2-1. DESCRIPTION

The TIG-Unit is an accessory package which enables the solid-state welding power source to provide Gas Tungsten Arc (GTAW) as well as Shielded Metal Arc Welding (SMAW) capability. This unit has high frequen- cy, polarity switch, gas and water valves, postflow timer, and 115 volts ac auxiliary power as standard, with me- ters, electroslope, pulser, preflow timer, and spot timer as options.

SECTION 3 – INSTALLATION OR RELOCATION

IMPORTANT: Read entire Section 8 on equipment that produces output in the radio frequency range, such as high-frequency starters, for site selection information and installation requirements before beginning the in- stallation procedures.

3-1. SITE SELECTION

Even though the TIG-Unit is an accessory package pro- viding Gas Tungsten Arc Welding (GTAW) capability for the solid-state welding power source, it is recom- mended that certain practices and procedures be fol- lowed to aid long life and efficient operation.

The TIG-Unit for 300 and 400 ampere welding power sources is convection-cooled. It does not have or need a fan to aide the cooling process. The TIG-Unit for 500 and 600 ampere welding power sources is fan-cooled. However, it is recommended that a suitable location be chosen to provide adequate airflow, not only for the welding power source, but for the TIG-Unit as well. See welding power source Owner’s Manual for proper instal- lation site information.

WARNING: RESTRICTED AIRFLOW can cause overheating and possible damage to internal parts.

•Maintain at least 18 inches (457 mm) of unrestricted space on all sides of unit, and keep underside free of obstructions.

•Do not place any filtering device over the in- take air passages that provide airflow for cooling this unit.

Warranty is void if any type of filtering device is used at intake air passages.

3-2. TRANSPORTING METHODS

This unit is equipped with a lifting eye for moving during installation. Weight capacity of the lifting eye only allows for supporting the unit and welding power source.

WARNING: ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

•Disconnect input power conductors from deenergized supply line BEFORE moving unit and welding power source.

FALLING EQUIPMENT can cause serious personal injury and equipment damage.

•Use lifting eye to lift unit only, NOT running gear, gas cylinders, or any other heavy accessories or devices.

•Use equipment of adequate capacity to lift the unit.

•If lifting or moving this unit with lift forks under the base, be sure that lift forks are long enough to extend beyond opposite side of the base.

Using lift forks too short can damage internal parts if tips of the lift forks penetrate the unit base, or may cause personal injury and/or equipment damage if unit falls off the lift forks.

3-3. COMPONENT INSTALLATION ON FACTORY INSTALLED UNITS (Figure 3-1)

WARNING: ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

•Shut down welding power source, and dis- connect input power employing lockout/tagging procedures before inspecting or installing.

Lockout/tagging procedures consist of pad- locking line disconnect switch in open position, removing fuses from fuse box, or shutting off and red-tagging circuit breaker or other discon- necting device.

The TIG-Unit was shipped installed on and wired into the welding power source. To prepare the TIG-Unit for operation, proceed as follows:

1.Open access door on lower front of TIG-Unit, re- move component bag, and route short intercon- necting cord (approximately 4 ft. or 1.2 m) with plug attached through access opening on left side of TIG-Unit. Connect plug to REMOTE 14 (Amperage And Contactor Control) receptacle on welding pow- er source; align keyway, insert plug, and rotate threaded collar clockwise.
