3. Setup Guide

3.1 Power Connection

The S7 TIG-200 welder supports dual voltage input (110V/220V). Ensure your power source matches the machine's requirements and use the appropriate adapter if necessary.

• Connect the power cable to a suitable electrical outlet.
• Verify the voltage setting on the machine, if adjustable, matches your power supply.

3.2 Connecting Accessories

Proper connection of welding accessories is crucial for safe and effective operation.

• TIG Torch: Connect the TIG torch cable to the designated TIG output terminal on the front panel. Ensure a secure connection.
• Ground Clamp: Attach the ground clamp cable to the workpiece or welding table, ensuring good electrical contact. Connect the other end to the ground terminal on the welder.
• Electrode Holder (for ARC welding): If performing ARC welding, connect the electrode holder cable to the appropriate terminal.
• Gas Hose (for TIG welding): Connect your shielding gas supply (e.g., Argon) to the gas inlet on the rear of the machine using a suitable hose and regulator.

4. Operating Modes

The S7 TIG-200 offers three primary welding modes: DC TIG, Pulse TIG, and ARC (Stick) welding.

4.1 TIG Welding (DC TIG / Pulse TIG)

• Material Compatibility: Ideal for stainless steel, mild steel, copper, alloy steel, iron, and carbon steel.
• Welding Thickness: Supports thicknesses from 0.3mm to 4.8mm.
• Features: Utilizes hot start TIG and non-contact arc initiation for clean and efficient starts.
• Procedure: Ensure proper shielding gas flow. Set desired amperage and pulse settings (if using Pulse TIG). Maintain a consistent arc length and travel speed for optimal results.

4.2 ARC Welding (Stick Welding)

• Material Compatibility: Suitable for various ferrous metals.
• Welding Thickness: Supports thicknesses from 15mm to 42mm.
• Procedure: Select the appropriate electrode for your material and application. Set the amperage according to the electrode manufacturer's recommendations. Maintain a steady hand and consistent arc.

5. Maintenance

Regular maintenance ensures the longevity and reliable performance of your S7 TIG-200 welder.

• Cleaning: Periodically clean the exterior of the machine with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. For internal cleaning, consult a qualified technician.
• Cable Inspection: Regularly inspect all welding cables, torch, and ground clamp for any signs of damage, fraying, or loose connections. Replace damaged components immediately.
• Consumables: Check and replace TIG torch consumables (collets, collet bodies, ceramic cups, tungsten electrodes) as they wear out to maintain arc quality.
• Storage: Store the welder in a clean, dry environment, away from excessive dust, moisture, and corrosive materials.
