From what I understand a 25 10/3 stranded SOOW wire for power to Hobart 190, with 30 amp breaker is plenty big enough.Specs are 130 amps @ 21.5 volts 30% Duty cycle.This is the wire specs: SOOW 10/3 Cable - SOOW Jacket, 30 Amps, 3 Wire, 600v - Water and Oil Resistant 25I dont think 8/3 AGW is needed correct?Just wanted to double check before ordering wire. :-) Cheers, AllenLast edited by abosely; 1 Week Ago at 02:46 AM.
Reply:I would personally choose 8/3 to minimize voltage drop IF the machine is going to be used near it's top-end output frequently. But 10/3 should be fine if you're welding at low-medium output.

Reply:The 10 is 2 sizes better than the machine needs and will run a machine 2x its size. Its ideal for this. I would personally choose 8/3 to minimize voltage drop

Reply:Most 10 gauge is 30 amps.But you to provide more details your welding. Odds are it will work great.My welder takes a 20amp 240 volt and I use 12 gauge wire. Dave Welding is base on duty cycle witch most are lucky to MIG weld 40% time. Stick welding is about 20% of time. Dave

Reply:where did you guys learn to size wire and pipe and load demand??????
Reply:OR you could look in the owners manual. Because of duty cycle that welder only requires 14 gauge conductors up to 67 feet from the breaker. 12 gauge would be fine, 10 gauge is a lot of overkill, and 8 gauge is ridiculous.

Reply:Not that it couldnt be done better but they really understand demand and know any more wont make it any better.

I rarely follow minimums, have never wired a 210 with 14 but found out they run just dandy with a 12 at a reasonable length.Last edited by Sberry; 1 Week Ago at 12:52 PM.www.urkafarms.com
Reply:Thats a big wire for a short distance, really depends on are you welding at near max amps for long time?We've done so much, for so long, with so little. Were now qualified to do anything with nothing !

Reply:The only purpose of a breaker is to protect the wiring,, you might as well help the breaker do its job.

Reply:Absolutely correct about the permissible downsizing due to duty cycle. What it doesn't mention, however, is that the same permissible downsizing that aims to keep the wire safe from over-heating, doesn't take into account any consideration for voltage drop going to the machine; it's sole concern is the amperage because that is what heats up the wire. However, welders like high input voltage and they like for it to be steadily fed in.
