230V INPUT

The equipment is provided with a 230/115V cable, 6.6ft.(2m) in length with a 230V 6-50P attachment plug.

The Invertec® V205-T AC/DC™ performs best when connected to 230VAC inputs. This input allows full out- put of the machine (200 amps).

115V INPUT

A suitable 115V attachment plug must be installed on the power cord to use the V205-T AC/DC™ with a 115V input supply. The rated output of the V205-T AC/DC™ is available when connected to a 30A branch circuit. When connected to a branch circuit with lower amp rating, lower welding current 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 cir- cuit and fuse/circuit breaker characteristics will affect the available output. Do not exceed these welding con- ditions:

15A branch circuit

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

20A branch circuit

10% duty cycle Stick: 90A TIG: 130A

ATTACHMENT PLUG INSTALLATION

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 ter- minal clamp with green screw.

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.

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

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

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.

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

ENGINE DRIVEN GENERATOR

The Invertec® V205-T AC/DC™ can be operated on engine driven generators as long as the 230 volt auxil- iary meets the following conditions:

•The AC waveform peak voltage is below 400 volts.

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

The following Lincoln engine drives meet these condi- tions when run in the high idle mode:

•Ranger 250,305

•Commander 300, 400, & 500

Some engine drives do not meet these conditions (e.g. Miller Bobcats, etc). Operation of the Invertec® V205- T AC/DC™ is not recommended on engine drives not conforming to these conditions. Such drives may deliv- er unacceptably high voltage levels to the Invertec® V205-T AC/DC™ power source.
