Model: TGF3000-V1  |  Max Temp: 1100°C (2000°F)  |  Power: 1800W  |  Weight: 7.5 kg  |  Material: Ceramic  |  Melting Time: 25–35 min  |  Voltage: 110V (US)

Key Features

• Everyday Home Melting: Designed for hobbyists, the 1800W furnace melts 3 kg of copper in approximately 28 minutes — over 100% more efficient than older models. Its smart heat-transfer design makes casting accessible for all skill levels.
• Fast Melting: Melt 3 kg of copper in 25–35 min or 1 kg of silver in 18 min. Delivers 2.1× the efficiency of prior units with 22% less energy use.
• Precise PID Temperature Control: Upgraded PID controller delivers ±3°C accuracy (vs. ±15°C in standard furnaces), fast response, and minimal overshoot. Real-time LED display ensures reliable, professional-grade results.
• Ultra-Stable Base: Hexagonal weighted base with anti-slip silicone feet stays secure on slopes up to 15° or uneven floors — ideal for balconies, garages, or classrooms.
• Complete Starter Kit: Includes furnace, 3 kg and 1 kg graphite crucibles, 10-cavity ingot mold, tongs, gloves, and bilingual manual. Ready to use in 5 minutes.

Compatible Metals

The TRF3000 melts a wide range of metals including aluminum, copper, silver, gold, lead, zinc, and brass. Ideal for jewelry making, scrap metal recycling, small-batch refining, hobby casting, and DIY metalworking.

Heating Performance & Power Requirements

The built-in PID digital temperature controller provides precise regulation and stable heating throughout the melting process, reducing temperature fluctuation for consistent results. Due to its 1800W heating power, a stable electrical supply is required. This unit uses a standard US 3-prong plug (Type A/B, 110V) — compatible with standard North American outlets. For best performance, use a 20A dedicated circuit and a 12AWG heavy-duty extension cord. Using an insufficient power supply may cause breaker trips or unstable heating.

Durability & Maintenance Tips

The TRF3000 is designed for light-to-moderate hobby use and small-scale metalworking. To maximize lifespan: preheat the crucible gradually before use, avoid unnecessary overheating, apply borax coating when appropriate, and regularly inspect heating elements, temperature probes, and crucibles. Crucible lifespan varies by metal type and operating temperature — keep spare crucibles on hand for frequent projects.

Safety Information

The electric resistance heating design provides stable, flameless operation. However, molten metals reach extremely high temperatures and require strict safety precautions. Always wear heat-resistant gloves and eye or face protection. Operate on a stable, heat-resistant surface in a well-ventilated area. Keep flammable materials away from the workspace. Outdoor or garage use is recommended whenever possible.

Recommended Usage Tips

For best results: preheat the crucible before operation, apply borax coating when appropriate, use a dedicated 20A circuit with a 12AWG heavy-duty extension cord, select the correct crucible size for your material quantity, avoid unnecessary overheating, and always wear proper PPE.
