User Manual for GYS PROGYS 200A PFC Welding Machine

Quick guide from the manual

The GYS PROGYS 200A PFC is a portable, fan-cooled inverter welding machine designed for MMA (coated electrode) and TIG Lift welding. It is compatible with 230V single-phase power supplies and can be used with electric generators. Always ensure the machine is unplugged before performing any installation or maintenance.

Safety Rules

• Electrical Safety: The machine must be connected to an earthed electrical supply. Never touch live parts inside or outside the machine. Disconnect from the mains and wait 2 minutes before opening the device to allow capacitors to discharge.
• Welding Fumes and Gas: Ensure adequate ventilation. Welding in small areas requires supervision. Degrease workpieces before welding.
• Fire and Explosion Risks: Keep flammable materials at least 11 meters away. Do not weld near grease or paint.
• Electromagnetic Fields: Minimize exposure by keeping welding cables together, keeping your head and torso as far as possible from the welding circuit, and never wrapping cables around your body.

Installation and Setup

Only qualified personnel should perform the installation. Ensure the machine is placed on a floor with a maximum incline of 10° and has sufficient ventilation. The machine has an IP21 protection rating, meaning it is protected against solid objects >12.5mm and vertically falling water drops.

MMA Welding (Electrode)

1. Connect the electrode holder and earth clamp to the connectors.
2. Select the MMA position (2) using the selector (5). Press for 3 seconds to switch modes if necessary.
3. Adjust the desired current using the keys (4).
4. The machine features Hot Start (easier arc ignition), Arc Force (prevents sticking), and Anti-Sticking (allows easy electrode removal).

TIG Welding (TIG Lift)

1. Connect the earth clamp to the positive pole (+) and the valve torch to the negative pole (-).
2. Connect the gas hose to the gas cylinder regulator.
3. Select the TIG position (3) using the selector (5).
4. Adjust the current and set the gas flow on the regulator.
5. To start, touch the electrode to the workpiece.
6. At the end of welding, lift the arc twice (up-down-up-down) within 4 seconds to trigger the automatic arc slope (if enabled).

Maintenance

• Annual maintenance is recommended.
• Regularly remove the casing (2-3 times a year) to remove dust with compressed air.
• Check the condition of the power supply cable regularly.
• Keep ventilation holes clear for proper air circulation.

Troubleshooting

If the thermal protection indicator (6) lights up, wait for the cooling period (approx. 2 minutes) until it turns off. If the display is on but no current is delivered, check the connections of the earth clamp and electrode holder. If the machine is not welding correctly, check the polarity.
