Duty cycle

The duty cycle of a welding machine is the percentage of time in a 10 minute cycle at which the welder can operate the machine at rated welding current.

Example: 35% duty cycle:

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.

Be sure that the machine is grounded.

Make sure the amount of power available from the input connection is adequate for normal operation of the machine. The fuse rating and cable sizes are both indicated in the "Technical Specification" section of this manual.

The machines: x V205 2V: (230 / 400Vac, single phase) x

V270: (400Vac, three phase) x V270 2V: (230 / 400Vac, three phase) x V405: (400Vac, three phase) are designed to operate on engine driven generators as long as the auxiliary can supply adequate voltage, frequency and power as indicated in the "Technical

Specification" section of this manual. The auxiliary supply of the generator must also meet the following conditions: x Vac peak voltage: below 410V (for 230Vac input) or

720V (for 400Vac input).

x Vac frequency: in the range of 50 and 60 Hertz.

x RMS voltage of the AC waveform:

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.

Most TIG welding is done with DC(-) polarity; 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.

For V205-S / V270-S / V405-S machine, connect the gas hose from the TIG torch to a gas regulator on the cylinder of gas to be used.

For V205-T / V270-T /

V405-T machine, connect the gas hose from the TIG torch to the gas connector (B) on the front of the machine. If necessary, an extra gas connector for the fitting on the front of the machine is included in the package. Next, connect the fitting on the back of the machine to a gas regulator on the cylinder of gas to be used. An input gas line and the required fittings are also included in the package.

Connect the TIG torch trigger to the trigger connector (A) on the front of the machine.

Remote Control Connection

Refer to the accessories section for a list of remote controls. If a remote control is used, it will be connected to the remote connector (C) on the front of the machine.

The machine will automatically detect the remote control, turn on the REMOTE LED, and switch to remote control mode. More information on this mode of operation will be given in the next section.

A-3

Controls and Operational Features

A. Power Switch: Controls the input power to the machine. Make sure the machine is properly connected to the input supply before turning the machine on.

B. Fan: The cooling fan will turn ON when the machine is turned ON and it will continue to run whenever the output of the machine is ON. If the output of the machine is OFF for more than five minutes, the fan will turn OFF.

This reduces the amount of dirt that is deposited inside the machine and reduces power consumption. Refer to the Output LED section below for more information about conditions when the output of the machine is ON.

If a Coolarc 20 is connected to a V205-T / V270-T, it will be turned ON and OFF with the operation of the fan. When Stick welding mode is used the Coolarc

20 will be OFF.

If a Coolarc 30 is connected to a V405-T, it will be turned ON and OFF with the operation of the fan.

When Stick welding mode is used the Coolarc 30 will be OFF.

C. Gas Inlet (V205-T / V270-T / V405-T only):

Connector for the TIG shielding gas. Use the supplied gas line and connector to connect the machine to the gas source. The gas source must have a pressure regulator and flow gage installed.

D. Mode Switch: This switch changes the welding modes of the machine. The V205-S / V270-S /

V405-S have two welding modes: Stick (SMAW) and Lift TIG (GTAW). The V205-T / V270-T / V405-

T machines have three welding modes: Stick

(SMAW), Lift TIG (GTAW) and HF TIG (GTAW).

When the mode switch is in the Stick position, the following welding features are enabled: x Hot Start: This is a temporary increase in the output current during the start of the stick welding process. This helps ignite the arc quickly and reliably. The amount of hot start can be adjusted on the V205-S / V270-S /

V405-S, refer to Hot Start, described below.

x Arc Force: This is a temporary increase in the output current during normal stick welding.

This temporary increase in output current is used to clear intermittent connections between the electrode and the weld puddle that occur during normal stick welding. The amount of arc force can be adjusted on the V205-S / V270-S /

V405-S, refer to Arc Force, described below.

x Anti-Sticking: This is a function which decreases the output current of the machine to a low level when the operator makes an error and sticks the electrode to the work piece. This decrease in current allows the operator to remove the electrode from the electrode holder without creating large sparks which can damage the electrode holder.

When the mode switch is in the Lift TIG position, the stick welding functions are disabled and the machine is ready for Lift TIG welding. Lift TIG is a method of starting a TIG weld by first pressing the

TIG torch electrode on the work piece in order to create a low current short circuit. Then, the electrode is lifted from the work piece to start the

TIG arc.

The last mode switch position, HF TIG, is only available on the V205-T / V270-T / V405-T. When the mode switch is in this position, the stick welding functions are disabled and the machine is ready for

HF TIG welding. During the HF TIG mode, the TIG arc is started by HF without pressing the electrode on the work piece. The HF used for starting the TIG arc will remain on for 6.5 seconds; if the arc is not started in this time limit, the trigger sequence must be restarted.

E. Power LED: This indicator will flash on and off when the machine is first turned on. After approximately 2 seconds it will stop flashing and remain on to signal that the machine is ready.

F. Thermal LED: This indicator will turn on when the machine is overheated and the output has been disabled. This normally occurs when the duty cycle

A-4 of the machine has been exceeded. Leave the machine on to allow the internal components to cool. When the indicator turns off, normal operation is again possible.

