Read the section on electromagnetic compatibility in this manual.

• Do not operate in areas with an ambient temperature greater than 40°C.

Input Supply Connection

Check the input voltage, phase, and frequency supplied to this machine before turning it on. The allowable input voltage is indicated in the technical specification section of this manual and on the rating plate of the machine.

Verify the connection of grounding wires from the machine to the input source.

Make sure the amount of power available from the input connection is adequate for normal operation of the machine. The necessary fuse and cable sizes are indicated in the technical specification section of this manual.

The V270-T AC/DC is machine is designed to operate on engine driven generators as long as the Vac auxiliary can supply adequate power as indicated in the technical specification section of this manual. The auxiliary supply of the generator must also meet the following conditions.

• The AC waveform peak voltage is below 620V.

• The AC waveform frequency is between 50 and 60

Hz.

• The RMS voltage of the AC waveform is always equal to 230/400Vac ±10%.

It is important to check these conditions because many engine driven generators produce high voltage spikes.

Operation of this machine on engine driven generators not conforming to these conditions is not recommended and may damage the machine.

Output Connections

A quick disconnect system using Twist-Mate cable plugs is used for the welding cable connections. Refer to the following sections for more information on connecting the machine for operation of stick welding (MMA) or TIG welding (GTAW).

Stick Welding (MMA)

First determine the proper electrode polarity for the electrode to be used. Consult the electrode data for this information. Then connect the output cables to the output terminals of the machine for the selected polarity.

For example, if DC(+) welding will be used then connect the electrode cable to the (+) terminal of the machine and the work clamp to the (-) terminal. Insert the connector with the key lining up with the keyway and rotate approximately ¼ turn clockwise. Do not over tighten.

For DC(-) welding switch the cable connections at the machine so that the electrode cable is connected to (-) and the work clamp is connected to (+).

TIG Welding (GTAW)

This machine does not include a TIG torch necessary for

TIG welding, but one may be purchased separately.

Refer to the accessories section for more information.

Connect the torch cable to the (-) terminal of the machine and the work clamp to the (+) terminal. Insert the connector with the key lining up with the keyway and rotate approximately ¼ turn clockwise. Do not over tighten.

User Interface Overview and Operation

Figure B.3

The V270-T AC/DC User interface consists of the following (Refer to Figure B.3):

1. Dynamic LCD Display

2. Status LED Lights

a) VRD On (Voltage Reduction Device) - If the voltage reduction device is enabled from the setup menu this green LED will illuminate when the open circuit voltage is present at the output terminals and held below the VRD threshold limit. If the VRD is disabled or the unit is welding, it will not illuminate.

b) General Alarm - Yellow LED which is lit when faults exist with the power source or optional cooler, such as over temperature, coolant blockage, etc.

c) Output On (No VRD) - This status light will illuminate red whenever the output in electrically hot and the voltage level is above the VRD threshold value.

3. 7-segment LED display (H)

4. Push button / Rotary Encoder

5. Mode Push buttons (A-D)

6. Push buttons (E, F)

e) Memory

Dynamic LCD Display

The Dynamic display is divided into several sections

(Refer to Figure B.4):

1. Supply attachment.

3. Connector: SERVICE purposes only.

l1: Power Switch.

• With "l1" in the "I"(ON) position, the welding machine is operational and there is voltage between the positive (+) and negative (-) Terminals in stick welding. In TIG, the welding process needs a trigger closure command at the remote control connection (Usually via an Arc Start Switch or Foot

Amptrol).

• The welder is connected to the supply even if the

"l1" (Power Switch) is in the "O" (Off) position, and therefore there are electrically live parts inside the power source. Carefully follow the instructions given in this manual.

Push button B: Trigger Modes

TIG Trigger Sequences

TIG welding can be done in either the 2-step or 4-step mode. The specific sequences of operation for these two trigger modes are explained below.

2-Step TIG Sequence

With the 2-step trigger mode and a TIG welding mode selected, the following welding sequence will occur.

Figure B.4c

A-4

1. Press and hold the TIG torch trigger to start the sequence. The machine will open the gas valve to start the flow of the shielding gas. After the preflow time, to purge air from the torch hose, the output of the machine is turned ON. At this time the arc is started according to the selected welding mode.

After the arc is started the output current will be increased at a controlled rate, or upslope time, until the Welding current is reached.

