BOLT 8T6871 - Caterpillar

Introduction
The 1U-6161 Wire Feeder is excellent in field applications using aluminum, flux core, and solid wire. This wire feeder is also recommended for use with the 1U-9600 Bore Welder. The unit is designed for high production applications, where portability is important. This unit is small and very versatile with a 450 amp capability.Structurally, the unit is designed to withstand abuse in rugged field environments and continuous applications. A heavy duty contactor, with replaceable long-life contacts, make this unit perfect for high-duty cycle applications. It can be hooked up to any one of several power sources in a matter of minutes. The wire feeder comes complete with all the necessary parts-ready to begin welding.
1U-6161 Wire FeederThe wire feeder operates when supplied by a welding power source such as a constant DC voltage or a stick welder with constant amperage. The wire feeder requires a direct connection from the power source to the input of the unit. The wire feeder functions in both reverse polarity and straight polarity by simply moving a selector switch. The 1U-6161 Wire Feeder does not require 110 or 220 volts to operate; it operates directly off of the positive or negative lead of power source.Features
* Cabinet size allows 100 to 300 mm (4 to 12 in) diameter wire spools and 6 to 13 kg (14 to 30 lb) coils.* Hinged doors provide quick and easy maintenance.* A four-way flowmeter gives readings on carbon dioxide, argon, helium, and oxygen.* Increases safety by eliminating 115 Volt AC at the wire feeder.* Decreases downtime and maintenance by eliminating costly multiconductor control cables.* Operates entirely on ARC voltage utilizing only a single weld power supply cable.* The weld wire is electrically nonconductive until gun trigger is actuated.* Demonstrates superior performance when used with any constant current, constant potential, constant voltage, variable voltage, multiple operator grid systems and any DC gas drive power source.* Ease of controlling weld metal decreases training time for the new welders, provides higher quality and increased production from experienced welders.* Voltage remains constant, not effected by wire stick out variations and movement.* Offers wire speeds from 0.5 to 16 meters per minute (20 to 650 inches per minute) with wire sizes from 0.76 to 2.38 mm (.030 to 3/32 in).Function Of Wire Feeder Components Front View

(1) Cold wire inch switch. (2) On/Off switch. (3) DC voltmeter. (4) Wire speed/amperage meter. (5) Three-position knob. (6) Wire speed controller. (7) Input jack. (8) Weld gun connector.1. Cold Wire Inch Switch. Used to run wire through the gun. The wire can pass through to the weld gun (without power) eliminating accidental arcing of the weld wire.2. On/Off Switch. Used to power up unit.3. D.C. Voltmeter. Indicates voltage being supplied to the wire feeder. It also shows the voltage going to the wire during welding.4. Wire Speed/Amperage Meter. This meter provides both wire speed and amperage readings. If control knob (5) is in the "AMPS" position, the meter indicates amperage of the welding process. When in
