When I bought the cable, #1 is about $2/ft, I got red and black leads.
(the Idealarc weighs 800lbs so rolling out into the driveway is not an option). I have 25' #1 cables on my Idealarc 300, with quick connects on the end so that I can snap in another 25' extension if I need. And like someone says, the gauge will depend on the length of the run. On the day that you need to weld under a trailer out in the street or set up a swing set in the back yard, you can make up a 220v extension cord and drag the welder out to the job. 25' Welding leads, #1 gauge will probably reach every where in your shop. Even on a cart, do you want to be pulling it around the shop every time you need to weld? But welders are heavy and clumsy, even small ones like yours. It's much cheaper to put a long power cord on a welder than it is to buy long leads. Welding cables run low voltages and huge currents. And, of course, the longer the run, the thicker the conductor has to be to supply the same current.
Which is why power transmission lines run at extremely high voltages. The lower the voltage, the larger the conductor has to be to push the same amount of power through a line. These units typically come with 12' #4 gauge leads, which are too short and too small a gauge. Fact is you probably would have had to even if the original cables were still attached. You got a great deal! But you are going to have to drop some money on cables. Do not go over 30ft use #2 welding cable[too long will cause voltage drop = hard arc staring.Īlways lengthen the input power cable, not the output welding cables on Transformer type welders. It will pop that if you weld more than the duty cycle of the welder Also, you need to use a #6 input wire size. I had to install a 60 amp breaker to weld up to 225-250 amp. Mine will trip off a 50 amp breaker, if I weld over 145 amps. You will need a to wire it for 240Volt-60 amp input. Base on how expensive new welders are today, YOU GOT A GREAT DEAL!. They are very tough welders that give long touble free service. They were made in the 1980's, and yours looks to be in beautiful shape, used very little. You have 2 AC ranges- LOW & HIGH The LOW range has more arc volts for small rods, and hard to run AC rods like Low hydrogen 7018, stainless and hard surfacing. Tim: I have the same welder, tho mine is the Cetury 250 Amp AC-DC output. I found a Century 220 volt 295 amp arc welder at a yard sale sans the leads for $50.00,
