I am going to have a look at those oxy petrol sets tomorrow, they say it’s for cutting and welding but I don’t see anywhere one with a welding torch, I want to get one for when I run out of carbide for the acetylene generator witch is going to be a long way off still as I have almost a full 44gal drum full.

i just brought that same one haven't used it yet but it looks like junk straight out of the box, may return it for the boc one for similar price, the hand piece on the tool shed one looks really chinise and the consumables look rubbish. but the tool shed one does come with a 3? year warranty 

Yeah I bough the same one, tbh not overly stoked with the appearance but the specs and warranty seemed good for the price so going to give it a go. 

I've never used a plasma cutter before, how do you know where to set the air pressure? The manual has 65-87 psi (4.5-6 bar) but that is a pretty massive variance and seems to be pretty hectic pressure, even at the low end, but that may just be because I haven't used one, but it throws a lot of sparks.

Cheers, Pyrex = borosilicate glass = what I sell

If you do decide to start making them I will grab a few from you. Just learning at the moment so am sticking with standard consumables for cost reasons. But need to get some in the future and would like my money to stay local,

I'm looking at getting a new mig soon, I want something in the 180-200a range. Budget is around $1k though could stretch if needed. Would prefer reliability over having bells and whistles. I already have a old hf start ac/dc tig so it only needs to mig, though most stuff in the price range seems to be multi process. Currently thinking this is at the top of my list:

though at a bit of a stretch there is this:

https://www.boc.co.nz/shop/en/nz/welders-plasma-cutters-torches/welders-wire-feeders/mig-mag-welders/boc-smootharc-181-mig-welder-boc181mig-p

which has much better duty cycle, but doesn't appear to have adjustable voltage. I have never had adjustable voltage so don't know how that works. Probably just another thing for me to adjust incorrectly.

Any suggestions?

I've got the BOC 181, seems to work fine. Single knob makes setting easy.

I use Pyrex cups in hard to see places, they are all good. 

Probably a real obvious answer, but how come you only use them in certain situations and not all the time? When i was messing around with a TIG it seemed like a good idea being able to see better.

I only have them in one size, and I don't think the gas flow is quite as well optimised as a conventional cup.

 

Ideal for aluminium where you need minimal stick out, and to be honest I'll often just leave them on for stainless etc..

If it works, sweet. If it doesn't, good luck getting any service from them. Going by the feedback. So long as you're happy getting what you pay for, it might meet your expectations. Otherwise you may regret not spending more and getting a longer locally supported warranty. 2c.

My new mig witch I have used about 4 times has had about 4 different gas leeks, fixed them all but now the valve in the torch is leaking, never come across one with a valve here, I think spatter finds its way into the valve.

Need to see the label on the back of the machine, but the time period for the duty cycle rating will be super short. Most welder duty cycles are based on 10 minute blocks. This machine will be something like "100% @ 232A" based off 1 minute blocks. 

I also highly doubt that a 13.2kg single phase baby machine like that is capable of outputting 300 amps.

Oh, follow up on this. Got the BOC smootharc 180 multiprocess. I really like it, welds very nicely and the cooling fan only comes on when it needs to so its silent most of the time.
