CHAPTER 1. GENERAL DESCRIPTION. TECHNICAL CHARACTERISTICS.
This equipment forms part of a modular system (INDUSTRIAL GALA) that permits electric welding of carbon
steels, slightly alloyed steels, stainless steels and aluminium, which are the most commonly used metals in
modern industry, by means of the MIG-MAG semiautomatic procedure.
The whole modular system that makes up the installation comprises the following elements:
1.1 – Power source. (Earth cable included).
1.2 - Wire feed unit (Independent from the power source).
1.3 - Connection extension lead between power source and wire-feed unit. Welding torch.
1.4 - Cooling module for cooled welding gun.
1.5 - Transport trolley (compulsory if a cooling module is installed) or bottle support.
1.6 - Auxiliary elements: Pressure reducing valve for gas bottle, gas economiser.
1.1. POWER SOURCES: GALA MIG 3007 / GALA MIG 4007
GALA MIG 3007: CV power source (flat characteristic) with staggered adjustment (20 adjustment points).
MIG/MAG welding.
GALA MIG 4007: CV power source (flat characteristic) with staggered adjustment (30 adjustment points).
MIG/MAG welding.
NEVER USE THESE WELDING MACHINES TO DEFROST TUBES.
