System:
CD1000DP – 1000ws capacitive discharge resistance welder
WH1125A – Opposed air actuated weld head
1/8″copper upper and lower electrodes (with flat tips)
1awg weld cables
Or
THP-A, pneumatic tweezer hand piece
The WH1125A is configured with 1/8″ copper electrodes in the upper and lower holders that have flat tips. 1awg weld cables are used and the spring force is set to 15lbs for the weld pictured. We chose to use a weld head instead of a hand-piece due to the ability to control the pressure being applied during the weld. Brass welds can be very pressure sensitive since any arcing can cause blow outs. The weld head can deliver consistent repeatable forces that are difficult to achieve by hand. We also offer a pneumatic tweezer hand piece (THP-P) that can provide the consistent high forces necessary.
The CD1000DP is set with Pulse 1 off, Pulse 2 at 1000ws, and Total Energy at 1000ws to perform the welds. These settings are able to lap weld the brass pieces firmly. A slightly smaller tip size could increase weld strength if desired.
