Lincoln 305 AC Power

[Aaron Moberg]

Can anyone tell me if the Lincoln 305 and Vantage welders auxiliary AC power is independent of the weld output?

Back when I bought my Trailblazer, one of the points I liked was that the auxiliary power was independent of the weld power. On the Bobcat, the auxiliary power voltage was affected by the amperage adjustment control. Two separate generators - one for weld power, one for auxiliary power.

There is not 2 separate generators like the Miller. Available aux power (10,000 watts) is reduced when welding. When at 250amps, there is 2200 watts of AC power still available. At 150 amps, there is 5600 watts of AC power available. Any questions of the 305, Pm me. I have 2 of them.

Kinda thought it was obvious, the more weld load power required, the less auxillary you'll have. Your Trailblazer was the same way, while a 8000 Watt generator, only 3500 was available at 250 amps welding

I do understand about less aux power being available when welding but if I understand the issue correctly, the trailblazer has two generators independent of each other, the bobcat and others have one generator. I was told by the LWS when I was buying that the bobcat aux power voltage varies according to the setting of the amperage control. With the trailblazer, it doesn't matter how the amperage is set, I get the same aux AC voltage.

Ahh no as I stated, Aux varies with the welding load. Doesn't matter if its 2 separate windings or one.

As for the Bobcat thats a completely different kettle of fish, as it is not designed for a day to day welder. You have your auxillary and you have your weld. Same kinda idea though.

To ask a different way - I understand that the machine can only put out so many watts and that is affected by weld output. But does voltage vary according to the amperage settings?
If I am not welding, only using aux power, if I crank the weld amperage control down to minimum, 10 amps or whatever, will the voltage for the aux be different than if I crank the amperage control to max?
On the bobcat I was told yes, it is different.

[cruizer]

If your not welding then yes, you have full auxillary power. Zero to do with what you have your machine set to.

A Bobcat uses no circuit boards so the auxillary is dependent on where the local control is set to. Like I said, the Bobcat series, has a totally different way of doing things.

No on they run full power no matter what the dial is set at. When I was using the vantage 400 I left it turned down, ran of remote, all the way and still was able to use my grinders.

[Aaron Moberg]

Got it! Thank you!
Typically on a job I'll have one welder with one or two helpers using aux power. I didn't like the idea of my tools getting too much or too little voltage depending on many amps I'm welding with.

Have you decided a machine yet?

[atc250r]

On any decent machine (maybe not Bobcats!), AC voltage will be 110-120 (within 10%), no matter where your amperage dial is set.

Thanks, wanted to make sure.

I'm afraid I'm kind of going back and forth now. I was pretty sure about the Pro300 but a couple people on the forum here were kind of insistent that I ought to consider the Lincolns, that I'm considering trying one. I'd like to get the Vantage 400, I really like the idea of all that aux power, but I may end up getting a used 305g. Really not sure.

get a pipepro350.....................

I will say this tho I've used a pro 300, vantage 400 and 305g. The vantage and 305 are the better machine I would have to say if you are doing any pipe welding. The arc on then is more forceful and more suited for it then the pro300. But then again is the guy holding the stinger not the machine, that makes the weld. When put side by side with the 300D the arc was the same on the vantage and 305g.
