ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. 3.b.
WELDING and CUTTING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding materials from welding can easily go through small cracks and openings to adjacent areas.

GENERAL DESCRIPTION The CLASSIC ® 300D KUBOTA is a heavy duty, engine driven, DC arc welding power source, capable of providing constant current output for stick welding or DC TIG welding. This welder is wound with all cop- per coils, rated at 300 amps/32 Volts, and provides other Classic features such as improved door latches and stainless hinges.
PRE-OPERATION INSTALLATION WARNING Do not attempt to use this equipment until you have thoroughly read the engine manufacturerʼs manual sup- plied with your welder. It includes important safety pre- cautions, detailed engine starting, operating and main- tenance instructions, and parts lists. ------------------------------------------------------------------------ ELECTRIC SHOCK can kill.
TRAILER (See Optional Features) If the user adapts a non-Lincoln trailer, the user must assume responsibility that the method of attachment and usage does not result in a safety hazard nor dam- age the welding equipment. Some of the factors to be considered are as follows: 1.
Battery Charging WARNING GASES FROM BATTERY can explode. • Keep sparks, flame and cigarettes away. BATTERY ACID can burn eyes and skin. • Wear gloves and eye protection and be careful when boosting, charging or working near battery. To prevent EXPLOSION when: a) Installing a new battery - disconnect the negative cable from the old battery first and connect the negative cable to the new battery...
MAINTE- NANCE section of this manual. ENGINE BREAK-IN Lincoln Electric selects high quality, heavy-duty indus- trial engines for the portable welding machines we offer. While it is normal to see a small amount of...
Larger machines with a capacity of 350 amperes and higher, which are operated at low or no-load condi- tions for extended periods of time are especially sus- ceptible to the conditions described above. To accomplish successful engine break-in, most diesel- powered equipment needs only to be run at a reason- ably heavy load within the rating of the welder for some period of time during the engineʼs early life.
IDLER OPERATION Start the engine with the “Idler” switch in the “High” position. Allow it to run at high idle speed for several minutes to warm the engine. See Specifications for operating speeds. The idler is controlled by the “Idler” toggle switch on the welder control panel.
The use of an arc welder for pipe thawing is not approved by the CSA, nor is it recommended or supported by Lincoln Electric. ------------------------------------------------------------------------ Power Plug Kit (K802D) - A power plug kit for the auxiliary power receptacles is available.
WIRE FEED OPTIONS Wire Feed Module (K623-1) - Provides constant voltage (CV) output with improved arc stability for Innershield welding. Excellent for MIG welding. Recommended wire feeders are the LN-7, LN-23P and LN-25. (Factory installed on the K1643-6). LN-25 Wire Feeder (K449)-Portable CC/CV unit for flux-cored and MIG welding.
MAINTENANCE WARNING Have qualified personnel do the maintenance work. Turn the engine off before working inside the machine. In some cases, it may be neces- sary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is com- plete.
Replace brushes when they wear within 1/4”(3.5mm) of the pigtail. A complete set of replacement brushes should be kept on hand. Lincoln brushes have a curved face to fit the commutator. Have an experi- enced maintenance man seat these brushes by lightly stoning the commutator as the armature rotates at full speed until contact is made across the full face of the brushes.
