Read this entire installation section befor e you start installation. SAFETY PRECAUTIONS ELECTRIC SHOCK can kill. • Do not touch electrically live parts or electrodes with your skin or wet clothing. • Insulate yourself fr om the work and ground. • Always wear dry insulating gloves.
INPUT CONNECTIONS ELECTRIC SHOCK can kill. • Have a qualified electrician install and service this equip- ment. • T ur n the input power off at the fuse box before working on this equipment. • Do not touch electrically hot parts. • Insulate yourself from the work and gr ound.
Have a qualified electrician connect the input power leads to the L1, L2, and L3 terminals of the input con- tactor . Follow all national and local electrical codes. Use a three-phase line. Refer to the connection dia- gram located on the inside of the access panel cover for proper input voltage connection.

GENERAL DESCRIPTION The Idealarc R3R is an SCR contr olled constant cur- r ent DC output power sour ce for welding and cutting. The R3R-300 uses a single range potentiometer con- tr ol. The R3R-400 and R3R-500 have separate low and high range controls.
CONTROLS AND SETTINGS All operator controls and settings ar e located on the case front assembly . See Figure B.1 for their loca- tions. FIGURE B.1 – CASE FRONT CONTROLS 1. POWER SOURCE PILOT LIGHT : This light indi- cates that input power is applied to the R3R and that the on/off switch is in the ON position.

GENERAL DESCRIPTION The Idealarc R3R welder is a thr ee-phase transformer r ectifier type constant curr ent power sour ce designed for DC manual welding and air carbon arc cutting. Its power system is SCR controlled with solid state elec - tr onic cir cuitry .
OUTPUT RECTIFICA TION, CONTROL, AND FEEDBACK The three-phase AC output fr om the main transformer secondary is rectified and contr olled through the SCR/ diode bridge. Output current and voltage is sensed at the shunt and output terminals. This feedback infor- mation is processed in the contr ol board.
THEOR Y OF OPERA TION E-4 E-4 IDEALARC R3R Return to Section TOC Return to Section TOC Return to Section TOC Return to Section TOC Return to Master TOC Return to Master TOC Return to Master TOC Return to Master TOC FIGURE E.
PROTECTIVE DEVICES AND CIRCUITS T wo thermostats protect the R3R from excessive operating temperatures and overload conditions. Excess operating temperatures may be caused by insuf ficient cooling air or by operating the machine beyond the duty cycle and output rating.
SCR OPERA TION A silicon controlled r ectifier (SCR) is a three terminal device used to control rather lar ge currents to a load. An SCR acts very much like a switch. When a gate signal is applied to the SCR, it is turned ON and there is current flow fr om anode to cathode.
