Hello,After looking through all of the various welder generators online, I'm very perplexed as to the answer to this one.I have a buzz box welder (Airco 225A MSM Stinger II). It draws 48A at 240v. I live in the US, so that's 2 circuit breakers rated at 50A or more. That is 12kw (240v * 50amps(I rounded up) == 12kw). When I look online for generators to make my welder more portable, I find that the 12kw generators are literally the top models. The best and most expensive you can buy.But when I look at a welder/generator combo machines, I see that they are all 10kw or less but with equal or even better specs than my buzz box can offer.Are my calculations off for my welders wattage?Are current welders just way more efficient?Thanks!

Reply:Buy a cheap welder, cost 1/3 what engine drive would and genset to power it would cost 1/3 as much.www.urkafarms.com
Reply:For couple reasons but this it a plan to use expensive genset to power junk welder.www.urkafarms.com
Reply:My personal experience, from the 1990's,,,A friend wanted to build a trailer, he had a 5Kw generator, and wanted to borrow my Miller Thunderbolt welder.Well, the generator ran the welder just fine. I think he had to be careful of not exceeding the duty cycle,, (in other words, he could not run too many rods in a row)My first ever welder was a Lincoln buzz box, that was connected to a 10HP Kohler engine.That 10HP engine had no trouble running 1/8" rod all day long.10HP is probably less than 5Kw when discussing a generator, positively WAY LESS than 10Kw,,
Reply:I never really ran them on small gensets.i got a tuff 6k I should try a buzzer on for giggles. Be a little more incentive to do it for dc machine.www.urkafarms.com
Reply:My (29 hp diesel) Miller Big Blue 251D only puts out 26A at 120V (3 kW), but I guess it'll also put out that much power while welding, since they say the generator output isn't affected by welder output. Seems kinda low, but I guess they designed it assuming that all anyone would want to run off it would be some grinders and maybe a light...

Reply:I suspect engine drives must be a little more efficient since they can just produce what you need for welding without worrying about what's safe for a standard outlet, then converting that to what you need for welding.
Reply:I am not sure I understand that but, most engine drives are able to produce wayyyyy more than is typically used (cept for a few) Its been 20 years since I even ran a 5/32 and most done with 1/8. 20 HP is a waste but its not a big deal if a guy is billing for it. You could buy a bit cheaper if u no but today would be looking at that yellow 180 and whatever it took to run it.www.urkafarms.com
Reply:Even cheaper is a 400 genset will run a 300 welder,,, no point in getting 1000$ genset to run a 100$ machine. And 1 so limited at that. AC and single voltage input.www.urkafarms.com

HotEnd,Yes, modern welders are more efficient, but not every single one is generator compatible, even if they are of the newer inverter-based power supply type. My 160A dual voltage inverter stick welder doesn't like my generator at all, and it's pretty clean with Last edited by Sberry; 1 Day Ago at 08:01 PM.www.urkafarms.com
Reply:I would avoid gasoline gensets at all costs. Get a diesel unit they last a long time and sip fuel. Gasoline goes bad and its doesnt go over well with the SSHO to have 20 Jerry cans laying around full of gas while hot work is being done. A gas generator wont last much more then a couple thousand hours (compared to 35,000+ for diesel) and drinks fuel like you wont believe. Its not just the cost of the gasoline its the constant stopping to refill/go get more gas. I have a gasoline welder on my truck and we have diesel units at the yard. The diesel units (Mulitquip)will run all day with 2 guys welding on the same machine on 5 gallons or so and they hold 20 or 25 gallons. My gasoline unit (Miller) holds less then 10 gallons and needs to be refilled multiple times a day.
Reply:Thanks everyone!I consider this question solved.
Reply:My 10k Miller trailblazer 302g generator will run my 350p welder at 25.? Volts and wire. So basically I can weld anything 3/8" with 035 solid wire.It welded 6" pipe bollards to 5/8" plate in the floor.Sent from my SM-S901U using Tapatalk |
