TECHNICAL INFORMATION
1.1 General Information
RD 500E, RD 650E are thyristor (SCR) controlled welding machines, designed to weld all type of coated
electrodes from 2.0 mm up to 5.0 mm, provide high carbon gouging performance. Can go as low as 10 Amps,
so it can perform as a DC TIG welder as well if a proper TIG starting unit is connected. More than one can be
grouped as 4, 6,8 or 9 machines in a rack, for large construction sites like shipbuilding etc. Due to thyristor
(SCR) and electronic close loop control technology, current is adjusted precisely by a potentiometer, initial
striking ability of the electrodes can be improved via Hot Start potentiometer and certain electrodes like
basic electrodes which have tendency to short circuit and stick to the weld pool could be avoided by
adjusting the Arc Force potentiometer. Also due to this technology, pre-adjusted current stays stable even
during mains fluctuations or if additional welding cables are used. Even though there is a certain level of
electronics is involved in this machine, the PCB is protected in a separate cabinet inside of the machine
against dust and corrosion. With its telescopic arms and big wheels it can be pulled easily across the working
area especially at outdoor welding sites. Also stepless remote current controlling is possible as an option.
These machines are fan cooled and thermally protected against overheating and phase failures.
