Brazing small copper wire

Objective
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
UPT SH2 Power Supply
HS4W Heat Station

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 UPT SH2 System with 1m (3.3 ft) flexible leads and an open C-coil. For even faster braze times, a UPT SM5 System is recommended.
