It does the job. Doesn't it?

You're probably using it in 4T, meaning press the button, low amp HF start arc, as set with the first knob on the top row, release the button, full power as set on the second knob of the top row. Press again and release, arc slopes down.
If you use 2T, the readout will give you the welding amps. Otherwise it's the start-arc amps. Other solution is to set the start-arc and the work-arc amps simular.

I use push locks , and the reg is an old Glore I had around.

- The welding clamp sucks and the cord is pretty short. Will be replacing those.
First thing I did. Made a longer, heavier ground cord with heavy clamp. But I retained the lighter cord and clamp for "delicate jobs".

Verdict so far, Great welder for the price! Will report back with some vids and pics once i have time to really get stuck into it
Got mine for a year, and no complaints. Also, AU$ 683, delivered at the front door.

'Kay so had some time today to set it up and bust out a few welds.
The air fitting is 8mm which is apparently, super uncommon. Had to grab the regulator fitting from the welding shop ($3) and the hose is just some PVC from bunnings
The set current does indeed show up on the meter when you hit the button, so thats good. And the current is set with a seperate knob on the footpedal which is pretty much ungraduated, but whatevs. All is well there.
The only AC setting is balance, it hasn't got square wave settings or wave form control, but it might have frequency... theres a frequency setting for the pulsed mode which goes up to a 200hz, so maybe that can be used on AC mode. still have to check that out.
Welds very nicely on AC and DC modes as expected so happy with that. Boy does this thing spew out some interference though. It causes my radio to have all its channels wiped even on DC mode
I also think my machine needs the spark gap checked. It seems to have a hard time getting an arc going, though that may be my filthy scraps of metal i tested it on lol, none the less, i wouldnt mind cracking it open and having a look inside
The clamp, 240v power cord and torch cable are really blardy horrible and hillariously short too so those are next on my list of things to buy. Also got to have a look and see if i can replace the 8mm gas inlet fitting with a nitto quick change fitting so i can swap the argon and compressed air over super quick.
Rating so far: The accessories are pretty rubbish, but the core machine is excellent for the money. another $300 on top of it to change the cables/torch bits for good gear and you should have a great machine. _________________ www.demon50s.com - Minimoto parts

Once again the Chinese manage to prove there is *nothing* that they cant make a lot crappier and little cheapy-er.
I sa(l)vaged an (suspected chinese) IEC plug cord the other day for a 3 pin plug for a fluro batten. Got plenty of them around since they come with every elcheapo computer or computer power supply you buy.
Dug it out of the cables box, Cut the end off, thought, hmm, this 3 core flex is pretty darn lightweight gauge (about 20 gauge at a guess under all the plastic), oh well, its only driving a 28 watt fluro, Id hate to think what would happen if you actually used it to power a 1000watt Kambrook Kettle or something.
So, strip the conducters, twist the super thin "copper" for tinning, and.. "twing" it immediately untwists again as soon as I let go of it. "Huh ?". Twist, Twist, release, Sproing, untwisted... "WTF?".. Poke at the wires and bend them.. sproing, and they are straight again with not even a kink.
What *is* this stuff ? Its like braided horsehair, but it will *not* bend. Bend it 180, squeeze and release and twing, its dead straight again. It sure as hell isnt copper, Is this stuff even metal ? I half expected it to be some sort of Litz Wire or something, but it actually tinned ok once I left the stripped insulation on to hold the strands in twisted form (which Litz wire doesnt).
I wouldnt want to put any serious amps through it, its like metal coated fibreglass strands or something. Has anyone seen it and know what it is ?
It is actually powering the fluro, so it does conduct, but I was just shaking my head all day.. I mean I know copper is expensive and all and they probably pump these leads out by the gazillions, but cmon, some things you just dont mess around with. Its probably made of Oak Tree resin with copper powder coating or some bizzare advanced copper substitute that saves then 20c per lead or something..
Anyway, good job on the welder inside secret details, Not surprised on the build quality.. I too was thinking about buying one of them, or maybe this model - the taller narrower box with the angled control panel at the top edge - they claim its a "brand name" (that others are trying to sell chinese copies of !) . yeah right, they *all claim that about each other. Be interested to see a tear down on one of these..

Id be surprised if it wasnt much the same though,
Still, if it works, I suppose its not too bad.. as long as you can find the seller in 9 months time if it fries under warranty that is,..
Those guys just never cease to amaze me.. have they no pride or are they just employing people who really have no idea what all these wires and bits do and are assembling them after 5 minutes of looking at a coloring book guide or something ? _________________ Great minds discuss ideas.
