Bought last week and arrived on Thursday, been wanting one for years/decades...
A Japanese Daihen OTC AVP300 Accutig inverter, I've spotted slightly older ones selling for £ouch in the far east, this was less than my last meal out with the kids!*
It's 3-phase and "untested, spares or repair" from a reputable welder dealership and was taken as part-exchange on new equipment for a factory (one of about a dozen) - if it needs repair I'm a pretty competent electronics tech...
My phase converter will run it up to about 240 -250 A (if I had proper 3-phase it's capable of a bit over 300 A on AC and DC), which means a water-cooled torch is a good idea (a WP18 and long cables/hoses came from EvilBay too), I'm part-way though building a torch cooler, I'll post as a project eventually.
Some of the Bits from the World's Best Skip to start on the cooler:
Radiator from a water-cooler for Science, pair of 220V fans.
And a case from the same low-cost source, narrowed by 6" to match the width of the welder with most of the parts for a guesstimate-fit, the stainless pan holds 7 quarts and was thrown guess-where when the canteen was refurbished
I need some parts still, so EvilBay will be getting / has had orders for things like QDs for the hoses, meters for the front panel, a warning light or two? Half way through putting together a board to monitor flow rate, return water temperature, and set off a screaming buzzer if it goes wrong...
Still need to get a bottle and regulator, but there's a reasonable deal on rental and refills from a place a few miles away, I shopped around and if I used slightly more than a 20L x 200Bar bottle per year it's cheaper (in the UK) to rent and get cheaper refills than to go rent-free with the hefty deposit and refills at twice the price. How does it work elsewhere, I know that some on mainland Europe have trouble and expense obtaining welding gases?
