I've got a new Oxford migmaker 240 on order. Its coming upto 9 week wait now, was quoted 3 weeks when I ordered it. Apparently its built, they are just waiting for the case to be made. Im sure its going to be a great welder when it arrives, but if you are in a hurry to get one, make sure you know the lead time on what you order.
Nice one! I found it took a little practice to get used to it compared to my old Sealey Mightmig 130 XT, but it is worth it.
It's only a hobby for me - so I actually weld quite infrequently (hence I expect my oxford will probably last me 30 years).
The limit in the quality of my welding is now totally me, not the welder. But it's now became a good challenge to do a tidy weld, rather than just stick the bits together.

Anyway, notwithstanding those caveats, here's the last couple of things I welded on mine:




Those are 3mm. The main thing that surprised me is I am running the welder on a much higher power than I would have on the Sealey, but then also welding much much faster. (And FWIW, constructive criticisms always welcome)

I got taught to weld years ago at college a heck of a long time ago (MIG/TIG/ARC and Gas) - when I bought the first welder I thought how on earth can I completely forget a skill like that!!!

Is that in a Kit car of some description or a heart transplant on a cradle?

There in a nutshell is the thing I love about the Portamig/Oxford machines - they have a really big working window - you can get bacon frying with a wide range of settings biggrin

My first welder if you didn't get the settings absolutely spot on it was a frustrating task trying to keep a run going - the fact that the power and wire feed changed as the machine got hot made it even worse. None of those issues now. Very happy with my "lifetime purchase"

Yeah - that is so true! Weld one bead - lovely. Next bead - WTF!!! Good riddance to those days.

I'm re-engining the Ultima Spyder I built in 97-99.


Lots to do, but it's a low stress, fun project. Engine & Gearbox mounts done. Gear linkage next.
Engine will look like new once it's all done.

Sounds like fun - Do you have a thread running on here?

When faced with the dilemma, I ended up with an Esab Caddy 160i inverter mig, and reg, from Weld Equip and its been bloody good. It's now something like 8yo and still lovely.

Buy the best you can afford, once.

I'm told Jasic are ok, ditto R-Tech but have used neither.

Thanks for the replies - in typical PH-style I have in fact ignored all of your recommendations and ended up with a Rohr inverter welder which got some very good reviews and is quite small and compact and should be good for about 5 to 6mm metal, which I suspect is far more than I will need. It was also very sensibly priced (although no regulator / air hose) which is good as I won't be using it all that much.

Currently assembling the various pieces I need - air hose, regulator etc.. and a decent welding respirator and I will let you know how I get on with my first attempt at using the machine.

I do recommend SGS gases - you can get the bottles at many motor factors.
Otherwise if you're going disposable, go on ebay and get the big disposable ones, not the little ones that are more common.
Oh, and use a Argon/CO2 mix, not pure CO2. Much cleaner welds.

Indeed, I have a large Hobbyweld argon/co2 mix bottle sitting in the shed now rented from the local motor factor - I used those little disposable bottles before and it would run out every few minutes - hopefully this time I will have enough gas to do some proper practising.

Sounds perfect. I only have SGS because it came with my TIG and there is a local stockist, so it was convenient to standardise brands across both the TIG & MIG.

Thank goodness it's no longer the BOC monthly bottle rental gig.

Just to follow up on this - the Rohr machine is really good for a novice like me - I've managed a few practice welds that look nice and neat to my eye, the wire feed is smooth and all round it's very nice to use, much better than the old Halfords one with the jerky wire feed.

In addition to youtube vids, I'm finding "Fabrication Life" on facebook to be quite an instructional group:
https://www.facebook.com/groups/134779203860936

Lots of experts posting there - but also lots of people whose welds are not unlike mine also post and get good advice.
