Technical Characteristics - GALAGAR Gar AC/DC 180 Technical Instruction Manual

CHAPTER 1 GENERAL DESCRIPTION. TECHNICAL CHARACTERISTICS
The Gar
electromechanical appliances to be used for manual
welding with coated electrode and T.I.G. procedure.
With single-phase connection, the welding
current is continuously adjusted by magnetic shunt.
The Gar AC/DC models have two welding
working modes:
- A.C. working mode: Alternating welding current
- D.C. working mode: Direct welding current.
The main advantages of this equipment
opposed to traditional alternating current appliances
are the following:
• Possibility of welding a wide catalogue of
electrodes in D.C. working mode (basic,
aluminium, bronze) providing high arc stability
and obtaining top quality professional results.
Possibility of welding with T.I.G. procedure in
•
D.C. working mode.
welding of normal and stainless steels with
thicknesses varying from 0.5-0.8 mm to 2-3
mm.
• Possibility of welding with 4 mm diameter
rutile electrode with 160A and 35% operating
factor in A.C. working mode.
This enables professional work to be carried
out with a good operating factor.
