Product Name
Leister 101.721 LABOR S Slim Design multi-use air hand tool (ROBUST Blower or air compressor not included)
Brief Description
The Leister LABOR S (101.721) is a compact, lightweight, and versatile hot air hand tool designed for delicate and difficult hot-air applications. It requires an external air supply from a Leister ROBUST or MINOR blower, or a standard air compressor. This tool is particularly suited for precision work in confined spaces and offers stepless temperature adjustment.
Popular Applications & Uses
- Plastic welding of thermoplastics, single-ply flexible plastics, and modified bitumen in various forms (sheets, tubes, profiles, films, foams).- Shrinking heat shrink sleeves, films, tapes, and solder sleeves.- Soldering and desoldering of SMD and thru-hole electronic components.- Activating and loosening solvent-free adhesives and melt adhesives.- Drying water-damp surfaces.- Consolidating flaking paint and splitting paper in restoration work.- Curing adhesives.- Restoring various items and museum conservation work.
Industries that Commonly Use It
- Plastic Fabrication: For precise welding of various plastic materials.- Artist, Artisan: Utilized in museum conservation, artifact restoration, and paper/book repair.- Construction/Building Services: For specialized plastic welding tasks, including architectural restoration and delicate roofing membrane work.- General Manufacturing: Applicable for general heating, drying, shrinking, and adhesive activation processes.- LED/Electronics: Essential for soldering and desoldering sensitive electronic components.- Tarp, Fabric, Awning Manufacturing: Used for welding flexible plastics, coated fabrics, and films.- Thermoforming: For forming and shaping thermoplastics.
Special and Unique Features
- Slim and lightweight design (approx. 150-180g without cord) for fatigue-free operation, even in small hands.- Ideal for welding in difficult-to-access locations and confined spaces.- Stepless temperature adjustment via a conveniently positioned rotary knob (20 - 600 °C).- Requires an external air supply (Leister ROBUST/MINOR blower or compressed air), making the hand tool itself very light.- Equipped with a protective tube that also serves as a handle, ensuring additional safety against burns.- Wide range of compatible nozzles and accessories for diverse applications.
Key Properties
- Voltage: 120 V (also available in 230 V).- Power Consumption: 600 W (120V version).- Temperature Range: 20 - 600 °C (68 - 1112 °F).- Frequency: 50/60 Hz.- Weight: Approximately 0.15 - 0.18 kg (0.33 - 0.39 lbs) without power cord and air hose.- Nozzle Connection Diameter: 21.3 mm (0.85 in).- Air Hose Length: Up to 3 meters.- Approvals: CE, QPS (for some versions).- Electrical Protection: Class II.
Surface Compatibility
- Thermoplastic materials (PVC, polyester, polyethylene, etc.).- Single-ply flexible plastics.- Modified bitumen.- Heat shrink materials (sleeves, films, tapes).- Electronic components (SMD, thru-hole).- Surfaces requiring adhesive activation or drying.- Flaking paint and paper for conservation.
Known backups / known substitutes
- Leister DIODE PID/S hot air hand tools.- Leister WELDING PEN R/S hot air hand tools.- Leister HOT JET S hot air hand tool (self-contained, heavier).- Leister PENWELD A/S hot air welding devices.- Leister TRIAC ST hot air hand tool (more robust, often for construction sites).- Other brands' hot air guns or heat guns with similar temperature and airflow capabilities, often requiring specific nozzles for precision work.
Comparison Note
The Leister LABOR S stands out from other Leister hot air tools like the TRIAC ST or HOT JET S due to its exceptionally lightweight and slim design, which is achieved by utilizing an external air blower or compressor. This makes it ideal for highly precise, delicate, and extended work in laboratories, conservation, or tight spaces where user fatigue is a concern, unlike the more self-contained and heavier tools designed for general construction or heavy-duty applications.
