Coated Electrode Welding (Mma); Mma Pulse - GYS PROTIG 201 AC/DC Manual De Instrucciones

Translation of the original instructions
" AC " button
•
Use of the "AC" button in "AC - Easy" mode : Pressing this button gives access to the tungsten electrode diameter setting. The setting of this parame-
ter is done as follows:
- Press the "AC" key,
- Within 3 seconds, activate the incremental encoder. An clockwise rotation of this encoder leads to an increase in the electrode diameter and a
anti-clockwise rotation leads to a decrease in the value of the electrode diameter. The selected electrode value is visible on the HMI LEDs below the
AC Easy mode.
- Once the setting has been made, after 2 seconds without activating the incremental encoder, it is again linked to the current setting.
Using the " AC " button in " AC " mode : Pressing this button allows you to select and adjust the " Balance " and " Frequency " parameters (the asso-
ciated LED lights up according to the selected parameter). The incremental encoder acts on these 2 parameters values and must be actuated within
5 seconds. Beyond that, the power source will display the welding current again.
Frequency adjustment in TIG AC (Frequency)
•
The welding current frequency setting for TIG AC ranges from 20 Hz to 200 Hz.
Balance adjustment in TIG AC (Balance)
•
The welding balance setting for TIG AC ranges from 20 % to 60 %. The incremental step is 1%.
Note: The "AC" key is not active in "DC" mode.
HIDDEN MODE
A hidden mode is available for each of the welding processes: DC TIG, AC TIG and MMA. This mode is designed to allow the setting of additional
parameters for each of these processes.
The changes of the values of accessible parameters in the hidden mode are kept when saving a job.
Accessibility, navigation and settings in hidden mode:
DC TIG and AC TIG:
Access the hidden mode by pressing the
The machine now displays "CoU". By turning the main encoder, it is possible to access to " ISA", "TSA", "ISO", "TSO" and "ESC".
To access the setting of these parameters, press the A/V button again.
• CoU : Activate or deactivate the Cooling Unit by selecting "ON" or "OFF". The selection between "ON" and "OFF" is made by activating the main
encoder and then pressing the A/V button. This only applies to the "201 L AC/DC" version.
• ISA : Set the starting current. It is set as a percentage of the welding current setpoint. It can be adjusted between 10% and 200%. Validate the
entered setting by pressing the A/V button.
• TSA : Set the duration of the starting current. Time is adjustable from 0s to 10s, validate the entered setting by pressing the A/V button.
• ISO : Set the welding end current, it is set as a percentage of the welding current setpoint. It can be adjusted between 10% and 200%. Validate
the entered setting by pressing the A/V button.
• TSO : Set the duration of the welding current. Time is adjustable from 0s to 10s, validate the entered setting by pressing the A/V button.
• ESC : Press the A/V button to exit the hidden mode. You can also exit the hidden mode by waiting three seconds after setting a hidden mode
parameter. The display then returns to the welding current setpoint setting.
MMA :
Access the hidden mode by pressing the
The machine now displays "HST". By turning the main encoder it is possible to access "AST" and "ESC".
• HST : Set the duration of the HotStart. This time is adjustable from 0.1s to 2s. Validate the entered setting by pressing the A/V button.
• AST : Activate or deactivate the Antisticking by selecting "ON" or "OFF". Validate the entered setting by pressing the A/V button.
• ESC : Press the A/V button to exit the hidden mode. You can also exit the hidden mode by waiting three seconds after setting a hidden mode
parameter. The display then returns to the welding current setpoint setting.

COATED ELECTRODE WELDING (MMA)

CONNECTIONS AND RECOMMENDATIONS
• Connect the electrode holder and the earth clamp into the connectors provided for this purpose, taking care to respect the welding polarities and
intensities indicated on the electrodes boxes.
• Remove the electrode from the electrode holder when the machine is not in use.
• The machines have 3 features exclusive to Inverters:
- The Hot Start creates an overcurrent at the beginning of the weld to prevent sticking.
- The Arc Force creates an overcurrent which prevents the electrode from sticking to the weld pool.
- The Anti-Sticking technology makes it easier to unstick the electrode from the metal.

MMA PULSE

This MMA Pulse welding mode is suitable for applications in the vertical up position (PF). The pulse mode keeps the weld pool cold and eases the
transfer of matter. Without the pulse mode, vertical-up welding requires a difficult "Christmas tree" shape triangular movement. With the MMA Pulsed
mode, this movement is no longer required and a simple straight up movement is enough (depending on the thickness of the workpiece). If you
wish to widen your weld pool, a simple lateral movement is enough (similar to normal welding). This process allows greater control during vertical-up
welding. The pulse frequency is adjustable from 0.4 Hz to 20 Hz.
