SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

•Turn the input power OFF at the disconnect switch or fuse box and discharge input capacitors before working inside the equip- ment.

•Do not touch electrically hot parts or electrodes with your skin or wet clothing.

•Always connect the 55 grounding terminal (located on the side of the Case Back Assembly) to a good electrical earth ground.

•Always wear dry, insulating gloves.

•Turn the 55 Power Switch OFF when connecting power cord to input power.

Only qualified personnel should install, use, or ser- vice this equipment.

SELECT SUITABLE LOCATION

Place the Pro-Cut 55 where clean cool air can freely circulate in through the rear louvers and out through the front/bottom opening. Dirt, dust or any foreign material that can be drawn into the machine should be kept at a minimum. Failure to observe these precau- tions can result in excessive operating temperatures and nuisance shutdown of the machine.

A source of clean, dry air or nitrogen must be supplied to the Pro-Cut 55. Oil in the air is a severe problem and must be avoided. The supply pressure must be between 80 and 150 psi. The flow rate is approximate- ly 6.0 cfm (170 l/min.). Failure to observe these pre- cautions could result in excessive operating tempera- tures or damage to the torch.

STACKING

The Pro-Cut 55 cannot be stacked.

WARNING

FALLING EQUIPMENT can cause injury.

•Do not use the pull handle on the optional undercarriage, if installed, to lift the machine. This handle is not designed to support the full weight of the machine. Using it to lift the machine could cause per- sonal injury or damage to the machine.

•Either the front or rear handles or both may be used to lift or move the machine.

TILTING

The Pro-Cut 55 must be placed on a stable, level sur- face so it will not topple over.

HIGH FREQUENCY INTERFERENCE PROTECTION

The Pro-Cut 55 employs a touch start mechanism for arc initiation. This eliminates high frequency emissions from the machine as compared with spark gap and solid state type high frequency generators. Keep in mind, though, that these machines may be used in an environment where other high frequency generating machines are operating. By taking the following steps, you can minimize high frequency interference.

•Make sure the power supply chassis is connected to a good earth ground. The work terminal ground does NOT ground the machine frame.

•Keep the work ground clamp isolated from other work clamps that have high frequency.

•If the ground clamp cannot be isolated, then keep the clamp as far as possible from other work clamp con- nections.

•When the machine is enclosed in a metal building, several good earth driven electrical grounds around the periphery of the building are recommended.

Failure to observe these recommended installation procedures may cause improper function of the Pro- Cut or possibly even damage the control system or power supply components.
