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)
• 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.
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.
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.
