1. Product Range and Technical Specifications

The TBi Expert Series MIG/MAG welding torches include two main categories: Classic Series and Top 2000 Series. Classic Series models (e.g., TBi 150, 240, 250, 260, 360, 351, 241, 411 Expert) offer duty cycles from 60% to 100% at 10 minutes, with current ratings between 150 A and 450 A depending on model and shielding gas (mixed gas or CO2). Top 2000 Series torches (e.g., TBi 7G, 7W, 511-CC, 7W-CC Expert) provide higher current capacities up to 550 A and feature advanced 2-circuit water cooling systems.

Wire diameter compatibility ranges from 0.6 mm to 1.6 mm, varying by model. Cooling methods include gas cooling (standard in Classic Series) and water cooling (standard in Top 2000 Series). Duty cycles and current ratings are specified per model, for example, TBi 150 Expert supports 150 A (mixed gas) and 180 A (CO2) at 60% duty cycle, while TBi 511-CC Expert supports 500 A (mixed gas) and 550 A (CO2) at 100% duty cycle.

2. Standards and Compliance

• All torches comply with IEC 60974-7 standards ensuring safety and performance.
• Standard connection is via Euro-Central connectors; alternative connectors are available upon request.
• Users should note that torch current ratings decrease when used with pulsed-arc power sources.

3. Spare Parts and Consumables

The document provides comprehensive spare parts lists for each torch model, including torch necks, nozzle holders, springs, insulators, handles (standard and long trigger), screws, triggers, and cable supports. Contact tips are available in multiple materials (ECu, CuCrZr, Alu ECu) and sizes (M6, M8), with part numbers tailored to wire diameter and torch length.

Gas nozzles and diffusors come in various shapes (conical, cylindrical, spot welding) and sizes (NW 9.5 mm to NW 20 mm), including heavy-duty and long insulation variants. Additional accessories include cable lugs, insulated connectors, coaxial cables (16 qmm to 50 qmm), adaptor nuts, O-rings, and screws.

4. Ordering Information

• Torches are supplied pre-equipped for steel wire diameters such as 0.8 mm, 1.0 mm, and 1.2 mm.
• Available cable lengths include 3 m, 4 m, and 5 m, with options for standard or long trigger handles.
• Part numbers include placeholders for specific configurations (e.g., torch length, wire diameter) to facilitate precise ordering.

5. Key Parameters and Recommendations

• Gas Flow Rates: Recommended flow rates range from 10 to 16 liters per minute depending on torch model and wire diameter.
• Wire Diameter: Must be matched to torch specifications for optimal welding performance.
• Cooling Method: Choice between gas and water cooling impacts duty cycle and current capacity.
• Connectors: Euro-Central connectors are standard; alternative connectors can be requested.
• Pulsed-Arc Power Sources: Expect reduced torch ratings when using pulsed-arc technology.

6. Components and Accessories

Components include cable lugs, insulated connectors, hose clamps, quick connectors, cable assemblies, and covers. Gas diffusors are available in thermoset (black, robust), ceramic (white, heat resistant), and rubber (red, long life) materials. Gas nozzles vary in shape and size to suit different welding applications.

Contact tips and tip holders come in various materials and sizes, including longer and cooled variants. Handles and triggers are offered in water-cooled versions with standard or long trigger options. Fastening components such as adaptor nuts, sleeve nuts, O-rings, and screws are also detailed.

7. Consumables and Wire Guides

• Wire liners are available for steel, stainless steel, aluminum, and mixed wires, made from materials like insulated/non-insulated PA, PTFE, Carbon-PTFE, and CeraGlide, color-coded by wire diameter.
• Support tubes stabilize plastic liners inside Euro connectors to prevent bending.
• Wire cleaning felts help remove dirt and grease, improving wire feeding and arc ignition.

8. Accessories for Safety and Efficiency

• TBi ArcVisor automatic welding helmet with adjustable dark shade (DIN 9-13) enhances operator safety.
• MIG/MAG welding gloves made from cow split leather with moisture-absorbing lining and reinforced palms improve ergonomics and protection.
• Anti-spatter products include silicone and water-free sprays (temperature resistant to 180 °C) and Tip-Dip paste to prevent spatter adhesion and extend nozzle life.
• Magnetic and universal torch supports provide safe placement for hot torches.
• Specialized tools such as MIG/MAG Multi-Tool, gas nozzle cleaner, and TBi MIG-Tool facilitate maintenance and consumable replacement.
• Gas flow meters measure flow rates from 3 to 25 l/min for Ar and CO2 gases.
• Ground cables of various cross-sections (16 mm² to 70 mm²) with brass clamps support currents from 150 A to 500 A at 60% duty cycle.
• Cooling units like the TBi beCool 2.2 recirculation cooler offer 2,200 W cooling power, max 4 bar water pressure, thermal protection, and optional sensors. Recommended cooling fluid includes corrosion inhibitors and antifreeze protection to -26 °C.
