good high ocv, id still prefer it to a bzzz box,
I know what you mean but the alternative is likely to be a ban on any dissenting opinion, like mine, so all we're left with is a question about buzz boxes, a few responses that buzz boxes have nothing going for them (wrong in my opinion) and that's that.
I agree that higher OCV is desirable (I have machines with higher OCV) but it's not essential, as I think I've proved with my Wolf arc welder 'buzz box'.
A warning to the OP - this thread is more balanced than some in terms of accepted dogma vs dissenting opinion, BUT only buy a buzz box if you're prepared to also buy a MIG machine later. The buzz box will always be useful for thicker steel and you can keep the MIG just for use on thinner sections. You might get lucky, like I have, using the arc on thinner steel but it's still hard work and not the preferred approach for most people.
so what rods do I go for, a crap rod will in turn give crap results
I've not been persuaded to spend a lot more money on top branded rods.
Nor is it necessary. As I stated above, it's quite possible to buy good quality rods from a welding supplier for less (far less) than you might pay, per rod, from the likes of Machine Mart or Halfords or B and Q, and the like. George, you're doing it again. We're not saying don't buy cheap, just that if the OP does, he will be making life difficult.
I am keen however that this thread doesn't turn into another debate about cheep vs expensive, or the thickness of materials that can (and I'm using the term loosely) be welded with stick...
I am looking to start ARC welding, firstly to repair a hefty couple of joints on a trailer but also some lighter work if I can.
The ARC welder can go as low as 40A and as high as 100A, the torch can accept 1.6 to 2.5mm rods, what sould the thinest and thickest sheets of mild steel I could weld?
Hope someone out there can help, it was Uni the last time I touched an ARC welder and all that information in my head was replaced a decade or more ago.

The only way to ensure quality / consistency is to buy branded rods but you will pay a premium. As with most things in life you get what you pay for.
Have you considered MIG? Can't be anything over 3mm on a trailer and arc really isn't the best process for anything thinner than that.
MIG would be a lot easier for thinner stuff than trying to do a botch with Arc. Something like a Clarke 130 MIG would be fine, and the EN versions can run gasless wire so you can save money on shielding gas (they will also run with shielding gas). You might even get to enjoy welding.
I have to mention I make MIG welders inside an extinct volcano on a tropical island so am completely biased. (I also own the argon mine next door).
Like everyone else suggested if you are daft enough not to go the MIG route pick up an inverter arc with a decent OCV and decent rods. Forget buzz boxes - they are rubbish.
was wondering after reading this thread whether the trailers people make are subject to any kind mot test, not saying that any body here could'nt or should'nt but if random people are buying some angle, welding bits together, loading them with a ton bag of sand and motoring along dual carriage way at 70mph it sounds like it could be a recipe for trouble. Are these home made trailers insured by your car insurance if they fall apart and kill someone?
