Operating manual
• Connect 5 - PLC mode (TIG 300 DC only):
This mode is used to control the TIG 300 DC from a console or a PLC thanks to its five stored, pre-recorded welding programs.
Based on the foot pedal's mechanism, the 'Switch (D)' can be used to start or stop the welding process according to the selected cycle. The level of
voltage applied to 'Cursor (B)' is controlled by the welding program or by the current welding settings.
This voltage must be between 0 and 10.0 V, rising in increments of 1.6 V, which matches that of a program rerun:
- Background context: 0 - 1.6 V
- Program 1: 1.7 - 3.3 V
- Program 2: 3.4 - 5.0 V
- Program 3: 5.1 - 6.6 V
- Program 4: 6.7 - 8.3 V
- Program 5: 8.4 - 10.0 V
An additional potentiometer allows the current to be varied during and after welding by +/- 15%. The ARC ON data allows the PLC to synchro-
nise itself (100 kΩ Pull Up input on the PLC's side). Earthing the AUTO_DETECT pin allows the product to be started without going through the
remote-control selection screen.
The five stored welding programs represent the first five recorded programs (from P1 to P5).
Signal I / Os are protected.

COOLING UNIT (OPTIONAL EXTRA)
PROTIG 221 DC FV
P 1L/min = 500 W
WCU0.5kW_A Capacity = 1.5 L
U1 = 185 - 265 V
P 1L/min = 1,000 W
WCU1kW_A Capacity: 3 L
U1 = 85 - 265 V
TIG 300 DC
P 1L/min = 1,000 W
WCU1kW_B Capacity: 3 L
U1 = 400 V +/- 15%
The cooling unit will be automatically detected by the product. This cooling unit can be disabled in the 'OPTION' menu.
Holding down the 'JOB' button for longer than three seconds will allow access to the cooling unit's menu.
Make sure that the cooling unit is switched off before disconnecting the input tubes and the torch's liquid outlet.
The coolant is harmful and irritates the eyes, mucous membranes and skin. Hot liquid can cause burns.
ERROR MESSAGES, DEFECTS, CAUSES AND SOLUTIONS
This equipment includes a failure-control system.
A series of messages on the display screen will allow errors and anomalies to be diagnosed.

Translation of the original
instructions
The cooling unit is activated when the machine's supply-voltage range is between 185 - 265 V.
The cooling unit is always active when the supply-voltage range is between 85 - 185 V.
The cooling unit is controlled across the entire voltage-supply range of 85 - 265 V.
The cooling unit is controlled across the entire voltage-supply range.
CAUSES
Welding power source
Lack of communication
Defective HMI buttons
The torch's trigger (or triggers) is faulty
The foot pedal's switch is defective or still active
An operation fault is detected in PLC mode
A network surge has occurred
The three-phase network is missing one phase

SOLUTIONS
Check the internal wiring between the HMI
and the power board
Replace the HMI device
Replace the torch
Replace the pedal or check that the switch
has not been pressed down
Check the PLC control's wiring
An overvoltage has caused this
message, for example, engine-load release
or lightning, etc
This machine requires a three-phase power
supply (3P + N + Earth)
