The Oxford I-MIG 330 is a 330A step regulated MIG welder made by British welding machine manufacturer Oxford.  Available as a single phase machine or 3 phase supply spec.  With a low minimum amperage of 20A, these machines are suitable for the thinnest of car panels, to welding steel work to medium and heavy agricultural work etc.

The Oxford I-MIG range are the most heavy duty MIG welding sets in the Oxford range.  Copper wound transformers, rugged switch gear, over rated rectifiers and double fan cooling are all built into a strong 2mm steel chassis.  Preferred by some, a transformer based machine arguably provides very long life spans and great reliability.

230V or 400V Industrial compact MIG welders complete with 4 roll drive. Ideal for medium duty fabrication, maintenance work and medium to heavy agricultural welding etc.


Main Features:

  • British Made
  • Heavy duty easy access wire spool holder for 15kg or 5kg MIG wire reels – a mechanical brake prevents overrun
  • Robust gas bottle carrier, holder and chain suitable for all bottle sizes
  • MIG welding possible of Aluminium, mild steel and stainless steel
  • Easy MIG wire loading – accessible just under the lid.  Simple
  • Oxford Cap + technology – Very smooth weld conditions on all materials, steel, stainless steel and aluminium etc.

  • Simple PCB – Robust for everyday use.  Controls all functions including super smooth motor speed variability, motor braking and burn back control
  • Good range of carefully selected voltage steps – Perfect settings for every job.
  • All machines have a minimum amperage of 20A – weld as thin as you need.
  • Efficient Oxford design –  Low power consumption and decreased running costs.
  • Supplied on wheels and casters – perfect for manoeuvrability around the work shop
  • Industry standard euro connector with all brass construction – use your favourite torch.
  • Built to comply with BS EN60974-1, BS EN50199, RoHS directive, & CE marked.


There has never been a better time to buy British! With the weak British £ Oxford machines are more competitive than any similar quality imported machine & with the OXFORD long term back up buying British has to be the wise choice.

More output power from a 230V supply, lower input power, better duty cycles, better long term support, better pricing & all made right here in the UK!

* 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.
