I have welded with an -002a and -003a quite a bit with no problems. You'll be pushing the -002a for the bigger welding jobs. I haven't stick welded with either machine, but I have run MIG, TIG, and flux core on both. My small flux core machine runs fine on either machine without difficulty...

The -002a/-003a run fine on WMO. I have a centrifuge setup that I have been using for a few years. Initially I installed it to clean waste oil for running in my other non-highway equipment, but I discovered that purifying the oil with the centrifuge also cut down on the maintenance/cleaning...

This is how I deal with my surplus waste oil...most often during the summer when my furnace isn't consuming enough of it. But I don't parallel my generator with commercial power :) When I need to get rid of an extra 20 or 30 gallons, I just switch over to generator power and make sure I have...

Found a good pic of a synchroscope similar to the mil ones we used:

Your edit is correct; the 2 lights are kind of an assurance that both generators L1 L2 and L3 are wired the same internally and externally (i.e. rotating in the same direction). It is possible to have one output in phase with the other two out of phase if the 2 sets aren't wired the same. But...

EXACTLY. Frequency does increase very slightly if you open the throttle of one generator (not visible on the analog meter, but measurable by a DVOM). What Triple Jim says is correct; once the 2 generators are paralleled, it is nearly the same as if they were mechanically connected. It...

Yes, the output frequency of the pair will increase slightly. However, the load shift is what is primarily accomplished when opening the throttle. It takes very little throttle adjustment to shift loads from one set to the other... Yes, 2 lights are required for 3 phase paralleling. Much...

Intelligence required, yep! I'd say the dangerous part is mostly in the setup. If you aren't paying attention you could have live cables exposed to human touch. But, once set up properly, I don't feel that there is too much risk. Even if you mess up the paralleling, the worst thing that...

I knew this video would generate a lot of questions like this :beer: Really, there is no good reason for one generator to carry more load than the other when the sets are this small. But, if the load was unbalanced when you first paralleled them, you may need to make slight adjustments with...

The next time I get a set of -003's in I'll do the same video. I can put more than enough load on them to really put them to work.

I have occasionally seen the question come up here, "Is it possible to wire my two -002a's together to double their output?" The answers range all over the board...mostly good information, sometimes the answer is a flat out "no." But I haven't seen anybody actually post a "how to." I have a...

Glad you were able to complete the conversion! I never did get a video made of the CT mod/resistor placement. But, I don't really feel like one is necessary. The procedure is fairly simple; you just place 3 resistors across the 3 CT outputs. Anything between 38-50 ohms would work fine...

Actually, he was quoting me when discussing the jumper...and it was actually my typo (see post number 40). My post should have read " cut the buss bar that connected T10, T11, and T12 together and ran the jumper from T12 to T2" I would correct it, but it appears that I cannot edit a post that...

Coarse adjustment is accomplished inside that black box that I described in an earlier post; most of them are labelled "frequency transducer" on the top of the case (but some are not). Completely removing it and wiring to household current and adjusting for 60hz as PeterD describes is a good...

1-2hz droop from zero to full load is normal. I'm sure there's a spec for it but that will be close enough. If you go for too little droop, you will experience hunting and surging, too little droop and the frequency will drop off too much as the set is loaded. The frequency knob is present...

Frequency is controlled by engine RPM. Faster the engine turns, the higher the frequency. But...didn't you determine that you had a 400hz unit? If so, then it could not have been re-wired to produce 50hz...not without changing the entire generator head itself. The current transformers are...

That knurled knob adjusts droop (how much RPM/frequency drops off as the set is loaded). You must have had some sticky linkage inside of the injection pump that was freed up by moving that knob... The difference between your actual voltage and frequency is a common problem...most of the sets I...

Nothing controls engine speed, beyond the throttle arm and the governor arm on the injection pump. I have seen lots of governor linkages that were not safety wired to anything...they seem to still work fine. But, movement of that arm does affect engine speed. I would start your set up, run...

So your set is running at idle...let's correct that before going any further! A diesel engine may not exhibit surging if it has a fuel delivery problem...in fact, it often times will slowly idle down until it dies. You said it seems as though the throttle arm is moving through its full range...

You are correct; frequency will be the same at the convenience receptacle and the output terminals. You can measure it at any of those locations. Remember that the main breaker needs to be closed if you want to measure output at the terminal lugs...for that reason I recommend measuring at the...
