DX450 (RED-D-ARC) A-1 INST ALLA TION A-1 1. Output rating in watts is equivalent to volt-amperes at unity power factor. Output voltage is within ± 10% at all loads up to rated capacity. When welding, available auxiliary power will be reduced. * To Top of enclosure, add 10.
A-2 INST ALLA TION DX450 (RED-D-ARC) A-2 SAFETY PRECAUTIONS Only qualified personnel should install, use, or service this equipment. Do not attempt to use this equipment until you have thoroughly read the engine manufacturer’s manual supplied with your welder.
A-3 INST ALLA TION DX450 (RED-D-ARC) A-3 HIGH ALTITUDE OPERATION At higher altitudes, output derating may be necessary. For maximum rating, derate the machine 1.0% for every 2000 ft. (610m) up to 6000 ft. (1828m) and 2.0% for every 2000 ft. (610m) over 6000 ft.
The standard muffler included with this welder does not qualify as a spark arrester. When required by local regulations, a suitable spark arrester, such as the K903-1 must be installed and properly maintained. An incorrect spark arrestor may lead to damage to the engine or adversely affect performance.
A-5 INST ALLA TION A-5 ELECTRICAL CONNECTIONS MACHINE GROUNDING Because this portable engine driven welder creates its own power, it is not necessary to connect its frame to an earth ground, unless the machine is connected to premises wiring (home, shop, etc.

D-3 MAINTENANCE D-3 DX450 (RED-D-ARC) Unfasten or unlatch the s ervice cover . Because the filter fits tightly over the outlet tube to create the critical seal, there will be some initial resistance, similar to breaking the seal on a jar . Gently move the end of the filter back and forth to break the seal then rotate while pulling straight out.
D-4 MAINTENANCE D-4 COOLING SYSTEM HOT COOLANT can burn skin. • Do not remove cap if radiator is hot. ------------------------------------------------------------------------ Check the coolant level by observing the level in the radiator and recovery bottle.
D-5 MAINTENANCE D-5 FUEL FIL TER 1 . Check the fuel filter and fuel pre-filter for water accumulation or sediment. 2. Replace the fuel filter if it is found with excessive water accumulation or sediment. Empty fuel pre-fil- ter. ENGINE ADJUSTMENT Adjustments to the engine are to be made only by a Service Center or an authorized Field Service Shop.
D-6 MAINTENANCE D-6 DX450 (RED-D-ARC) GFCI MODULE TESTING AND RESETTING PROCEDURE The GFCI module should be properly tested at least once every month or whenever it is tripped.
