INSTALLATION
Read entire installation section before starting installation.
Safety Precautions
WARNING
ELECTRIC SHOCK can kill.
•Only qualified personnel should perform this installation.
•Turn the Power Source input power OFF at the disconnect switch or stop the engine before attempting to connect the TIG Module
•Do not touch electrically hot parts.
Users should familiarize themselves with Figure 8, Rear Connections, in the Operating Section of this manual before proceeding.
LOCATION
The TIG Module can be mounted in or carried to any convenient location. It is designed to be portable. If placed on the roof of engine welders, it must be mounted securely. A Docking Kit option is available for this purpose. See the Accessories section.
ENVIRONMENTAL PROTECTION
This accessory qualifies for an IP23 rating. It is suited for use in damp, dirty and dusty locations. (In locations where there are large amounts of conductive metal or salt particles in the air, additional maintenance may be required.) It is protected against rainfall. Excessive moisture can, however, cause short term operational difficulties. Difficulties can occur with the spark gap; it may not “spark” when the unit is first turned on after prolonged exposure to moisture. Usually, allowing the unit to operate for 5 to 15 minutes will allow the spark gap to dry out, and return to normal operation.
HIGH FREQUENCY INTERFERENCE PROTECTION
Since the spark gap oscillator in the TIG Module is similar to a radio transmitter, improper installation can result in radio and TV interference or problems with nearby electronic equipment.
Radiated interference can develop in the following four ways:
1.Direct interference radiated from the welder and the TIG Module.
2.Direct interference radiated from the welding leads.
3.Direct interference radiated from feedback into the power lines.
4.Interference from reradiation of “pickup” by ungrounded metallic objects.
Keeping these contributing factors in mind, installing equipment per the following instructions should minimize problems.
1.Keep the power source input supply lines as short as possible and completely enclose them in rigid metallic conduit or equivalent shielding for a minimum distance of 50 feet (15.2 m). There should be good electrical contact between this conduit and the welder. Both ends of the conduit should be connected to a driven ground and the entire length should be continuous.
2.Keep the work and electrode leads as short as possible and as close together as possible. Lengths should not exceed 25 feet (7.6 m). Tape the leads together when practical.
3.Be sure the torch and work cable rubber coverings are free of cuts and cracks that allow high frequency leakage. Cables with high natural rubber content, such as Lincoln
4.Keep the torch in good repair and all connections tight to reduce high frequency leakage.
5.The work terminal must be connected to a ground within ten feet of the welder, using one of the following methods:
a)A metal underground water pipe in direct contact with the earth for ten feet or more.
b)A 3/4” (19 mm) galvanized pipe or conduit or a 5/8” (16 mm) solid galvanized iron or steel or copper rod driven at least eight feet into the ground.
The ground should be securely made and the grounding cable should be as short as possible using cable of the same size as the work cable, or larger. Grounding to the building frame electrical conduit or a long pipe system can result in reradiation, effectively making these members radiating antennas.
NOTE: The welder frame MUST also be grounded. The work terminal ground does not ground the welder frame.
