4. Configurare
Proper setup is crucial for safe and effective welding. Follow these steps carefully.
4.1 Despachetarea și inspecția:
- Remove the welder and all accessories from the packaging.
- Inspect for any shipping damage. Contact your supplier immediately if damage is found.
- Asigurați-vă că sunt prezente toate componentele enumerate în lista de ambalare.
4.2 Connecting Accessories:

Image 4.1: Electrode holder and ground clamp conexiuni.
- Pământ Clamp Conexiune: Conectați masa clamp cable to the negative (-) output terminal on the welder. Securely attach the ground clamp la piesa de lucru sau la masa de sudură, asigurând un contact electric bun.
- Electrode Holder Connection (for MMA/Stick): Connect the electrode holder cable to the positive (+) output terminal on the welder. Insert the welding electrode into the holder.
- TIG Torch Connection (for Lift TIG - torch sold separately): If performing Lift TIG welding, connect the TIG torch cable to the negative (-) output terminal. Connect the gas hose from the TIG torch to your argon gas regulator.
4.3 Conexiune la alimentare:
- Asigurați-vă că întrerupătorul de alimentare al aparatului de sudură este în poziția OPRIT.
- Connect the power input cable to a suitable 230V power outlet. Verify that the power source meets the welder's requirements.
5. Instrucțiuni de utilizare
The YESWELDER 205A offers two primary welding modes: Stick (MMA) and Lift TIG.
5.1 Starting the Welder:
- After connecting all cables and ensuring safety, turn the power switch to the ON position.
- The LED display will illuminate, showing the default welding mode and current.
5.2 Stick (MMA) Welding:

Image 5.1: Visual representation of Stick welding (left) and Lift TIG welding (right).
- Selectați modul: Press the 'Welding Mode Button' until 'Stick' (MMA) is indicated on the display.
- Set Current: Use the 'Value Knob' to adjust the welding current (amperes) according to the electrode type and material thickness. The machine supports up to 205A.
- Adjust Parameters (Optional): Press the 'Parameter Button' to cycle through Hot Start and Arc Force settings. Adjust these using the 'Value Knob' as needed for optimal arc ignition and stability.
- Începeți sudarea: Strike the arc by lightly touching the electrode to the workpiece and quickly lifting it slightly. Maintain a consistent arc length and travel speed.
5.3 Lift TIG Welding:
For Lift TIG welding, a TIG torch with a gas valve is required (not included).
- Selectați modul: Press the 'Welding Mode Button' until 'Lift TIG' is indicated on the display.
- Set Current: Use the 'Value Knob' to adjust the welding current (amperes) based on the material and tungsten electrode size.
- Debit de gaz: Open the gas valve on the TIG torch to establish argon gas flow.
- Inițiază Arcul: Gently touch the tungsten electrode to the workpiece and then lift it slightly (1-2mm) to initiate the arc. The arc will start at a low current and ramp up to the set current.
- Perform Weld: Maintain a short arc length and feed filler rod manually if required.
