Thread: American made AC/DC HF device for welding aluminium (contains 240v wiring)

Hey guys i purchased this AC/DC high frequency device from a guy on ebay called Heward this is the second generation device there is now a third generation device just released a week ago (i purchased mine around 4-5 weeks ago)

its pre-built but will need to go into a box as it contains 240v wiring, it comes with everything as pictured from the seller in the USA

it cost $145 delivered and took 4 weeks to ship over

looking to sell it for $145 including express shipping anywhere in OZ

just after i bought this device i bought a commercially made AC/DC Tig welder

here is the newer 3rd generation on ebay https://www.ebay.com.au/itm/Arc-Star...19.m1438.l2649

trying to upload 8 pictures 4 of the device and 4 of instructions, this device basically turns a old AC stick welder into a AC HF Tig welder for welding alumininum

Hi frequency attachment units are not a new thing.

These were units available as an accessory for the CIG AC Transarc welders many years ago in the 60's & 70's.They were sold complete and just needed to be plugged into a 240V GPO and connected to the welder output. They were re badged Miller units to the best of my knowledge.

Yeah your right GC i had one of the old HF boxes made by Ashton i think it was Australian made they are hard to find i think from memory i sold mine for 250 buxs

I was going to keep this little device for a rainy day but have decided if i sell my other AC/DC Tig machine i'm going to upgrade to a new Bosweld AC/DC from bunnings

I don't understand why you keep changing welders all the time, the one you have now isn't that difficult to use.

I get frustrated quicker with the settings than me typing it each time someone ask's i don't weld every week so when i learn one of the settings i forget it along with everything else just like today i was welding late this afternoon i made sure not to touch my dials and everything was out of wack i stayed calm this time and figured it out after a couple regrinds but my mig only has 2 dials not 8-10 i eventually got the right settings and had to pack up, hope that explains it

You could write the settings down in a book for different material types/thicknesses. Most of the dials will stay the same, mainly just the amperage you will be changing. You could even use a paint pen and mark the dials on the welder, so if they happen to move around you can put them back to the right place easily enough.

That is an idea i have thought about doing i guess i just never get around to doing it, a labeller would be good at the moment i try not to touch the settings or move the machine this goes for the tig and mig but i know without labelling i will be back on here asking for settings again
