4. GENERAL CHARACTERISTICS

THERMAL ARC 180 AC/DC welding machines have been designed as integrated and portable units
using the newest techniques in power electronics, based on an inverter process with IGBT, wich
enables the following :
- a considerable reduction of weight and volume
- the dynamic control of the welding current
- the specific protection of power components
- a high power in a small space at a very low power consumption
With their innovative design, these machines are both robust (plastic front and back panel, new
internal conception) and ergonomic.
THERMAL ARC 180 AC/DC units have built-in over voltage protection.
These units can be supplied by engine driven generators
They offer a very high quality of welding in :
1- stick welding
Exceptional arc characteristics with a microprocessor that ensures regulation and perfect blade
appearence and spatter control.
Maximum user's comfort strengthened by arc force and anti stick.
2- TIG welding
Ignition of the arc can be made with high frequency or using a lift arc technique, either in 2 stroke or
in 4 stroke modes.
Welding with DC or AC current
Integrated pulse current, totally controlled through the microprocessor.
Powerful and direct H.F
Female socket on the back side for a direct connection to a cooling unit
These power sources are perfectly suited to welding in :
- TIG DC for high alloyed steels, stainless steels, copper and copper alloys, titanium ...
- TIG AC for aluminium and its alloys, magnesium.
- Stick welding with coated electrodes of all types in positive or negative polarity.
