4. Setup

Proper setup is crucial for safe and effective welding. Follow these steps carefully.

4.1 Unpacking and Inspection:

• Remove the welder and all accessories from the packaging.
• Inspect for any shipping damage. Contact your supplier immediately if damage is found.
• Ensure all components listed in the packing list are present.

4.2 Connecting Accessories:

1. Ground Clamp Connection: Connect the ground clamp cable to the negative (-) output terminal on the welder. Securely attach the ground clamp to the workpiece or welding table, ensuring good electrical contact.
2. 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.
3. 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 Power Connection:

• Ensure the welder's power switch is in the OFF position.
• Connect the power input cable to a suitable 230V power outlet. Verify that the power source meets the welder's requirements.

5. Operating Instructions

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:

1. Select Mode: Press the 'Welding Mode Button' until 'Stick' (MMA) is indicated on the display.
2. 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.
3. 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.
4. Begin Welding: 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).

1. Select Mode: Press the 'Welding Mode Button' until 'Lift TIG' is indicated on the display.
2. Set Current: Use the 'Value Knob' to adjust the welding current (amperes) based on the material and tungsten electrode size.
3. Gas Flow: Open the gas valve on the TIG torch to establish argon gas flow.
4. Initiate Arc: 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.
5. Perform Weld: Maintain a short arc length and feed filler rod manually if required.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welder.

6.1 Daily Maintenance:

• Clean the exterior of the machine with a dry, soft cloth.
• Inspect all cables and connections for damage or loose fittings.
• Check the electrode holder and ground clamp for wear.

6.2 Periodic Maintenance (Monthly/Quarterly):

• Internal Cleaning: Disconnect power. Open the machine casing and use compressed air to blow out dust and debris from the cooling fins and internal components. Ensure no moisture enters.
• Fan Check: Verify that the cooling fan operates freely and is not obstructed.
• Terminal Inspection: Check all power terminals for corrosion or looseness. Tighten if necessary.

Caution: Only qualified personnel should perform internal maintenance. Always disconnect power before opening the machine.
