The Oxford S-MIG 270 is a British built 270 amp MIG welder with separate wire feeder, available with single or three phase input voltages.  Designed for industry, the S-MIG range are built to be robust with an almost unbreakable wire feed housing an all metal geared wire drive system powered by a powerful 90 watt wire drive motor. Standard to the Oxford range, the S-MIG has a substantial copper wound transformer fitted with robust rotary switches.  Metal shafts on switches and an overrated rectifier are also used to provide maximum durability.  All this from an industry trusted brand name, Oxford with a British built heritage dating back over 50 years.



Oxford have spent time to consider common issues with competitors MIG welding machines and have addressed them all with the S-MIG. They have designed the machine to have a synergic control.  Once wire feed speed is set, changing the voltage setting will change the wire feed automatically and no further adjustment of the wire feed speed is usually necessary.  This makes set up of these machines extremely easy and fast too.  Should you need to change the wire feed speed, you can as required to get the perfect setting.


The Oxford S-MIG wire feed units have been specifically designed to stand the test of time and abuse. Ideal for taking into confined environments such as trailers, containers etc and keeping it close to you during welding.  Conversely, the wire feed unit is equally at home on top of the power source, where it fits neatly into the top tray or on the optional swivel.  Bolted on top of the machine, the Oxford S-MIG is very compact,  marginally larger than a compact welding power source.  The wire feeder has a compact and strong design, with the wire feeder cables very securely fixed (pull tested to 200kg).  Furthermore, the wire feed unit itself does not contain any electronics to fail, with the PCB fitted in the power source for best reliability.  All metal construction feed systems contribute to the robustness of the S-MIG wire feed unit.

Extremely electrically efficient, the Oxford S-MIG has been made to provide low power consumption.  Running costs can be kept to a minimum with standby power as low as 25 watts and main transformer efficiencies of 90%.



The Oxford S-MIG 270A has specifically been designed with light to medium fabrication, maintenance work and medium agricultural work in mind.

* 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.  Good things come to those who wait with Oxford machines.  Lead time really varies depending on the factories workload 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.
