SAFETY PRECAUTIONS Read this
entire installation section before you start installa-
tion.
WARNING
ELECTRIC SHOCK can kill.
•Only qualified personnel should per- form this installation.
•Turn the input power OFF at the
disconnect switch or fuse box before working on this equipment. Turn off the input power to any other equipment connected
to the welding system at the disconnect switch or fuse box before working on the equipment.
•Do not touch electrically hot parts.
•Always connect the Power Wave 455M/STT (CE) grounding lug (located inside the reconnect input access door) to a proper safety (Earth) ground.
SELECT SUITABLE LOCATION
Do not use Power Wave 455M/STT (CE) in outdoor environments. The Power Wave 455M/STT (CE) power source should not be subjected to falling water, nor should any parts of it be submerged in water. Doing so may cause improper operation as well as pose a safe- ty hazard. The best practice is to keep the machine in a dry, sheltered area.
Do not mount the Power Wave 455M/STT (CE) over combustible surfaces. Where there is a combustible surface directly under stationary or fixed electrical equipment, that surface shall be covered with a steel plate at least 1.6mm (.060") thick, which shall extend not less than 150mm (5.90") beyond the equipment on all sides.
Place the welder where clean cooling air can freely cir- culate in through the rear louvers and out through the case sides and bottom. Dirt, dust, or any foreign mate- rial that can be drawn into the welder should be kept at a minimum. Do not use air filters on the air intake because the air flow will be restricted. Failure to observe these precautions can result in excessive oper- ating temperatures and nuisance shutdowns.
Machines are equipped with F.A.N. (fan as needed) cir- cuitry. The fan runs whenever the output is enabled, whether under loaded or open circuit conditions. The fan also runs for a period of time (approximately 5 min- utes) after the output is disabled, to ensure all compo- nents are properly cooled.
If desired, the F.A.N. feature can be disabled (causing the fan to run whenever the power source is on). To disable F.A.N., connect leads 444 and X3A together at the output of the solid state fan control relay, located on the back of the Control PC board enclosure. (See Wiring Diagram)
LIFTING
Lift the machine by the lift bail only. The lift bail is designed to lift the power source only. Do not attempt to lift the Power Wave with accessories attached to it.
STACKING
Power Wave machines can be stacked to a maximum of 3 high.
WARNING
|
| • Lift only with equipment of |
|
| adequate lifting capacity. |
|
| • Be sure machine is stable |
|
| when lifting. |
|
| • Do not lift this machine using |
|
| lift bail if it is equipped with a |
|
| heavy accessory such as trail- |
|
| er or gas cylinder. |

cause injury. | • Do not operate machine while | |
|
| suspended from lift bail. |
Do not stack the Power Wave 455M/STT (CE) on top of any other machine.
The bottom machine must always be placed on a firm, secure, level surface. There is a danger of machines toppling over if this precaution is not taken.
MACHINE GROUNDING
The frame of the welder must be grounded. A ground
terminal marked with the symbol 
is located inside the reconnect/input access door for this purpose. See your local and national electrical codes for proper grounding methods.
HIGH FREQUENCY PROTECTION
Locate the Power Wave away from radio controlled machinery.
CAUTION
The normal operation of the Power Wave may adversely affect the operation of RF controlled equipment, which may result in bodily injury or damage to the equipment.
