WELDING SOURCE
   

Depending on the chosen welding practice the unit is supplied with the corresponding welding current source:
-Welding with the use of solid wire (7018 or other) in CO2.
A source for MIG/MAG welding with a controlled metal transfer (surface - tension transfer STT).
Provides "root pass" welding with a quaranteed back bead. The welding process with the controlled metal transfer provides a quaranteed back bead forming in all attitudes.
-Welding with the use of self-shielding wire (innershield or other) in CO2 or argon mixtures.
The Unit may be used, for example, in the following combinations:

1. Welding of all runs with solid wire 7018 in CO2.
 Applicable only for pipes not thicker than 10-12mm.

2. Welding of the root run with solid wire 7018 in CO2.
 Welding of the rest runs with flux- cored wire of FilArc type in CO2.

3. Welding of the root run with solid wire 7018 в CO2.
 Welding of the rest runs with self-shielding wire of Innershield NR207 or NR208 type.

4.  Welding of the root run with a stick electrode.
  Welding of the rest runs with self-shielding wire of Innershield NR207 or NR208 type.


5. Welding of the root run with self-shielding wire of Innershield NR204  type
 Welding of the rest runs with self- shielding wire of Innershield NR207 or NR208 type.
