Looks like it's discontinued. Has anyone ever used one?https://www.jlconline.com/tools/powe...d-tig-welder_o
Reply:I remember when they came out 3 yrs ago or so. They were insane expensive and pretty limited as far as output and run time. Probably didn't sell very many so they discontinued the product.
Reply:Will it do carbon-arc gouging?  I've always thought of "cordless welders" about like "cordless outboard motors" or "battery-powered locomotives"... neat idea, but, well...

Reply:for serious repair work they're not up to snuff, but ive used the fronius one a bit and for repairing a bit of handrail 10 floors up or small things like that they're handy as, not worth it for home use but say you do quoted repair work they can be a huge time saver.Last edited by ttoks; 12-09-2020 at 12:50 AM.
Reply:You're better off putting together your own power source on a rolling cart, like 2-3 cheap SLA 12V/100Ah batteries coupled with a pure sinewave power inverter feeding a lunchbox inverter stick welder, aka a rolling generator/welder.3000W Pure Sine Wave Inverter $3553000W Step-up Transformer $8012V/100AH SLA batterySay 3 batteries ($450) the voltage converter and sine wave power inverter, that's $885.Yes it'd be heavy, yes you'd be in it for some money, not even including the welder, but hey that's only another $100 at today's Amazon prices for a lunchbox stick welder like my Tooliom 135S.  So for $1000 (not counting perhaps a custom rolling tote/crate that needs to be fab'd up) you could have a battery powered welder that could pay itself off in a few jobs.    So who's gonna make one?  1st on WeldingWeb to have a scrolling sig!

Reply:I have a brand new one of these. https://www.amazon.com/Tripp-Lite-In...744789448&th=1Been wanting to install it in my Van. 3 years later it is sitting on the shelf still. The guy's run 4 1/2" grinders off from these little units just like plugged into utility power. Of course you can't run long without the vehicle running unless you install more battery. Never tried running my Mulitimatic 200 off one but willing to bet it would power it. Make a portable multi process easily on a cart with a few good sized batteries and have mig, tig and stick capabilities. The suitcase style case of the Multimatic 200 is designed for mobility.  Haven't run stick off it but the tig arc is just about as sweet as my Dynasty 280. Even at lower settings it does awesome.Last edited by danielplace; 12-09-2020 at 10:56 AM.
Reply:What happened to the good old days of using jumper cables and truck battery. If you had to takeout battery out and move closer to work.Dave FYI I have 10lb tube of rod for field welding for truck.

Reply:The Hobart cordless welder has a welding time at 180 amps of 2 minutes.Maybe back to old days gas power may work longer.I have had few times I wished for some like this but you do need a longer battery life Dave  Originally Posted by OscarThey got left behind a long time ago.....you may want to pick up your pace and keep up with the group, or you'll hold us all back

Reply:I read the manual on the Hobart that Hobart printed.Dave  Originally Posted by OscarWhy do you think I did the math for you already?   Three 12V/100AH batteries in parallel should be able to provide ~3.5 kW for ~25minutes, minus efficiency losses from the 12VDC→120VAC inverter and the 120VAC→240VAC step-up converter, so you should be able to get 3kW for about 20 minutes.  6kW for 10min.  That would support 180A at no higher than ~26V arc voltage assuming 80% welder efficiency for 10 min.  Next question!

Reply:Not sure what your getting at.  I'm not saying what you're saying about the Hobart isn't true.  My analysis was not of the hobart you mentioned, it was of the setup I depicted as an example. 1st on WeldingWeb to have a scrolling sig!

Reply:I wish for a good price cordless welder. But battery would so big.At times I only had mig welder and do the stick welding so needs to build a small gasoline power mig welder. Dave  Originally Posted by OscarI have no idea what you're talking about.  Sorry, I wish I could converse with you, but you do seem to not care at all how well you carry written word.Not any faster than the time it takes for someone to come up with a scenario where it's application isn't suited for in the first place.

Reply:Originally Posted by danielplaceBattery doesn't have to be big. Just expensive as heck. I build Lithium battery packs and these things have some serious power in them. They aren't heavy like lead acid, gel cell or AGM.Engine power without being able to get away from it would be limited use. If it was super compact and portable and able to be split in two to separate units power source from feeder then you would have something.
Reply:Only thing I was ever able to weld with an automotive battery............................was the battery to the lid of the battery box when the rubber insulating mat moved, and the posts made contact with the battery box cover.
