OXFORD CUTMAKER 550 DUAL VOLTAGE PLASMA CUTTER
The Oxford CutMaker 550 plasma cutter is capable of 22mm clean cut in mild steel. Available with as a 110V / 230V power source or a 230V / 400V machine. Dual input voltage machines are perfect where a machine may be used in more than one location with different power supplies.
Utilising the highly acclaimed Oxford hybrid technology these machines are built with both older style transformers and with the best parts of inverter technology. What does this mean to you and me? Oxford say that the use of transformer technology increases the life span of the machine, making it less susceptible to the ingress of dust, spikes in input power and knocks and drops. In fact, they claim these plasma cutters are likely to still be working well in 20+ years. The addition of newer technology means that the user still benefits from the decrease in power consumption and the fine tuning associated with inverter machines.
Here’s what Oxford says:
“The benefits are real, look at our performance specs & you will notice our machines cut more & do more than all other machines on the market today. And importantly because these machines have a copper transformer & are not an inverter you dont need to be concerned about reliability or lifespan. All inverter based machines suffer from reliability issues, the low cost imports often fail in a few months, even the quality EU or US made inverters do not have a long life & repair bills can be so excessive that the machine has to be scrapped.
Our hybrid chopper design is totally unique, internal contruction is simple with only one PCB fitted, they are not affected by damp or harsh conditions such as dusty dirty workshops, knocks & drops, unstable input voltages cause no harm, even 75% over voltage for a few seconds can be tolerated.
Rugged, reliable machines with the best cutting performance possible from an air plasma cutter! Satisfaction guaranteed!”
Oxford Cutmaker Features:

- Cuts clean or dirty & rusty material just as well, steel, galvanised steel, stainless steel, hardox, aluminium, brass, copper etc
- Thermal gouging function allows the operator to gouge away material efficiently, ideal for removing welds, fastenings, edge plates brackets etc
- Thermal arc heating function allows the operator to apply direct thermal arc heating similar to using gas bottles but using only air & electric!
- Energy efficient design 90%+ efficiency means you get more cutting power for the lowest input power.
- Class leading air consumption, as much as 50% lower than competition means only a small compressor needed & the lowest possible fumes.
- Bullet proof design means this machine will be unaffected by varying input power or unstable generator.
- 20 foot torch for cutting, & thermal heating/gouging, uses long life low cost consumables.
- Now rated to IP23S protection so can be used outside in the rain or in your workshop.
- Built in air filter to help trap moisture & particles with regulator & pressure gauge to allow easy setting of air.
- NON HF design means these are safe for use on vehicles & around IT based equipment.
- Built to last in Great Britain! to BS EN60974-1, BS EN60974-10, RoHS, weee & CE marked!
Lots of options including;
- Torch quick connector fitted
- Longer leads or torch
- CNC interface for cutting table use
- Circle cutting kit

OXFORD CUTMAKER FUNCTIONS
Cutmaker models offer exceptional cutting performance on all metals, only the very best American made machines come close to our cutting performance. When compared to oxy-fuel cutting the Cutmaker is as much as 5 times quicker particularly on thinner materials. These machines also give a cleaner finish and with far less distortion. The Cutmaker series produces a very narrow cut, with minimal dross thanks to a constricted cutting arc. Cuts in material up to 20mm will even be very close to perfectly straight.
Power is infinitely variable in these machines allowing selection of output to suit the material. For thinner materials, turn the output down to give a very fine cut and controlled cutting speed with superb, near laser quality. For thicker materials, output can be turned right up to get the cut done quickly. In instances when a material is double skinned its possible to turn the machine up to cut both layers or turn it down to only cut the top layer.
The Oxford Cutmaker 550 comes complete with a quality plasma cutting torch, which is compact for getting into tight spaces. Supplied as standard with long reach drag consumables allowing the user to keep the torch in contact with the work piece which makes following straight lines and templates much easier and more accurate. These long reach torch consumables offer superb access into places most torches cannot touch, if reguired there are also very short compact consumables available. The torch parts are all low cost compared to other quality machines on the market & there are only really 3 wear parts on the torch, electrode, tip & copper drag nozzle.
Arc starting on the Cutmaker series uses air only and not high frequency (HF). Not using HF means these machines are suitable for use on vehicles and near IT systems without causing damage.
As standard we fit the plasma torch directly into the front on a cable gland which is the most secure & reliable method. Some competitors have a quick connection on the front to allow fast removal of the torch, however these always extend out from the machine by up to 8″ & are often the first part to get knocked & broken. We can fit a quick connector on any model if you prefer.

THERMAL HEATING FUNCTION
Thermal heating is a handy function developed to provide a fast source of heat in situations such as attempting to remove nuts, bearings etc. Thermal heating from the Oxford Cutmaker provides an instant heat, much hotter than gas torches can produce. Heating is also far more direct and controllable, meaning heat is only applied to the area in question. For instance when removing seized nuts propane torches tend to heat the nut & bolt, the cutmaker plasma will heat the nut & leave the bolt relatively cool, this allows the nut to be removed quicker.
In addition the thermal heating function can be used for light preheating applications.
All the OXFORD Cutmaker models have the same thermal heating capacity & duty cycle which is 50% (5min on, 5min off etc).
The following are typical times to heat nuts to cherry red colour. M5 – 4 secs, M6 – 6 secs, M8 – 10 secs, M10 – 15 secs, M12 – 22 secs, M16 – 33 secs, M20 – 45 secs.
You will see this thermal heating function can replace expensive gas bottles for many applications! A video demonstrating this function is available on the Oxford welding YouTube link.
THERMAL GOUGING FUNCTION
Thermal gouging using plasma on most machines is too vicious & the arc has a tendency to cut into the metal rather than gouge metal. These OXFORD plasma models have a soft arc when gouging which is better for removing just the metal you need to remove. The process is fast & precise & the compact torch allows you to get into places where a grinder would not be possible. This is particularly useful for bevelling & metal preparation, removing welds, removing wear plates etc.
Why accept an imported machine when you can buy a top quality British made machine for a similar price?
Every Oxford welding machine is offered with the following guarantees:
