However , your overall safety can be increased by proper installation .
SAFETY i i CLASSIC I FOR ENGINE powered equipment. 1.a. T urn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running. ____________________________________________________ 1.b . Operate engines in open, well-v entilated areas or vent the engine e xhaust fumes outdoors.
SAFETY ii ii CLASSIC I ARC RA YS can burn. 4.a. Use a shield with the proper filter and cov er plates to protect your e yes from sparks and the ra ys of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87.
CLASSIC I FOR ELECTRICALL Y powered equipment. 8.a. T ur n off input power using the disconnect switch at the fuse bo x before working on the equipment. 8.b . Install equipment in accordance with the U.S. National Electrical Code, all local codes and the manuf acturer’ s recommendations.

CONTROL OF WELDING CURRENT • DO NOT turn the CURRENT RANGE SELECT OR while welding because the current ma y arc between the contacts and damage the s witch. • DO NO T attempt to set the CURRENT RANGE SELECT OR between the fiv e points designated on the nameplate.
GASOLINE ENGINE CONTROLS See Figure B.3 f or the location of the f ollowing f eatures: 1. IDLER CONTROL T OGGLE SWITCH: Adjusts the running speed of the engine. The s witch has two positions, "HIGH" and "A UT O ." In "HIGH," the engine runs continuously at high idle.
ENGINE OPERA TION DO NO T R UN THE ENGINE A T EXCESSIVE SPEEDS. The maximum allo wab le high idle speed for the Classic I is 1550 RPM, no load. Do NO T increase the idle speed on the engine. Se v ere personal injur y and damage to the machine can result if it is operated at speeds abov e the maximum r ated speed.
ST OPPING THE ENGINE 1. Remove all w elding and generator po wer loads and let the engine cool by running it f or se v eral minutes at lo w idle. 2. Place the IGNITION switch in the OFF position. The engine controls were properly set at the factory and should require no adjusting when receiv ed.
WELDING OPERA TION T O USE THE CLASSIC I FOR DC CONST ANT CURRENT STICK OR TIG WELDING: 1. Remove the flange n uts from the weld output ter- minals and place the work and electrode welding cables o v er the terminals. For positiv e electrode, connect the electrode cable to the + terminal and the work cable to –.

SAFETY PRECA UTIONS • Ha ve qualified personnel do all maintenance and troubleshooting w ork. • T ur n the engine off before w orking inside the machine. • Remov e cov ers or guards only when necessar y to perf orm maintenance and replace them when the maintenance requiring their remov al is complete.
CHANGE THE OIL: Change the oil, while the engine is still warm, as follo ws: 1 . Drain the oil from the dr ain plug located on the engine bottom, as shown in Figure D .1. 2. Replace the plug and tighten it securely . 3. Remove the oil fill cap and add oil until the le vel reaches the upper dash full mark on the dipstick.
FUEL FIL TER: Inspect the in-line fuel filter daily . When necessar y remo v e the sediment bo wl from beneath the gas tank and clean out any accum ulated dir t and water . Change the fuel filter after the first 50 hours of opera- tion and e v er y 500 hours thereafter .
F AN BEL T : Fan belts tend to loosen after the first 50 hours of operation. If the fan belt is loose, the engine can overheat and the battery can lose its charge. Check belt tightness by pressing on the belt midway between the pulleys. The belt should deflect no more than 13 mm (0.
B A TTER Y MAINTENANCE GASES FROM BA TTER Y can e xplode. • K eep sparks, flame , and cigarettes a way from batter y . BA TTER Y ACID can b urn eyes and skin. • Wear glo ves and e ye protection and be careful when working near a batter y . F ollow the instructions printed on the batter y .
WELDER/GENERA T OR MAINTENANCE ST ORA GE: Store the Classic I in clean, dr y , protected areas. CLEANING: Blow out the generator and controls peri- odically with low pressure air .
CURRENT RANGE SELECT OR CONT ACTS: The contacts should not be greased. T o keep the contacts clean, rotate the current control handle through its entire range frequently . Good practice is to tur n the handle from maximum to minimum setting twice each morning before star ting to weld.

GENERAL DESCRIPTION The Classic I is a heavy duty , engine driven, DC arc welding pow er source capable of pro viding constant current output f or stick w elding or DC TIG welding. Also , a total of 1750 watts of auxiliary power is a v ailable at the 115VDC receptacle.
ENGINE, MAIN GENERA T OR ARMA TURE AND FRAME AND DC EXCITER EXCIT A TION (FLASHING) The main generator armature and the exciter arma- ture are mechanically coupled to the engine. When the engine is star ted and running, the residual mag- netism that is stored in the e xciter pole pieces is induced upon the e xciter armature.
ENGINE, MAIN GENERA TOR ARMA TURE AND FRAME AND DC EXCITER (CONTINUED) CURRENT RANGE SELECTOR The selector switch acts as a course current adjust- ment by allowing varying amounts of series windings to be included in the welding current path. The series coils and selector switch are connected in series with the negative output terminal.
DC GENERA TOR MACHINES The armature winding of a DC generator is located on the rotating member . Current is conducted from it by means of carbon brushes.
