Safety Precautions

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 Square Wave TIG 275 grounding screw (located on the right rear corner of the base) to a good electrical earth ground.

•Always connect the Square Wave TIG 275 to a power supply grounded per the National Electrical Code and any local codes.

SELECT SUITABLE LOCATION

Place the welder where clean cooling air can freely cir- culate in through the rear louvers and out through the side louvers. 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 nuisance trips.

Square Wave TIG 275’s cannot be stacked.

LIFTING AND MOVING

The Square Wave TIG 275 should be lifted with a hoist. (It weighs approximately 330 lbs./150 kg.) An optional undercarriage is available to easily move the unit. Refer to the Accessories section of this manual. The Square Wave TIG 275 is designed to be used with a K932-1 Undercarriage. Complete installation instructions are included with the K932-1 Undercarriage. When the undercarriage is properly installed, the Square Wave TIG 275 lift bale is nonfunctional. Do not attempt to lift the power source with the undercarriage attached. The undercarriage is designed for hand moving only; mechanized towing can lead to personal injury and/or damage to the Square Wave TIG 275.

TILTING

Each machine must be placed on a secure, level surface, either directly or on a recommended undercarriage. The machine may topple over if this procedure is not followed.

ENVIRONMENTAL RATING

The Square Wave TIG 275 power source carries an IP21 environmental rating. It may be used in normal industrial and commercial environments. It is 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 at the right rear corner of the base for this purpose. See your local and nation- al electrical codes for proper grounding methods.

The spark gap oscillator in the high frequency generator, being similar to a radio transmitter, can be blamed for many radio, TV and electronic equipment interference problems. These prob- lems may be the result of radiated interference. Proper ground- ing methods can reduce or eliminate radiated interference.

The Square Wave TIG 275 has been field tested under rec- ommended installation conditions and has been found to com- ply with F.C.C. allowable radiation limits. A certificate (S14929) is being sent with each welder for customer convenience. If he desires or is required to obtain certification of compliance with F.C.C.RF Energy Radiation Limits, this certificate can be used. It is the customer's responsibility to obtain this certification. This welder has also been found to comply with NEMA standards for high frequency stabilized power sources.

Radiated interference can develop in the following four ways:

1.Direct interference radiated from the welder.

2.Direct interference radiated from the welding leads.

3.Direct interference radiated from feedback into the power lines.

4.Interference from re-radiation of “pickup” by ungrounded metallic objects.

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

1.Keep the welder power supply lines as short as pos- sible and enclose as much of them as possible in rigid metallic conduit or equivalent shielding for a distance of 50 feet (15.2m). There should be good electrical contact between this conduit and the welder case ground. Both ends of the conduit should be connected to a driven ground and the entire length should be continuous.
