SAFETY PRECAUTIONS

Read entire installation section before starting installation.

WARNING

ELECTRIC SHOCK can kill.

•Only qualified personnel should perform this installation.

•Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.

•Do not touch electrically hot parts.

•Always connect the Precision TIG 375 grounding screw (behind the reconnect panel cover located near the back of the left case side) to a good electrical earth ground.

•Always connect the Precision TIG 375 to a power supply grounded in accordance with the National Electrical Code and all local codes.

SELECT SUITABLE LOCATION

Place the welder where clean cooling air can freely cir- culate in through the top rear vents and out through the bottom rear vents. Dirt, dust or any foreign material that can be drawn into the welder should be kept at a minimum. Failure to observe these precautions can result in excessive operating temperatures and nui- sance trips.

GRINDING

Do not direct grinding particles towards the welder. An abundance of conductive material can cause mainte- nance problems.

STACKING

The Precision TIG 375's cannot be stacked .

UNDERCARRIAGE LIFTING AND MOVING

When the Precision TIG 375 is purchased as a weld- ing package, or used with any of the available Undercarriage optional accessories, proper installation makes the Precision TIG 375 lift bale nonfunctional. Do not attempt to lift the power source with an under- carriage attached. The undercarriage is designed for hand moving only; mechanized movement can lead to personal injury and/or damage to the Precision TIG 375.

TILTING

Each machine must be placed on a secure, level sur- face, either directly or on a recommended undercar- riage. The machine may topple over if this precaution is not followed.

ENVIRONMENTAL RATING

Precision TIG 375 power sources carry an IP21S Environmental rating. They are rated for use in damp, dirty rain-sheltered environments.

MACHINE GROUNDING AND HIGH FRE- QUENCY INTERFERENCE PROTECTION

The frame of the welder must be grounded. A ground screw marked with the symbol is located on the input connection panel (Figure A.1) for this purpose. See your local and nation- al electrical codes for proper grounding methods.

The spark gap oscillator in the high frequency genera- tor, being similar to a radio transmitter, can be blamed for many radio, TV and electronic equipment interfer- ence problems. These problems may be the result of radiated interference. Proper grounding methods can reduce or eliminate radiated interference.

The Precision TIG 375 has been field tested under rec- ommended installation conditions and has been found to comply with F.C.C. allowable radiation limits. This welder has also been found to comply with NEMA stan- dards for high frequency stabilized power sources.

Radiated interference can develop in the following four ways:

•Direct interference radiated from the welder.

•Direct interference radiated from the welding leads.

•Direct interference radiated from feedback into the power lines.

•Interference from re-radiation of "pickup" by ungrounded metallic objects.

Keeping these contributing factors in mind, installing the equipment per the following instructions should minimize problems.

1.Keep the welder power supply lines as short as possible. Input leads within 50 feet (15.2 m) of the welder should be enclosed in rigid metallic conduit or equivalent shielding. There must be good electri- cal contact between this conduit and the welder. Both ends of the conduit must be connected to a driven ground and the entire length must be contin- uous.

2.Keep the work and electrode leads as short as pos- sible and as close together as possible. Lengths should not exceed 25 feet (7.6 m). Tape the leads together when practical.
