4. Instruccions de configuració
4.1. Precaucions de seguretat
Always ensure proper ventilation, wear appropriate personal protective equipment (PPE) including welding helmet, gloves, and protective clothing. Disconnect power before making any connections or adjustments.
4.2. Connexió d'alimentació
- Identify your power source: The TIG220ACDCP supports both 110V and 220V.
- For 220V operation, connect the welder directly to a compatible 220V outlet.
- For 110V operation, use the provided 220V to 110V adapter to connect the welder to a 110V outlet.
- Ensure the power outlet is properly grounded and capable of handling the welder's current requirements.
4.3. Gas Connection (TIG Welding)
- Connect the Argon Gas Hose to the gas inlet on the rear of the welder.
- Connect the other end of the gas hose to your Argon gas cylinder regulator.
- Assegureu-vos que totes les connexions estiguin ben ajustades per evitar fuites de gas.
- Set the gas flow rate on your regulator according to your welding application (typically 15-25 CFH for TIG).
4.4. Torxa i escalfador de terraamp Connexió
- Connect the 13ft TIG Torch to the appropriate TIG torch connector on the front panel of the welder.
- Connect the 6ft Ground Clamp cable al terminal de terra del panell frontal.
- For MMA (Stick) welding, connect the 6ft MMA Electrode Holder to the positive terminal and the Ground Clamp al terminal negatiu.
5. Instruccions de funcionament
5.1. Tauler de control acabatview
The LOTOS TIG220ACDCP features an intuitive digital control interface with an LCD display and a single encoder knob for parameter adjustments.
Imatge: Primer pla view of the digital control panel with LCD display, buttons, and encoder knob.
5.2. Selecting Welding Mode
Use the "PROCESS" button to cycle through the available welding modes: AC TIG (Pulse/Spot/HF), DC TIG (Pulse/Spot/HF), and MMA Stick.
5.3. Ajust de paràmetres
Once a mode is selected, use the encoder knob to navigate through and adjust various welding parameters displayed on the LCD screen. Press the knob to confirm selections or switch between parameters.
- Ampera: Set the desired welding current.
- Preflux/Postflux: Adjust the gas flow duration before and after welding.
- Slope Up/Down: Controla la ramp-amunt i ramp-down time of the welding current.
- Freqüència de CA: (AC TIG only) Adjust for arc cone width and cleaning action.
- Balanç de CA: (AC TIG only) Controls the ratio of electrode negative (EN) to electrode positive (EP) for cleaning action.
- Configuració del pols: (Pulse modes only) Adjust pulse frequency, peak current, base current, and pulse width.
5.4. Saving and Recalling Profiles
The welder allows you to save up to 10 custom welding profiles for quick access:
- Desa: Set your desired parameters, then press and hold the "SAVE" button for 3 seconds. Select a memory slot to store the profile.
- Recorda: Press the "RECALL" button and use the encoder knob to select the desired saved profile.
5.5. Tècniques de soldadura
Refer to standard welding practices and safety guidelines for specific techniques related to TIG and Stick welding. Always practice on scrap material before welding on your final workpiece.
