1.2 Machine Components
RD 500 E is thyristor (SCR) controlled welding machines, designed to weld all type of coated electrodes from 2.0mm up to 5.0mm, also carbon electro-
des up to 8.00mm. RD 500 E 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 RD 500 E 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 ele-
ctrodes 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.