2. Release the TIG torch trigger to stop welding. The machine will now decrease the output current at a controlled rate, or downslope time, until the Crater current is reached and the output of the machine is turned OFF.

After the arc is turned OFF, the gas valve will remain open to continue the flow of the shielding gas to the hot electrode and work piece.

As shown above, it is possible to press and hold the TIG torch trigger a second time during downslope to end the downslope function and maintain the output current at the Crater current. When the TIG torch trigger is released the output will turn OFF and the postflow time will start. This operation, 2-step restart disabled, is the default setting from the factory.

4-Step Sequence

With the 4-step trigger mode and a TIG welding mode selected, the following welding sequence will occur.

1. Press and hold the TIG torch trigger to start the sequence. The machine will open the gas valve to start the flow of the shielding gas. After the preflow time, to purge air from the torch hose, the output of the machine is turned ON. At this time the arc is started according to the selected welding mode.

After the arc is started the output current will be at the Start current. This condition can be maintained as long or as short as necessary.

If the Start current is not necessary, do not hold the

TIG torch trigger as described at the beginning of this step. In this condition, the machine will pass from Step 1 to Step 2 when the arc is started.

2. Releasing the TIG torch trigger starts the upslope function. The output current will be increased at a controlled rate, or upslope time, until the Welding current is reached.

3. Press and hold the TIG torch trigger when the main part of the weld is complete. The machine will now decrease the output current at a controlled rate, or downslope time, until the Crater current is reached.

This Crater current can be maintained as long or as short as necessary.

This sequence has an automatic restart so welding will continue after this step. This operation, 4-step restart enabled, is the default setting from the factory. If the weld is completely finished, use the following sequence instead of step 3 described above.

3A. Quickly press and release the TIG torch trigger. The machine will now decrease the output current at a controlled rate, or downslope time, until the Crater current is reached and the output of the machine is turned OFF. After the arc is turned OFF the postflow time will start.

4. Release the TIG torch trigger. The output current will again increase to the Welding current, like in step 2, to continue welding. When the main part of the weld is complete go to step 3.

As shown here, after the TIG torch trigger is quickly pressed and released from step 3A, it is possible to press and hold the TIG torch trigger another time to end the downslope time and maintain the output current at the

Crater current. When the TIG torch trigger is released the output will again increase to the

Welding current, like in step 4, to continue welding.

When the main part of the weld is complete go to step 3.

A-5

As shown here, again after the TIG torch trigger is quickly pressed and released from step 3A, it is possible to quickly press and release the

TIG torch trigger a second time to end the downslope time and stop welding.

• Press and hold Memory Save Button (E) for 3 seconds to save to memory. The Memory location display indicator (D) will change to a reverse text indicating that the current parameters are the ones in the actively selected memory.

Recalling from Memory

• Press and hold the memory recall button (F) for 3 seconds until the memory location display indicator changes to reversed text indicating the stored parameters are actively recalled.

• When memory parameters are actively selected, the display indicator will remain reversed until a welding parameter is changed with the encoder knob or until the memory location button is pressed to scroll to a different memory location.

Local/Remote Operation

The V270-T AC/DC, when in TIG mode, will automatically sense when the machine has a remote device plugged into the 6 pin MS-type connector-like a remote pedant or a foot amptrol. If a remote device is plugged in, the machine will automatically function in remote mode. If no device is plugged in, the machine will function in local mode.

In remote mode, the operation of the machine is slightly different depending on whether the remote device is a foot amptrol or a remote pendant. To let the machine know what type of device is plugged in,the operator must select the appropriate device from the trigger mode button (See Trigger mode descriptions above for details on the difference). In stick mode the second button on the control panel selects local or remote operation manually. This is required so that the user does not need to detach a foot amptrol to use the machine in

STICK mode.

Figure B.7

Rotating the encoder knob will scroll through the setup parameters shown in Table B.4. Selected parameters are changed in one of two ways:

For parameters like background current (shown in Figure

B.7a) the change is made by the mode push button. In this example you can toggle between setting background current as either a % or as absolute amperage. Other parameters like selectable wave shape (shown in Figure

B.7b) are changed by depressing the encoder knob until the parameter is flashing. Rotating the knob changes the parameter and then the change is saved by pressing the encoder knob again. Once all changes are made you can exitand save by pressing the exit icon button or you can exit the set up menu without saving your changes by depressing the hooked arrow button.
