Do any of you have any thoughts about this?? I am looking for a way I can get 30-50a draw on 240v to get a good load on a generator (specifically the engine, not the electrical system). I have heard of people warming up welding rods by shorting them out. So that brings up the question - is there a way I could rig the welders circuit with something (not necessarily welding rods) to get me in the range of electrical draw I am trying to get to - without damaging the welder? I'd like to be able to let the rig run for a period of time - as in beyond just burning a few rods. I did test a circuit once using 2x 5/32" rods welded together so I could crank the amps up on the welder. However, the burn time on that isn't long enough and that seems like a lot of waste - rods and metal the beads are on. For reference the welder I am looking at using is an Idealarc 250 AC/DC (1966 MY, round top).

Reply:What about making a homebrew saltwater load bank? You'd be able to dump a LOT of kW of power into trying to boil that water...not sure what it might do to your welder or generator, though!https://forums.mikeholt.com/threads/...oadbank.46075/Last edited by StandarDyne; 1 Week Ago at 11:58 AM.
Reply:I am sure all these schemes would be easier or simpler than finding a resistor? Easy way would be to wire it to a heater element, even water heater.I did test a circuit once using 2x 5/32" rods welded together so I could crank the amps up on the welder.

Reply:He wants to clap out the welder so it won't work right welding overhead.
Reply:If the OP is looking to break in the engine and welding side of the Gen head and it's a Miller, he is in fact one of the few that actually read the manual. You can run on a load bank or weld at 200-250 amps for a select amount of time. Four hours I thought it was the last time we did a new Big Blue 800 dual.
Reply:If you have an electric range at your location, this makes a very good load bank for testing gen-sets. Bob
Reply:good idea, I was thinking oven, trying to put a finger on it but the range idea is perfect. Could turn any n umber of burners on. You should get the big bucks for that one.www.urkafarms.com
Reply:The cheap way is a homemade salt water load bank in one or more 55 gal drums. The less cheap way is resistive heating elements and fans. Of course, the premium way is an actual load bank.I don't know the OP's purpose in doing this, but when you test diesel gennys, they need ran under a load to prevent wet stacking.
Reply:Thanks for the replies.No, the unit is not a Miller engine drive. The generator is a 15kw unit that has a Honda GX690 engine. It is new to me (and never ran from the previous owner) and I dont have much time on it. I want to say it ran for about 6 hours last summer.The issue with the generator is even if we were to run the whole house off of it there wouldnt be enough draw on it to really load it to get it up to temps. The ~6hr run last summer was an attempt tp break it in while running out camping, of sorts, but that was essentially running with next to no load.Engines need to be loaded. 20hrs is the break in period and the 6hr very little load I ran it with wasnt a good enough "break in".If we had a power outage where the central AC was running a lot then that would be a good time to break in - as the AC would draw a decent load. However, even central AC running (not start up) would be a light load for the generator. If I ran both the central AC and electric clothes dryer on high together that would get me in the range of load, but the AC cycling would mean start up load on top of the dryer - and the start up load of the AC may be higher than it can take (50a breaker and the engine does have enough power to drive through the breaker tripping I believe, though I have not tested that - I can at some point - and the welder set to high amperage can get up that high on draw). Im just trying to come up with a more controlled method. We dont have an electric range so that is out. The only 240 loads we have are central AC, clothes dryer, and welders. And Id like to get what ever method off the house - just between the generator and load.
Reply:Honestly, you'll just shorten the life of that generator. Motors shouldn't be "broken in" under load. The manufacturer recommends the opposite

Reply:With 6 hours of runtime on that 22hp motor, one of two scenarios has most likely already happened. Either:a) the motor is already broken in, orb) the cylinder walls have glazed and the rings will NEVER properly seat.If it doesn't burn oil, then the rings have seated and the motor is broken in.If it DOES burn oil. then the cylinder glazed and/or the rings got jammed up with carbon before the rings seated.I think the OP is probably making a tempest in a teacup out of this.

Reply:Generac Home Standby machines are supplied with a proprietary break in oil you leave in for an extended period. No mention is made of any out of the ordinary break in procedure other than that.An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.
