CHAPTER 1.
GENERAL DESCRIPTION. TECHNICAL CHARACTERISTICS.
The GAR CONTINUOS equipment line groups together a set of INDUSTRIAL arc electric welding
appliances. Designed for OUTDOOR work, they are characterised by their HIGH DUTY CYCLE, and the
possibility of REMOTE CONTROL given that they incorporate an electronic power control system by means of
thyristorised rectifier. Some large-diameter wheels, as well as a weight compensation system provide easy and
simple transport. The GAR CONTINUOS LINE of welding equipment is the ideal solution for work on large
structures. This line responds to the huge demands established by modern industry, where difficult and
gruelling work conditions advise the use of extremely robust appliances that satisfy the following premises:
• Optimum welding performance with all kinds of electrodes and in difficult working conditions.
• Handling and control from the actual appliance or remotely.
• Simple handling and transport.
Shipyards, refineries, any structure are application examples.
The basic characteristics of this line are as follows:
• WELDING OF ALL KINDS OF ELECTRODES: BASIC, SPECIAL AND CELLULOSIC.
• T.I.G. PROCESS WELDING WITH "LIFT-ARC" GENTLE ARCING (MINIMUM TIG CURRENT 5 A.)
• POSSIBILITY OF AIR CUTTING IN GAR CONTINUOUS 550 EQUIPMENT
• PURELY INDUSTRIAL CONCEPTION. DESIGN FOR "OFF SHORE" OUTDOOR WORKS.
• POSSIBILITY OF WELDING CURRENT REMOTE CONTROL
• THREE-PHASE SUPPLY. DUAL VOLTAGE 230-400V. 50-60 Hz (220V, 240V, 380V, 415V)
• ELECTRONIC CONTROL IN TRANSFORMER SECONDARY. CONTROLLED RECTIFIER.
A series of technical advantages are obtained with electronic regulation that purely electromechanical
traditionally designed equipment do not have:
• Ideal DESCENDING static characteristic that gives the welding current great stability, which is
INDEPENDENT FROM THE LENGTH OF THE WELDING CABLES (Ideal for large distances to point of
work), as well as from the SUPPLY VOLTAGE VARIATIONS.
• DIGITAL MEASURING SYSTEM for standard welding parameters.
• HOT START adjustable function (Aid for arcing coated electrodes).
• ARC FORCE adjustable function (Arc force that permits recovering the optimum arc length when
welding coated electrodes).
• ANTISTICKING function (Antisticking of electrode).
• Welding function of special electrodes such as cellulose ones.
• LIFT ARC function (The arcing, in TIG welding process, is carried out gently without contamination).
• ARC-AIR CUTTING function in GAR CONTINUOS 550 equipment.
