Silly Job Title: Solder Soldier. I am the Solder Soldier!
In this video we make a power cable running a DC barrel female socket into hook-clips.
We use the METCAL PS-900 Soldering Station for soldering.
We use the Riden RD6006 Bench Power Supply to provide power for testing.
We use the EEVblog BM2257 Digital Multimeter to test the cable.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
