High Frequency Induction Brazing Copper Wire

Objective High frequency induction Braze a 5.3 sq mm (10 gauge) and a 0.5 sq mm (20 gauge) copper wire using induction with an open C-coil. Equipment DW-UHF-6KW-III handheld induction brazing heater Open C-coil Flexible Leads Materials • 10 gauge (5.3 sq mm) copper wire • 20 gauge wire (0.5 sq mm) copper wire • Brazing alloy • Brazing flux

Test 1 Power: 2 kW Temperature: 815° C (1500° F) Time: 42 sec

Test 2 Power: 2 kW Temperature: 815° C (1500° F) Time: 38 sec

Test 2 Power: 4.86 kW Temperature: 815° C (1500° F) Time: 10 sec

Results and Conclusions: Brazing the two types of copper wire is possible with the DW-UHF-6KW-III handheld induction brazing System with 1m (3.3 ft) flexible leads and an open C-coil. For even faster braze times, a DW-UHF-10kw induction System is recommended.
