DESIGN FEATURES
Control Panel
Both the engine and the welder controls are located on one recessed panel at the exciter end of the machine. The welder controls consist of a five step “Current Range Selector” switch and a “Fine Current Adjustment” rheostat. The welder is equipped with a “Start” button, an “Ignition” switch, an “Idler” control switch, and a “Glow Plug” button for easier cold weather starting.
The control panel also contains an engine tempera- ture gauge, a battery charging ammeter, an oil pres- sure gauge, two three prong grounding type recepta- cles and circuit breakers for auxiliary power.
All Copper Windings - For long life and dependable operation.
Engine Idler - The Classic 300D is equipped with an electronic automatic engine idler. It automatically increases and decreases engine speed when start- ing and stopping welding or using auxiliary power. A
Auxiliary Power - 3.0 kVA of nominal 115/230V, 60Hz, AC. Output voltage is maintained within ± 10% at all loads up to rated capacity. (See Optional Features for Power Plug Kit.)
Welder Enclosure - The complete welder is rubber mounted on a rugged steel “C” channel base.
The output terminals are placed at the side of the machines so that they are protected by the door. The output terminals are labeled (+) and
Cranking System - A 12 volt electric starter is stan- dard.
Air Cleaner - Heavy duty two stage dry type.
Muffler - A muffler and stainless steel exhaust outlet elbow are standard.
Engine Hour Meter - A meter to record hours of oper- ation.
Engine Protection - The system shuts the engine down in the event of sudden low oil pressure or high coolant temperature. A warning light on the control panel will indicate such a fault. To reset the engine for restarting, turn the ignition switch off then on.
Refer to Troubleshooting section for all warning light fault codes.
High Idle RPM (OCV) Adjustment - A Potentiometer is mounted on the Control Panel that allows the oper- ator to adjust the high idle engine speed between 1650 and 1800 RPMʼS. This is to allow further adjust- ment of the OCV. Total OCV adjustment range is about 15 volts.
Oil Drain Valve - A ball valve, hose and clamp are standard.
Remote Control - The Remote/Local switch and Receptacle are standard.
GFCI Receptacle - One UL approved 115V ground fault circuit interupter duplex type receptacle is stan- dard on codes 11243 and above. See MAINTE- NANCE section for detailed information on testing and resetting the GFCI receptacle.
