Friends all welcome. Taking this opportunity, and it had to be replaced in its socket extension cord, I want to tell and show in the photo which must be carrying an extension cord for welding inverter.
I have to say that the power strip I in operation for 6-7 years until all excellent, although the rules of the maximum of its operation must be 6 years old, can not remember where and when it is read, but the number memorized.
Extension cords are made of copper and aluminum conductors in the insulation. How long will-just do not tell that to paint the copper wire is much preferred over aluminum because aluminum has greater resistance (respectively, for the same current it must be thicker than the copper to 40 percent, although it cheaper). It is less elastic and reserve extension bending cycles a lot less.
So we will consider the copper cables, which also come in several types, consider 2 types of the most popular, is the cable kg, and PVA
Their differences in insulation copper conductors cable KG rubber insulation, and insulation PVA is polyvinyl chloride (soft plastic). Cable KG better and more expensive, it is more flexible at low temperatures, but the cable PVA in the cold will not be soft. I carry out PVA, just at a time when I acquired, possessed all the full information about him, Now I would have bought the CG, although it only deficiencies in flexibility at low temperatures, but otherwise without difference.
Now a few words on the cross section of the copper wire. Our domestic welding inverters, basically, there are between 140 and 200 amperes. These values should be fine cables of 2.5 mm square, less is not worth taking, and is no longer appropriate.
Socket I put a rubber pad 3 16A / 220V outlet. Block is mounted on a wooden bar. I'm used to wind in the carrying of large rings, so it is convenient to carry or hand, or hanging on his shoulder.
my carrying a length of 25 meters, it is quite comfortable for the length of the welding field work. Just do not forget that before operation carrying must be fully unwound, that there were no rings, or if it does not unwind, then it will be very warm. Here are a few photos and a short text I showed you another a tool which I use for many years.
