The Oxford MIGMAKER 251 is a single phase 250A step regulated MIG welder made by British welding machine manufacturer Oxford. Updated for 2023, the MIGMaker 251 still offers the same robust British built build quality as before, but now has a more electrically efficient transformer to comply with latest regulations.  Reverse polarity now comes with these machines as standard meaning gasless wire can be used if required.


Welds up to 8mm and down to very thin material too, with a lowest amperage of just 20A.

Will work from a 13A plug up to 65% power.

A popular machine in the Oxford range, great for automotive work, gates and railings and light to medium agricultural work etc.

Supplied with 3m MIG Torch and Single Stage 2 Gauge Argon Regulator


The Oxford MIGMAKER is made with a copper wound transformer, rugged switch gear, over rated rectifier and fan cooling all built into a strong 2mm steel chassis.  Preferred by some, a transformer based machine arguably provides very long life spans and great reliability.  The MIGMAKER range is the most popular model of the Oxford offering.

A high torque cast aluminium wire drive system with a 70W drive motor provides smooth wire feeding hour after hour, day after day.

Oxford take pride in making every machine by hand using the best components sourced in the UK wherever possible.

Updated in 2023, the MIGMaker 251 now complies to BS IEC60974-6 for greater energy efficiency than the previous model.  The transformers are now made to be extremely energy efficient and the machine will draw just 25 watts on standby.

Model Oxford MIGMAKER 251
Amps range 20-250
Duty cycle @ 20% 250A
Duty cycle @ 35% 180A
Input fuse (slow blow) 16A*
Welding wire 0.6 – 1.2mm
Min. Generator Size 5 kVA*
Voltage Steps 12
Approx. weight 60kg


* Note the input fuse size on single phase models is a result of Oxfords calculations & tests, it is possible to use any of these models on a lower fuse size at lower welding power. It is recommended always using a ‘D’ type circuit breaker to avoid intermittant tripping & in some instances you may experience intermittant tripping if using close to maximum settings. *The min KVA rating quoted is for up to 3/4 power output, to achieve max output we suggest increase KVA by 40%.

Why accept an imported machine when you can buy a top quality British made machine for a similar price?


Please note:  Oxford machines are built to order and may take 7 – 14 working days from order to be built and dispatched.  If you place an order online, one of sales team will be in touch to confirm delivery time scales.  Also note our returns policy for these machines on our terms and conditions page.



We have been supplying the Oxford range of machines for a very long time now.  They are just simply built to last!  You just know that you can go to these welders, turn them on and away you go.  Oxford parts availability is some of the best out there too.  Also, in the event of needing technical advice, you can talk to the people that designed and made the machine!
