RECOMMENDED APPLICATIONS

WELDER

The Classic I provides excellent constant current DC welding output for stick (SMAW) welding and for DC TIG welding. For more details on using the machine as a welder, see Welding Operation in the Operation section of this manual.

GENERATOR

The Classic I is also capable of providing 1.75 kw of 115V DC auxiliary power.

OPERATIONAL FEATURES AND CONTROLS

The Classic I was designed for simplicity. Therefore, it has very few operating controls. Two switches are used for welding operations:

•A five-position CURRENT RANGE SELECTOR switch selects current output ranges for constant cur- rent stick or TIG applications and constant voltage wire feed applications (with optional Wire Feed Module - see the Accessories section)

DESIGN FEATURES

•Constant current DC Stick welding (SMAW) process capability with output range from 40 - 300 DC amps.

•Work and Electrode welding cable mounting termi- nals.

•Separate ground stud for safe connection of case to earth ground.

•115 volt DC auxiliary power receptacle.

•Electric starting.

•Distributor type electronic ignition.

•Battery Charging Ammeter.

•Engine Hour Meter for determining periodic mainte- nance.

•Top-of-the-line 38 HP Continental gasoline engine.

•Top-mounted 15 gallon (57.0 litter) fuel tank with con- venient top fill.

•Automatic engine idler goes to low idle approximate- ly 15 seconds after welding for greater fuel economy; includes high idle switch.

•A FINE CURRENT ADJUSTMENT control for fine adjustment of current from minimum to maximum within each range

Controls for the gasoline engine control include a two- position IGNITION ON/OFF toggle switch, a START pushbutton, and a two-position IDLER switch that selects engine speed for welding or auxiliary power applications. See Engine Operation in the Operation section of this manual for details about starting, run- ning, stopping, and breaking in the gasoline engine.

WELDING CAPABILITY

The Classic I is rated 200 amps, 40 volts constant cur- rent DC at 60% duty cycle based on a ten minute time period. Longer duty cycles at lower output currents are possible.

The current is continuously variable from 40 to 300 amps DC.

LIMITATIONS

The Classic I is not recommended for any processes besides those that are normally performed using DC stick welding (SMAW) and DC TIG welding. Specific limitations on using the Classic I for these processes are described in the Welding Operation section of this manual. Constant voltage welding is available with the optional Wire Feed Module.
