The Invertec V160-T is recommended for use on an individual branch circuit.

115V INPUT

The rated output of the V160-T is available when con- nected to a 30A branch circuit. When connected to a branch circuit with lower ampacity, lower welding cur- rent and duty cycle must be used. An output guide is provided below. The values are approximate and must be adjusted downward if the fuse or circuit breaker trips off. Other loads on the circuit and fuse/circuit breaker characteristics will affect the available output. Do not exceed these welding conditions:

15A plug on a 15A branch

10% duty cycle Stick: 65A TIG: 95A

15A plug on a 20A branch

10% duty cycle Stick: 75A TIG: 105A

20A plug on a 20A branch

10% duty cycle Stick: 85A TIG: 120A

The Invertec V160-T is provided with a 115/230V cable, 6.6ft.(2m) in length, with a 15Amp 5-15P plug molded onto the cord.

The V160-T is supplied with an additional 20A plug that can replace the 15A plug to achieve higher out- put. To install the supplied 20A plug:

Connect the white (neutral) wire under terminal clamp with silver screw, and black (hot) wire under terminal clamp with brass screw. Connect green wire under terminal clamp with green screw.

ARFU (AUTO-RESTORE FUSE)

The dual input voltage machine is provided with an ARFU device. It only operates when the input is con- nected to an 115V supply and protects from input over current conditions.

NOTE: The ARFU replaces a fuse (F2) that was used in older V160’s.

WARNING

•Failure to wire as instructed may cause personal injury or damage to equipment. To be installed or

checked by an electrician or qualified person only.

---------------------------------------------------------------------------

230V INPUT

To achieve the full output capacity of the V160-T, 230VAC inputs should be used. The change over is accomplished by replacing the 115VAC plug with a 30 Amp 230VAC plug (NEMA 6-30P).

ATTACHMENT PLUG

In all cases, the green or green/yellow grounding wire must be connected to the grounding pin of the plug, usu- ally identified by a green screw.

All attachment plugs must comply with the Standard for Attachment Plugs and Receptacles, UL498.

The product is considered acceptable for use only when an attachment plug as specified is properly attached to the supply cord.

The Invertec V160-T will auto reconnect to either 115V or 230V supplies.

ENGINE DRIVEN GENERATOR

For use on engine drives, keep in mind the above input draw restrictions and the following precaution.

The Invertec V160-T can be operated on engine driv- en generators as long as the 230 volt auxiliary meets the following conditions:

•The AC waveform peak voltage is below 400 volts*.

•The AC waveform frequency is between 45 and 65Hz.

•The RMS voltage of the AC waveform is always greater than 208VAC *.

* for 115 VAC input divide these values in half.
