The arc welding machine prime power source shal
12、l be a standard internal combustion engine of current commercial design and with sufficient horsepower to operate the welding power source at its maximum rated load and duty cycle. 3.3.1 Type I and II engines shall be 4-cycle gasoline engines designed to run on either leaded or unleaded gasoline wit
13、h an octane rating of at least 83. 3.3.2 Type III and IV engines shall be either 2-cycle or 4-cycle diesel engines designed to run on No. 2 grade diesel fuel. 3.3.3 The arc welding machines shall contain a 12-volt electrical starting system with an automatic battery recharging capability. When speci
14、fied, Type I machines may contain a manually operated starting mechanism rather than an electrical starting system. 3.3.4 Type II, III, and IV engines shall be equipped with a low oil pressure shutdown device. 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license fro
15、m IHS-,-,-A-A-59454 3.3.5 The welding machine fuel storage capacity when the engine is operated at maximum load and at rated duty cycle shall be sufficient to operate Type I machines for at least three hours, Type II machines for at least six hours, and Type III and IV machines for at least eight ho
16、urs. 3.4 Output power source. The welding machine electrical power source shall meet the requirements of NEMA EW- 1 and shall produce constant-current, self-regulating output power with a drooping volt-ampere characteristic. 3.4.1 Type II, III, and IV welding machines shall be provided with a switch
17、 to reverse the polarity of the welding current. 3.4.2 The welding current output shall be manually regulated in two steps. A coarse control shall select convenient output current increments through the entire range of the machine. A fine control shall then provide stepless adjustments within the ra
18、nge of each selected increment. 3.4.3 The machine shall contain an auxiliary power system meeting the requirements of NEMA EW-1. The auxiliary system shall include a 115-volt AC duplex receptacle circuit for lights and power tools. When specified, a 230-volt AC circuit with a designated kilowatt cap
19、acity shall also be provided (see 7.5(d). Auxiliary circuits shall include automatic overload protection device s. 3.5 Cables. The welding cables and electrode holders shall be as specified in the contract (see 7.5(e). 3.6 Nameplate. A nameplate conforming to the requirements of NEMA EW-1 shall be s
20、ecurely attached to the machine. Unless otherwise specified (7.5(f), the nameplate shall display the following information: a. Nomenclature b. Manufacturers t ype designation and/or identification number d. Maximum open circuit voltage e. Rated load volts f. Rated load amperes g. Duty cycle at rated
21、 load h. Maximum rated speed of generator in rpm at no load i. Related frequency of power supply j. Number of phases of power supply k. Rated input voltage of power supply 1.
