© COPYRIGHT KEMPPI OY6 – Minarc 150AU / 04113.1.2. TIG weldingIn DC TIG welding, the arc between a non-melting tungsten electrode and the work piecemelts the work piece, thus forming a weld pool. Arc and electrode are shielded by an inertshielding gas (Argon). If necessary, filler can be used. Filler wire is fed into the weld poolfrom the outside of the arc. Filler and rate of welding current are selected on the basis ofdiameter of tungsten electrode and welding position.3.2. OPERATING FUNCTIONSSee also 2.4. Main components and 3.4. Welding selections.A Signal light VRD safe ONB Welding process selecting switchC Welding current regulatorD Signal light for overheatingE Table of suitable electrodesMain switch and signal lightWhen you switch the main switch at the back of machine to position I, signal light on mainswitch is lit and the unit is ready for welding. Signal light is always on when the unit isconnected to the mains and the main switch is in position I.Note! Always start and stop the machine from the main switch, never use the plugas a switch!Signal light VRD safe ON (A)The machine is equipped with an OCV reduction circuit. The signal light is lit when thecircuit is activated and the unit is in working order.Welding process selector, MMA / TIG (B)Switch is used for selecting either MMA or TIG welding, depending on welding target.When you have switched the unit to TIG welding, VRD is constantly active, thus reducingterminal voltage to 30 V. This facilitates arc cut-off when you stop welding.Regulating the welding current (C)Welding current rate is regulated steplessly with an adjusting potentiometer.Signal light for overheating (D)A yellow signal light for overheating is lit when thermostat has tripped due to the unit’soverheating. Fan will cool the unit and after the signal light goes off, the unit is againready for welding.3.3. WELDING SELECTIONS3.3.1. Manual Metal Arc welding (MMA)Select welding parameters according to filler manufacturer’s recommendations.1. Select polarity (+ or -) of welding current cable and return current cable accordingto filler.2. Select MMA welding with the switch .3. Select suitable welding current by adjusting the potentiometer according to table ofsuitable electrodes (E).BCEADRAMIRENT |
