I've been wanting to buy an AC/DC Idealarc 250 off of craigslist for a while now, and recently found one that I may make an offer on, but it doesn't have the "C" in the code number which means that it doesn't have a power factor capacitor, right? How important is the PFC (for farm use) and should I wait for one with the PFC to come along? He's asking $600 which is more than I'm willing to pay for one. I was thinking I would offer $400. Would that be a reasonable price? Too much, too little? It looks to be in very good condition (see pics) and comes with some extra 2/0 cable.

Reply:Whether or not you need the PFC installed depends a lot on what sort of power supply you have to feed it. In general, a PFC equipped machine will require lower max input amps to generate rated output. However it's draw at idle will be higher. That is an advantage if you can meet the minimum draw for idle, but don't have as much power available for higher end use.However in some cases you can operate a nonPFC equipped machine at lower amps if you don't need max power. For example a couple of members here have had issues with PFC equipped machines tripping a 50 amp breaker at idle, while other members with nonPFC equipped machines can get away using them on a 50 amp breaker at the lower output settings. If the one had a 70 amp breaker instead, the PFC machine might be able to generate full rated output, while the guy with the non PFC machine might need a 100 amp or larger breaker to get the same output.You need to look at the manual and see what the rated draw is both with and without the PFC caps installed and look at whether you can supply the power the machine requires. If you have plenty of power available, it really won't make much difference. If you have only a very limited amount of power available, you might be better off without the PFC caps as most seldom need to run a machine like that at max rated output anyways for hobby use. Some guys have added switches so that they can take the PFC caps "out" of the equation for use on limited power..No government ever voluntarily reduces itself in size.

Reply:For that machine $600 isn't a bad price. The little cart it's on would cost a $200 to make. I'd guess the seller might??? take $500 cash in hand but you never know. It won't be a hard machine to sell. New ones are about $2500!
Reply:I stumbled on to one at a local flea market last spring and paid $130 for it. I put a $2.00 bushing in the amp control mechanism blew it out good and was in business. I later sanded and repainted the machine and found a used Lincoln undercarriage for it. The one you are looking at appears to be in cherry condition, it will last you a lifetime.
