SAFETY PRECAUTIONS
WARNING
Do not attempt to use this equipment until you have thoroughly read the engine manufacturer’s manual supplied with your welder. It includes important safety precautions, detailed engine starting, operating and maintenance instructions,
and parts lists.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or electrode with skin or wet clothing.
•Insulate yourself from work and ground
•Always wear dry insulating gloves.
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or vent exhaust outside.
MOVING PARTS can injure.
•Do not operate with doors open or guards off.
• Stop engine before servicing.
•Keep away from moving parts.
See additional warning information at the
front of this operator’s manual.
GENERAL DESCRIPTION
The Classic™ II is a heavy duty engine driven DC arc welding power source capable of providing constant current output for stick welding or DC TIG welding. The Classic II is wound with all copper coils and is configured in a new shorter case with no exciter stick- out and setup for one side service. With the addition of the optional Wire Feed Module on models
This unit uses the Deutz
When an engine is started for the first time, some of the oil will be needed to fill the passages of the lubricating system. Therefore, on initial starting, run the engine for about five minutes and then stop the engine and recheck the oil. If the level is down, fill to the full mark again. The engine controls were properly set at the factory and should require no adjusting when received.
At the end of each day’s welding, drain accumulated dirt and water from the sediment bowl under the fuel tank and from the fuel filter per instructions in the engine manufacturer’s operating manual. Refill the fuel tank to minimize moisture condensation in the tank. Also, running out of fuel tends to draw dirt into the fuel system. Check the crankcase oil level.
In diesel engines, if the fuel supply is cut off or runs out while the fuel pump is operating, air may be entrapped in the fuel distribution system. If this happens, bleeding of the fuel system should not be required since the Deutz
Cold Weather Starting
Follow the instructions on the nameplate and in the engine manual shipped with the welder. With a fully charged battery and the proper weight oil, the engine should start satisfactorily even down to about 0°F.
If the engine must be frequently started below 10°F, it may be desir- able to install the optional ether starter kit. Installation and operating instructions are included in the kit. Use ether starting only when required because excessive use shortens engine life.
It is important that the Engine Manufacturer’s recommendations for oil and fuel are followed to obtain satisfactory cold weather perfor- mance. Consult the engine manual.
Duty Cycle
The NEMA output rating of the Classic II is 250 amperes at 30(1) arc volts on a 60% duty cycle (consult SPECIFICATIONS for alternate ratings). Duty cycle is based on a ten minute period; thus, the welder can be loaded at rated output for six minutes out of every ten minute period.
(1)The Lincoln “plus output” rating at 60% duty cycle is 250 amperes at 40 volts.
Starting the Deutz F3L-1011F Engine
To start the engine, place the “IDLER” switch in the “HIGH” position, the “IGNITION” switch in the “ON” position and then press the “START” button. When the engine starts running, observe the oil pressure. If no pressure shows within 30 seconds, stop the engine and consult the engine operating manual. To stop the engine, place the “IGNITION” switch in the “OFF” position. If the engine protection warning light comes on during cranking or after start up, the “igni- tion” switch must be placed in the “OFF” position to reset the engine protection system.
Control of Welding Current
CAUTION
DO NOT TURN THE “CURRENT RANGE SELECTOR” WHILE WELDING because the current may arc between the contacts and damage the switch.
The “Current Range Selector” provides five overlapping current ranges. The “Fine Current Adjustment” adjusts the current from min- imum to maximum within each range. Open circuit voltage is also controlled by the “Fine Current Adjustment” permitting control of the arc characteristics.
