Powerarc 140 review

[Titan winch]

As I understand it, this new circuit will limit the output to ~100 amps when operating on 110 VAC. With a unit that doesn't have this built-in limit, it behooves the operator not to exceed 100 amps indicated.

It is not quite like that with the old models. While i can not or actually more to the point do not want to discuss the upgrades ( this applies to all dual voltage) as i do not want to give our Competitors the information that we have worked so hard to find for improving this unit by simply reading this thread and having the same upgrade done to there product.
BUT
here is the condensed version . The chances are very strong that there will be no issues with any previous models as the Breaker will trip before causing damage to the unit ( most people max 120v = 30 amp breaker max )
the potential for problems arises when you have less than ideal power sources. For example here in Canada Hydro is supposed to deliver minimum 110v but it has been known if you are at the end of the grid and heavy use etc if your 110v becomes 104v ( this is a example ) then this can cause issues when running on the 30 amp and dialing max at 110v . we have upgraded certain components to 25% more capacity ( trying to be really vague here and still give a somewhat coherent answer ) I would not be too concerned about running it at max on 110v with a 30 amp max breaker although this is a non issue on 220v running on 20 amps drops your max output but also gives more protection to some components .
Can not really say anymore at this time

Can one safely power the 140 st off a quality generator equiped with AVR (automatic voltage regulator)?

We do not normally recommend running on a generator, as there are so many and some have really bad power out.

It should not be a problem, I would use the 220vac. And I assume with AVR you have at least 30 amps output. And make sure it has a nice sine wave out. What is the brand name on the generator?

I have a new powermate 6500 watt continuous 8125 watt surge genset. "Generator manual states "Equipment damage can result if equipment is not designed to operate within a +/-10% voltage variation, and +/- 3 hz from the generator nameplate ratings."

Like I said, we do not normally recommend running on a generator. I am not up on the 140ST PS design, so probably not worth the chance.

[performance]

It should be less than 10% for that unit.

What should be less than 10% for which unit?

I know this thread is a bit old but I was wondering if there were any conclusions out of this:

is the amp readout more accurate from units currently shipping?
any additional advice for using a generator with this unit?
has the size issue with the dense connector been worked out?

Trying to save up for one of these units ... don't want any issues to break my bubble at this point!

Thanks!

I own the Power Arc 200 and 140st. I bought the 140st for the price and I used one of the Harbor Freight inverters for small stuff around the house 110v. I wanted a small unit with a tig torch as well. I use my Power Arc 200 of my generator for mobile welding (I have 50' leads). I always carry them both on jobs, you never know! One I use for heavy duty jobs, and the other I use around the house, but both have performed well.

Hey i had a buddy with a mobile welding service really sucked he was welding on a roof and his welder and stuff was in a trailer . sorta his fault he left his keys in his truck , was welding stopped and took alittle break then went back to welding and had no power looked down off the roof his truck and welding trailer was gone . all there was to long leads laying in the parking lot . thank god they caught the guys that took his truck . so to say he dosnt leave his keys in his truck anymore lol

After each hurricane season you will hear that about roofers. I was on the roof, then my generator stopped. Went to check, ladder on the ground, truck/trailer or trailer gone. Now with cellphone, things are better. Imagine way back. Sit on the roof until the customer comes home. Or wave hands are cars going by if close to the road.

I purchased a HF 80 inverter a month ago. As I can't weld indoors, I was only really able to test it last week as it rains just so much in this area. I pretty much had hoped it would get my foot in the door so that I could learn stick welding and be portable. Unfortunately, I had to return it as it failed on me. Now trying to save up for the 140st as the HF 80 left a bad taste in my mouth. Really has me paranoid now as I don't want to invest in my next unit and have it unreliable. Great service from HF though. Very good return policy.

I visited your website. Nice helmet! I've got the same one but really, it is the only one I've every used so I don't know if it compares well with other helmets out there. Congratulations on your studies. Hope you've graduated or will soon.
