Oxford Tigmaker 220E AC/DC Tig welder
The Oxford Tigmaker 220E is The latest AC - DC TIG welder featuring the latest copper transformer & Mitsubishi PWM hybrid chopper technology,it combines the best of both to give you the performance & efficiency of a good inverter
based machine but with the ruggedness, reliability & lifespan of a conventional transformer machine.
These models are based around the technology used in our highly acclaimed CUTMAKER PLASMA machines. This is our OXFORD HYBRID technology which uses a copper transformer & Mitsubishi PWM hybrid chopper to give infinite & precise electronic control of the output. Chopper based welding machines have been around for a few years but only on the most industrial equipment, we have changed all that. Our chopper technology is a hybrid between inverter & transformer technology, it combines the best of both to give you the performance & efficiency of a good inverter based machine but with the ruggedness, reliability & lifespan of a conventional machine.
Whilst maybe not quite as light as an inverter the other benefits far outweigh. These machines weld as well as the very best German made inverters yet tolerate real world conditions such as grinding dust, moisture, knocks & drops & overvoltage spikes on the supply without problems therefore you can many times the lifespan of European or American made inverters & without the big expensive repair bills associated with complex inverter machines!
Ideal for all applications, they are equally happy working outside in the rain, in the back of a van or in your workshop.These are real ‘go anywhere weld anything’ machine & will run from a 230V 13A plug to around 170A output. Perfect for welding all types of metals, aluminium, aluminium alloys & castings, steel, stainless steel, hardox, duplex, copper, brass, titanium, etc.

DC TIG performance
On DC TIG the high OCV guarantees instant arc starts & is perfectly smooth, stable & quiet right through from min to max power. The output power is set precisely on the amps knob & shows on the digi meter prior to actually welding, when welding the actual value is displayed on the meter. Slope in & out gives perfect starts & finishes to every weld. Variable gas post flow control ensures coverage of shielding gas for the weld pool & electrode at the finish.
AC TIG performance
On AC TIG the arc starts instantly & is perfectly smooth & stable even at minimum amps. The output power is set precisely on the amps knob & shows on the digi meter prior to actually welding, when welding the actual value is displayed on the meter. The extended AC balance control allows you to change the AC balance through an extended range & is a really useful feature. This can be set to any position from 95% negative for maximum heat into the weld pool right through to 95% positive for maximum cleaning effect. By running a high % of negative balance the heat input into the TIG torch is substantially reduced & the heat into the job increases significantly. This allows you tackle those thicker jobs like heavy castings etc & its extends the range of the electrode so you can even run a 3.2 electrode with an air cooled torch up to 300A short term. The balance control also allows you to change the output from AC to DC – or DC+ output (reverse polarity). The variable AC frequency controls the heat spread of the arc, at low frequency’s such as 25hz the arc is soft & has a wide spread, as the frequency is increased the arc constricts to give a more focused narrow spread of heat. Again the slope controls & post flow gas control give perfect starts & finishes to every weld.
MMA ARC welding performance
On MMA welding the high OCV & built in hot start gives perfect fast arc starts on all types of electrodes. The digital meter displays precise amps values. The arc is perfectly smooth & stable on all rods from 1mm upwards & DC or AC current can be used. In addition cellulosic type electrodes 6010 etc can also be run perfectly, most machines won’t touch these. Many AC DC TIG machines won’t weld AC MMA, for some welding applications AC current is needed, our OXFORD models do it so well & you will find the arc is far superior to the old oil cooled or air cooled transformer types. In addition the AC features like balance & frequency controls allow the arc characteristics to be changed to suit each job, for instance you can increase penetration or reduce penetration by changing the AC balance, this can be a really useful feature to control where you want the most heat, you rarely get this option on other makes of machines.
All models built in compliance with with BS EN60974-1, BS EN 60974-10, RoHS, weee registered & CE marked.
All ratings above are based on TIG welding, when using on MMA duty cycles reduce by 15% & input power increases.
* minimum generator rating is for up to 75% output, for full range we suggest increase KVA rating by 40%
Standard options;Super smooth foot pedal, hand remote control, TIG torches up to 8M, TIG torches with amps control on handle, long welding cables etc. Water cooler (stand alone), Trolley for machine & gas bottle & water cooled trolley version.
Note 220E AC DC dual voltage can be supplied as 110/230V or 230/400V, please specify at time of order.
Other options (to be specified at time of order), different input voltage, pulse functions, 2A min current range, longer input cable, etc. Please ask if you want something else we can probably do it!
