Each device will be recognised automatically The welding machine weight is shown in table 1 (TAB. 1). and can be used to adjust the following parameters: - Remote control with one potentiometer: 4. DESCRIPTION OF THE WELDING MACHINE turning the potentiometer knob will change the main current from the minimum to the 4.1 BLOCK DIAGRAM The welding machine consists basically of power modules made on PCB's, optimised to achieve outstanding reliability and reduced maintenance. maximum. The main current is adjusted only and exclusively by the remote control. - Pedal remote control: The current value is determined by the position of the pedal. In TIG 2-STROKE mode pressing the pedal gives the start command to the machine instead of the torch button (if present). - Remote control with two potentiometers: the first potentiometer adjusts the main current. The second potentiometer adjusts another parameter, depending on the active welding mode. When this potentiometer is turned the display will show the changing value of the parameter (which can no longer be controlled with the knob on the panel). In MMA mode it regulates ARC FORCE and in TIG mode, for welding machines with HF/LIFT strike it adjusts the SLOPE DOWN. - TIG-PULSE remote control (for the TWIN CASE welding machine and 3-phase model with HF/LIFT strike): used for TIG welding with pulsed direct current, with the possibility of remote control adjustment of the most important parameters: base current intensity, pulsed current intensity, duration of pulsed current, period of pulsed current. This procedure gives greater control of heat transfer, making it possible to weld materials that are thin or have a tendency for hot cracking, and it is also suited to welding pieces of varying thickness and dissimilar steels such as stainless and low- carbon steel.

WELDING: DESCRIPTION OF THE PROCEDURE - The properties of the weld also depend on the ARC-FORCE value (dynamic General principles TIG welding is a welding procedure that exploits the heat produced by the electric arc behaviour) of the welding machine. The setting for this parameter can be made (when that is struck, and maintained, between a non-consumable electrode (tungsten) and the available) at the control panel, or else using the remote control with 2 potentiometers. piece to be welded. The tungsten electrode is supported by a torch suitable for - It should be noted that high ARC-FORCE values achieve better penetration and allow transmitting the welding current to it and protecting the electrode itself and the weld pool welding in any position typically with basic electrodes, low ARC-FORCE values give a from atmospheric oxidation, by the flow of an inert gas (usually argon: Ar 99.5) which softer, spray-free arc typically with rutile electrodes. The welding machine is also equipped with HOT START and ANTI STICK devices to flows out of the ceramic nozzle (FIG. M). guarantee easy starts and to prevent the electrode from sticking to the piece.

The electrode usually protrudes from the ceramic nozzle by 2-3mm, but this may reach 8mm for corner welding. CHARACTERISTICS OF THE WELD BEAD (FIG. R) Welding is achieved by fusion of the edges of the joint. For properly prepared thin pieces (up to about 1mm) weld material is not needed (FIG. O). 7. MAINTENANCE For thicker pieces it is necessary to use filler rods of the same composition as the base material and with an appropriate diameter, preparing the edges correctly (FIG. P). To achieve a good weld the pieces should be carefully cleaned and free of oxidation, oil, WARNING! BEFORE CARRYING OUT MAINTENANCE OPERATIONS MAKE grease, solvents etc. SURE THE WELDING MACHINE IS SWITCHED OFF AND DISCONNECTED FROM THE MAIN POWER SUPPLY HF and LIFT strike HF strike: The electric arc is struck without contact between the tungsten electrode and the piece being welded, by means of a spark generated by a high frequency device.
