results when using rutile electrodes,
basic electrodes or cellulose electrodes (CEL).
All versions of the TP 2500 power source are small and compact, yet at the same time

Machine concept

so robust that they will function reliably even under harsh conditions. A powder-coated
sheet steel housing with stainless steel runners, controls and connection sockets (with
bayonet fixing) protected by a plastic frame satisfy the highest demands. The handle
facilitates easy transportation, both in-house or on-site.
In addition to the many features of the standard TP 2500 power source, the TP 2500
VRD, TP 2500 TIG and TP 2500 TIG VRD versions offer a further raft of options.

Application areas

In addition to rod electrode welding, the machines in the TP 2500 series also offer
convenient functions for TIG welding, e.g. touchdown ignition and the practical TIG
Comfort Stop (TCS). The TP 2500 TIG also has the TIG pulsed arc welding mode.
Thanks to their small dimensions, the machines in the TP 2500 series are especially well
suited to portable use on building sites and for assembly work. But even when used as
stationary units in workshops or industrial facilities, the machines are powerful and
economical alternatives.
The TP 2500 power source is a further
highlight of the new generation of welding
inverters. Using powerful electronics, a
unique high-capability, lightweight welding
machine has been created.
The power source works on resonance
inverter principles and therefore offers a
number of advantages:
- Intelligent control for stable arc and
ideal characteristic
- Excellent ignition and welding proper-
ties, extremely lightweight with the
smallest dimensions
- High switching frequencies and
optimum efficiency
