OPERATION
PRODUCT DESCRIPTION
The TIG Module is an accessory for constant current power sources. It provides high frequency and shielding gas control for AC and DC GTAW (TIG) welding applications, and easy connection of Amptrol remote controls to power sources having remote control capability. It also provides contactor control of the welding current, always allowing the operator to make and break the arc with an Arc Start Switch or Amptrol remote control. A contactor option must be used for power sources which do not have a
The
RECOMMENDED PROCESSES AND EQUIPMENT
Recommended for TIG welding with AC or AC/DC constant current welding power sources rated 250 amps or higher. This includes transformer, transformer/rectifier and engine driven power sources with constant current output. For a listing of machines that the TIG Module can be used with, see Installation Section.
Fixed preflow timer for purging the weld area before an arc is struck. Preflow timer is automatically bypassed if a new weld is started during the Afterflow time; this allows quick tacking or spot welding, without the need to wait for the preflow time.
Design Features
Compact case is designed for easy carrying, complete with handle.
Case has rubber feet which provide cushioning and skid resistance when used as a portable unit.
Input studs, output studs, valve fittings and cable receptacles are located under a protective door. Door has a stainless steel hinge to resist corrosion.
Modular construction makes for easy servicing. All control and timer functions are contained on one printed circuit board.
The case was designed to complement the Ranger power source line, particularly the Ranger 8 and Ranger 9.
High frequency bypass is built into the TIG Module.
No work sense lead is required (as it was on the K799
No power source matching switch is required.
DESIGN SUMMARY
Operational Features and Controls
Wide input voltage range of 60 to 130 volts AC allows operation on Ranger power sources.
Power On/Off switch with Pilot Light.
High Frequency switch allows selection of Continuous, Start Only, or Off.
Contactor control by an Arc Start Switch or Amptrol (optional Contactor Kit required with certain power sources).
Afterflow Timer allows adjustable cooling period for gas and water (optional) flow after the weld is stopped.
Current Control functions as an adjustable limit control when using a remotely controllable power source. Allows operator to adjust welding current at the TIG module, instead of at the power source. Also allows Hand or Foot Amptrol control range to be narrowed, for better current control capability.
Welding Capability
The TIG Module is designed for arc starting in manual GTAW (TIG) applications. Application to automated GTAW equipment may be satisfactory also. It is the user’s responsibility to investigate and resolve issues regarding interfacing and operating with automated GTAW equipment.