G. Remote LED: This indicator will turn on when a remote control is connected to the machine via the remote control connector. Using a remote control will change the function of the output current control, refer to the output current control section.

H. Output LED: This indicator turns on when the output of the machine is on. Both the type of machine and the position of the mode switch determine when the output of the machine is turned on.

V205-S / V270-S / V405-S: In the stick welding mode, the output of the machine is automatically turned ON. However, in the Lift TIG welding mode, the connection of a remote control determines if the output is ON or OFF. If a remote control is not connected (the Remote LED is OFF) then the output of the machine is automatically turned ON. If a remote control is connected (the Remote LED is

ON) then the output of the machine is turned ON and OFF by the remote connector on the front of the machine.

V205-T / V270-T / V405-T: In stick welding mode, the output of the machine is automatically turned

ON. However, in both of the TIG welding modes, the output of the machine is turned ON and OFF by the TIG torch connected to the trigger connector on the front of the machine.

I. Meter: This meter displays the preset welding current before welding and the actual welding current during welding. Like the output current control, the function of the meter is changed if a remote control is connected. If the Remote LED is

ON, this indicates that a remote control is connected and the meter will display the following information before welding (during welding, the meter always displays the actual welding current):

Stick Welding Mode: The meter displays the preset welding current but this is adjusted from the remote control as explained in the Output Current

Control section.

TIG Welding Modes: The meter displays the maximum output current which is set by the output current control knob. The preset welding current is then adjusted by the remote control, but it is not displayed on the meter.

V205-S / V270-S / V405-S: The machine have a

Voltage / Current switch to change the displayed value on the meter. If this switch is set to voltage, the meter will always display the output voltage of the machine.

J. Output Current Control: This controls the output, or welding, current of the machine.

The function of this control knob is changed if a remote control is connected. If the Remote LED is

ON, this indicates that a remote control is connected and the function of the output current control will be:

Stick Welding Mode: The remote control will adjust the output current of the machine: x V205: from 5 to 200A x V270: from 5 to 270A x V405: from 5 to 400A

The output current control knob on the display panel is not used.

TIG Welding Modes: The maximum output current of the machine is set by the output current control knob. Then the remote control adjusts the output current from the minimum output (5A) to the value set by the output current control knob. For example, if the output current control knob on the machine is set to 100A then the remote control will adjust the output current from a minimum of 5A to a maximum of 100A.

K. Hot Start (V205-S / V270-S / V405-S only): In stick welding mode, this controls the amount of current used during the start of the arc to help ignite the arc quickly and reliably. In TIG welding mode, this is not used.

L. Arc Force (V205-S / V270-S / V405-S only): In stick welding mode, this controls the amount of current used during any intermittent short circuiting of the electrode during welding. In TIG welding mode, this is not used.

M. Trigger Mode Switch (V205-T / V270-T / V405-T only): This switch changes between 2-step and 4step trigger sequences. For an explanation of these trigger sequences refer to the trigger sequences explained below.

N. Pulsing Mode Switch (V205-T / V270-T / V405-T only): In the TIG welding modes, this switch turns the pulsing function ON and controls the pulsing frequency range (20Hz or 300Hz). In Stick welding mode, this is not used.

The Pulsing LED next to the Pulsing Mode Switch shows the pulsing frequency when pulsing is turned

ON. With this indication, the operator can adjust the frequency to the desired value before welding.

(Note: At higher frequencies the LED flashes very fast and seems to be continuously ON however it is pulsing.)

O. Pulsing Frequency Control (V205-T / V270-T /

V405-T only): When the pulsing function is ON, this control knob will adjust the pulsing frequency. The pulsing frequency adjustment range is 0.2-20Hz or

3-300Hz depending on the Pulsing Mode Switch position.

P. Pulsing On-time Control (V205-T / V270-T / V405-T only): When the pulsing function is ON, this control knob will adjust the pulsing on-time. The on-time can be adjusted from 10% to 90% of the pulsing period.

Q. Pulsing Background Current Control (V205-T /

V270-T / V405-T only): When the pulsing function is

ON, this control knob will adjust the pulsing background current. This is the current during the

A-5 low portion of the pulse waveform; it can be adjusted from 10% to 90% of the welding current.

R. Downslope Control (V205-T / V270-T / V405-T only): In the TIG welding modes, this control knob will adjust the downslope time from 0.5 to 20 seconds. (The upslope time is always 0.5 seconds.)

Refer to the trigger sequence section below to understand how downslope is activated. In Stick welding mode, this is not used.

S. Start/Crater Current Control (V205-T / V270-T /

V405-T only): This control knob will adjust the

Start/Crater current from 10% to 90% of the welding current. For an explanation of the start/crater operation, refer to the trigger sequences explained below.

T. Postflow Control (V205-T / V270-T / V405-T only):

In the TIG welding modes, this control knob will adjust the shielding gas postflow time from 0.5 to 30 seconds. (The preflow time is always 0.5 seconds.)

In Stick welding mode, this is not used.

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.

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.

A-6

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.

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.
