0 AC voltage is present at the AC receptacles at all times regardless of the position of the AC/DC (WELD) selector. However, when this selector is in the DC (WELD) position, the AC voltage is unregulated. Under no circumstances should any type of electrical appliance be plugged into any of the AC receptacles when the selector is in the DC (WELD) posi- tion. 5. Set the current adjuster knob to the proper current level for the job being done. WELDING CABLE SELECTION When choosing welding cable, it is best to allow a comfortable safety margin. The cable’s length, gauge (diameter), and material all combine to determine how much current it can safely carry. The table below gives the current carry- ing capacity of various lengths and gauges of standard copper welding cable. I I I LENGTH IN FEET* I CABLE GAUGE CAB L,E DIA. O-50 FT. 50-100 FT. loo-250 FT. CURRENT CAPACITY AMPERES 1 .644 250 200 170 2 .604 200 195 150 * Lengths given are for the combined length of the positive and negative cables. CAUTION: An undersize cable will offer unacceptably high resistance to current flow from the welder. This will lead to poor quality welds and will shorten the life of the generator/welder. OPERATING RATE The welder should not be operated continuously at high current settings. Th,e proportion of welding time to “rest” time is called the Operating Rate. For example: The welder’s Operating Rate at 1.10 Amps is 70%. This means that in a given 10 minutes period actual welding can be performed for a total of 7 minutes. Use the table below to determine the Operating Rate for other current settings. Current 170A 150A 130A IlOA Below 90A Rate 20% 30% 50% 70% 100% 6. STOPPING THE ENGINE 1. Turn the appliance switch off and the AC circuit breaker off. ClRCUli BREAKER 2. Stop welding or cutting. Turn the engine switch off. 3. Turn the fuel valve off. 22 7. MAINTENANCE The purpose of the maintenance and adjustment schedule is to keep the gen- erator/welder in the best operating condition. Inspect or service as scheduled in the table on the next page. m Shut off the engine before performing any maintenance. If the engine must be run, make sure the area is well ventilated. The exhaust con- tains poisonous carbon monoxide gas. CAUTION: Use only genuine HONDA parts or their equivalent. The use of replacement parts which are not of equivalent quality may damage the gen- erator/welder.

(2): These items should be serviced by an authorized Honda dealer, unless the owner has the proper tools and is mechanically proficient. See the Honda Shop Manual. Tool kit The tools supplied are necessary for performing some periodic maintenance, simple adjustments and repairs. Always keep the tool kit with the generator/welder. Changing oil Drain the oil while the engine is still warm to assure rapid and complete drain- ing. 1. Remove the drain plug and filler cap, and drain the oil. Retighten the drain plug securely. 2. Refill with the recommended oil (see page 7) and check the level. DRAIN I L FILLER CAP Air cleaner service A dirty air cleaner will restrict air flow to the carburetor. To prevent carbure, tor malfunction, service the air cleaner regularly. Service more frequently when operating the generator/welder in extremely dusty areas. -N ever use gasoline or low flash point solvents for cleaning the air cleaner element. A fire or explosion could result. CAUTION: Never run the engine without the air cleaner. Rapid engine wear will result. 1. Unsnap the clips, remove the air cleaner cover and remove the element. 1 EMENT 2. Wash the element in a non-flammable or high flash point solvent and allow it to dry. 3. Soak the element in clean engine oil and squeeze out the excess oil. 4. Reinstall the air cleaner element and the cover. t ELEMENT Sediment cup service The sediment cup prevents dirt or water which may be in the fuel tank from entering the carburetor. If the engine has not been run for a long time, the cup should be cleaned. 1. Turn the fuel valve OFF. Remove the sediment cup. 2. Clean the cup thoroughly. 3. Reassemble. Do not’ damage the rubber gasket. B After installing the sediment cup, check for fuel leaks and make sure the area is dry before starting the engine.
