PRODUCT DESCRIPTION

ELECTRICAL INSTALLATION

The Invertec V300-I is a 300 amp arc welding power source that utilizes single or three phase input power to produce either constant voltage or constant current outputs. The V300-I is designed for 50/60 Hz supply systems. The welding response of the Invertec has been optimized for GMAW, SMAW, TIG and FCAW processes. It is designed to be used with the LN-25 and LN-7 semiautomatic wire feeders.

WARNING

1.The Invertec should be connected only by a quali- fied electrician. Installation should be made in accordance with the U.S. National Electrical Code, all local codes and the information detailed below.

2.When received from the factory, multiple voltage (200/220/380-415/440) machines are internally connected for 440 volt input.

ELECTRIC SHOCK can kill.

•Have an electrician install and ser- vice this equipment.

•Turn the input power off at the fuse box before working on equipment.

•Do not touch electrically hot parts.

LOCATION

The Invertec has been designed with many features to protect it from harsh environments. Even so, it is important that simple preventative measures are fol- lowed in order to assure long life and reliable opera- tion.

•The machine must be located where there is free cir- culation of clean air such that air movement into the sides and out the bottom and front will not be restricted. Dirt and dust that can be drawn into the machine should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown of the Invertec.

3.Single voltage, 575 VAC machines, can only be connected to 575 VAC. No internal reconnection for other input voltages is possible.

4.Initial 208 VAC and 230 VAC operation will require

avoltage panel setup, as will later reconnection back to 460 VAC:

a.Open the access panel on the right side of the machine.

b.For 208 or 230: Position the large switch to 200-230.

For 460: Position the large switch to 380-460.

c.Move the “A” lead to the appropriate terminal.

CAUTION: DO NOT CHANGE SWITCH POSITION WITH INPUT POWER APPLIED. MAJOR DAMAGE WILL RESULT.

•Keep machine dry. Shelter from rain and snow. Do not place on wet ground or in puddles.

CAUTION

DO NOT ATTEMPT TO POWER THIS UNIT FROM THE AUXILIARY POWER SUPPLY OF AN ENGINE WELDER.

•Special protection circuits may operate, causing loss of output.

•The supply from engine welders often has exces- sive voltage peaks because the voltage waveform is usually triangular shaped instead of sinusoidal.

•If voltage peaks from the engine welder are too high (380v on 230v setting), the input circuits of this machine protecting the filter capacitors, FETS and other components from damage will not be ener- gized.

RECONNECT PROCEDURE

1. BE SURE POWER SWITCH IS OFF.	. Disconnect input power before
	inspecting or servicing machine.
