Operating Instructions
Detailed steps for using the Leister Triac ST plastic welder.
1. Powering On and Temperature Adjustment
- Plug the power cord into a suitable 120 Volt AC outlet.
- Turn the main power switch to the "ON" position.
- Adjust the temperature using the rotary knob on the tool. The temperature is continuously adjustable from 40°C to 700°C (100°F to 1290°F). Start with a lower setting and gradually increase as needed for your specific material.
- Allow a few minutes for the tool to reach the desired operating temperature.
2. Welding and Processing
- Position the nozzle approximately 5-10 mm from the material surface.
- Move the tool steadily along the seam or area to be processed, ensuring even heat distribution.
- For welding, apply appropriate pressure with the seam roller immediately after heating to ensure a strong bond.
- Observe the material's reaction to the heat to determine the correct temperature and speed.
3. Powering Off
- Turn the temperature knob to the lowest setting.
- Turn the main power switch to the "OFF" position.
- Allow the tool to cool down completely before unplugging or storing. The tool has a built-in cool-down function that continues to blow air until the heating element is safe to handle.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your tool.
1. Cleaning Air Filters
- The Triac ST features easily removable two-sided air filters.
- Regularly check the air filters for dust and debris.
- To clean, remove the filters and gently brush off any accumulated dirt. You may also use compressed air.
- Ensure filters are completely dry before reinserting them. Clean filters ensure optimal air supply and maximum performance.
2. General Cleaning and Storage
- After each use, allow the tool to cool down completely.
- Wipe the exterior of the tool with a clean, dry cloth. Do not use solvents.
- Store the tool and its accessories in the provided carrying case in a dry, safe place, away from direct sunlight and extreme temperatures.
