Technical description
The plasma arc welding machines
PLASMAWELD 202 and 402 have been developed for welding
with transferred arc, i. e. the main arc transfers from the tungsten to the work piece.
These units can also be used for TIG, TIG pilot arc and manual metal arc (MMA) welding.
The power supplies can be used in confined spaces and are labelled with the S-mark according to EN
60 974-1.
Infinitely variable adjustment of the welding current makes the units suitable for micro-plasma and
high current plasma as well as for plasma key hole welding.
The pilot arc , started by HF, remains ignited and permits safe and touch-free starting of the main
arc.
By means of rh 19“ rack control system, the units can be used for all manual and automatic plasma
welding applications.
The required welding current and gas flow can be preset before starting the welding operation.
The power supplies are equipped with a constant current control so variations of the mains voltage or
different arc length do not effect the current of the main arc.
The following materials can be welded:
high-, low- and unalloyed steel; nickel, copper, titanium , zirconium and their alloys.
The compact construction with built in water cooler for the torch enables easy transportation of the
machines.
WARNING
This product is intended for industrial use (Class A). In a domestic environment this product may
cause radio interference. It is the users responsibility to take adequate precautions.
The welding equipment creates a noise level of < 70 dB(A) at idle.
An emission level related to the work-place cannot be stated, because this value is depending on the
method and the surroundings. It is conditioned by a variety of parameters e.g. the welding or cutting
process, the kind of current, the power, the kind of material, resonance’s of the workpiece, the
surroundings and more.
