Tinned two 4 AWG (and one 6 AWG) welding cable pics

[Jacotenente]

Used a solder pot and a stick of 60/40 solder (non rosin core). Worked great. Had to file/grind a little to make a solid fit. See pics below.

Do I see three 4awg and one 8awg?

Chris....OMG.... any count number on # of strands?

Walt.... cold it be 19 stand ?6?AWG ??

The two on the left are TEMCo 4 AWG, the black NEG PV feeder cable is 10 AWG (not sure of the strand count), and the POS red on the right is TEMCo 6 AWG. It is same for all three Classics (didn't post redundant pics)...

I really don't know the strand count...it is TEMCo #4 and #6 welding cable. LOTS of fine strands. I did a video on my Channel...here a link to it if you want to see how I did it with the Solder Pot: https://www.youtube.com/watch?v=fH3SMjLpsxs

looks like  .... A lot...

6 AWG

Conductor Stranding: 259/0.01 in.
Nominal Outside Diameter (in.): 0.32
Max Amps: 115

4 AWG

Conductor Stranding: 364/0.01 in.
Nominal Outside Diameter (in.): 0.348
Max Amps: 150

Beware that these type of connections where a soldered multi strand is put under pressure can suffer from creep. The connection can become loose and burn. I have seen this happen a couple of times.
Cheers,

yes so have i.

Very nice job Chris! I would agree you need to keep an eye on those connections being torqued down and believe you do. Ive never seen it done that way before so ill keep it in mind

Curious...what exactly is "creep".

[Westbranch]

I use the word 'flow' as the copper 'moves ' or 'flows' when compressed and the connection can become loose over time, hence why it is recommended to re-torque new connections  after 24 hours....

Will do...

Creep is a function of the solder not the copper. Best to crimp with ferrules.
I grabbed some info from Google.
Cheers,
"Under constant load or stress, solder undergoes progressive inelastic deformations over time. This time dependent deformation is called creep and the associated strains that develop over time are creep strains. When the test specimen is subjected to a constant load, the initial, instantaneous response includes elastic and time-independent plastic flow. Creep then proceeds in three stages of primary, secondary and tertiary creep"

according to my research and experience, copper creeps also, particularly fine strande wire. and yes ferrules is the most professional way to do it. i think in some countries, germany for example, there are rules where you have to use them. it is a bit hard to get them though.
chris, look into them ferrules, at the least it will give you another opportunity to use your new super hydraulic crimper and ease worries and sleepless nights. i don't like the screw terminals in the midnite classic at all. for one thing they are to close together. and i would prefer eye terminals or lugs or what ever they are called. with a counter nut.

australsolarier, have you found a good supplier for the Ferrules?
