4. Setup
Follow these steps to set up your CaddyTig 2200i TA34 AC/DC welding machine:
- Power Connection: Connect the machine to a single-phase power supply. Ensure the power source meets the machine's requirements. The integrated PFC circuit allows for use with extra-long mains cables (over 100m) and portable generators.
- Gas Connection: Connect the appropriate shielding gas cylinder (e.g., Argon for TIG welding) to the gas inlet on the machine. Ensure all connections are secure and leak-free.
- Torch Connection: Connect the TIG torch to the designated connector on the machine. The CaddyTig 2200i AC/DC features robust, shock-resistant cable connectors with OKC 50.
- Work Clamp Connection: Attach the work clamp cable to the machine and securely fasten the clamp to the workpiece or welding table, ensuring good electrical contact.
- Electrode Installation: Install the correct tungsten electrode into the TIG torch collet, ensuring proper stick-out for your application.
- Ventilation: Ensure adequate ventilation in the welding area to disperse fumes and gases.
5. Operating
The CaddyTig 2200i TA34 AC/DC offers advanced controls for precise welding.
- Power On: Turn on the main power switch. The control panel will illuminate.
- Parameter Setting (TA34): The TA34 version is designed to support and enhance the welder's skills. It allows for excellent welding results across a wide range of materials and thicknesses.
- AC/DC Mode Selection: Select either AC (for aluminum and magnesium) or DC (for steel, stainless steel, copper, etc.) welding mode based on the material.
- Current Adjustment: Adjust the welding current (amperage) according to the material thickness and type.
- AC Frequency and Balance (AC Mode): Fine-tune AC frequency and balance to optimize arc stability and cleaning action on aluminum.
- Pulsed TIG (DC Mode): Activate and adjust pulse parameters (peak current, base current, pulse frequency) for better heat input control, especially on thin materials. The Micro Pulse function further minimizes the heat-affected zone.
- Upslope/Downslope (TA34): The TA34 version comes with adjustable upslope and downslope, allowing for controlled start and end of the weld bead, preventing crater defects.
- 2-Program Function (TA34): Utilize the 2-program function to pre-set and quickly switch between different welding parameters for varying tasks or material thicknesses during a single welding session.
- Initiating Arc: Use the torch trigger to initiate the arc. Maintain proper arc length and torch angle for optimal results.
- Post-Flow: Allow the gas post-flow to protect the cooling weld and electrode from atmospheric contamination.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding machine.
- Cleaning: Periodically clean the machine's exterior with a dry cloth. Use compressed air to blow out dust and debris from inside the machine, especially from cooling vents. Ensure the machine is disconnected from power before cleaning.
- Cable and Connector Inspection: Regularly inspect all cables (power, torch, work clamp) for damage, cuts, or frayed insulation. Check connectors for tightness and corrosion. Replace damaged components immediately.
- Torch Maintenance: Inspect the TIG torch consumables (collet, collet body, ceramic cup, tungsten electrode) regularly. Replace worn or damaged parts to ensure consistent arc quality.
- Gas System Check: Verify that gas hoses are not kinked or leaking. Ensure the gas regulator is functioning correctly.
- Storage: Store the machine in a clean, dry environment when not in use, protected from dust and moisture.
7. Troubleshooting
This section provides solutions to common issues you might encounter. For problems not listed here, contact qualified service personnel.
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not power on. | No power from outlet; tripped circuit breaker; faulty power cable. | Check power supply; reset breaker; inspect power cable for damage. |
| No arc or weak arc. | Poor work clamp connection; incorrect gas flow; contaminated tungsten; wrong current setting. | Ensure good work clamp contact; check gas supply and flow rate; clean or replace tungsten; adjust current. |
| Porous weld. | Insufficient shielding gas; gas leak; contaminated base metal; incorrect torch angle. | Check gas cylinder level and flow; inspect gas lines for leaks; clean workpiece thoroughly; adjust torch angle. |
| Tungsten electrode contamination. | Touching workpiece with tungsten; insufficient gas post-flow; wrong current for tungsten size. | Maintain proper arc length; increase gas post-flow time; use appropriate tungsten size for current. |
