7. Install the welder in a dry location where there is free circu lation of air in through the louvers in front and out through the louvers in the back of the case A location which mini mizes the amount of smoke and dirt drawn into the machine reduces the chance of dirt accumulation that can block air passages and cause overheating INPUT WIRING WARNING 9 Have an electrician install and service this equipment Turn the input power off at the fuse box before working on equipment Do not touch electrically hot ELECTRIC paris SHOCK Failure to fuse the input lines per the specifications in this manual will constitute customer abuse and void the warranty Have a qualified electrician make the complete input con nection in accordance with the National Electrical Code all local codes and the connection diagram located inside the machine Be sure the voltage phase and frequency of the input power is as specified on the welder nameplate For most installations connect the AC 1500 to single phase power or to one phase of a three phase line Unbalanced line conditions can be easily avoided by properly balancing the AC 1500 with other machinery on the lines When installing two or four Scott connected AC 1500 machines for AC AC tandem arc welding three phase input power must be used The terminals for connections to pro vide an output phase angle less than or greater than the usual 90 phase angle are included on
8. Do not heat cut or weld tanks drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside They can cause an explosion even though they have been cleaned For information purchase Recommended Safe Practices for the Preparation for Welding and Cutting of Containers and Piping That Have Held Hazardous Substances AWS F4 1 from the American Welding Society see address above Vent hollow castings or containers before heating cutting or welding They may explode Sparks and spatter are thrown from the welding arc Wear oil free protective garments such as leather gloves heavy shirt cuffless trousers high shoes and a cap over your hair Wear ear plugs when welding out of position or in confined places Always wear safety glasses with side shields when in a welding area Connect the work cable to the work as close to the welding area as practical Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains crane cables or other alternate cir cuits This can create fire hazards or overheat lifting chains or cables until they fail Also see item 1 c Read and follow NFPA 51B Standard for Fire Prevention During Welding Cutting and Other Hot Work available from NFPA 1 Batterymarch Park PO
