Page 5: Section 2 - Specification
SECTION 2 — SPECIFICATION 2.1 - Description The RT4000 is a 400A (500A for the RT5000) constant current welding power source based on IGBT technology. The Inverter drive circuitry operates above the audio fre- quency spectrum making the RT4000/RT5000 virtually silent in operation. The high op- erational frequency also means that the RT4000/RT5000 is able to respond quickly to changing arc dynamics, making for a very smooth and stable arc. -

SECTION 4 — OPERATION 4.1 Operating Controls and Connections 4.2 Description of controls 1. TIG2/TIG 4 switch - This control switches between 2s and 4s operation (normal and latch). In TIG2 position, when the torch switch is pressed the arc ignites, when the switch is released the arc goes out. In TIG4 position, when the torch switch is pressed and released the arc ignites, to extinguish the arc you must press and release the torch switch again. - Page 8 Adjust the Arc Force control to your personal preference for the size and type of welding electrode to be used. The RT4000/RT5000 is suitable for welding all types of electrodes within the current rating of the machine (see Technical Data) The RT4000/RT5000 should never be used with arc-air gouging or cutting electrodes.

Page 9: Section 5 - Fault Finding And Maintenance
Make sure that the display is not reading ‘HOT’, • TIG welding follow the check list below, this will if it is, it means that the RT4000/RT5000 has over- cure most problems :- heated, normally by exceeding its ’Duty Cycle’, and the power stages of the machine have been shut down. -
Page 10: Maintenance
Note! All Electric shocks are potentially fatal, switch off the machine and unplug from the mains supply before carrying out any maintenance work. It is very important that the RT4000/RT5000 is regularly maintained. The amount of use and the working environment must be taken into account when scheduling the maintenance periods. -
