OPTeARC EWELD MST - further reading

OPTeARC EWELD power sources are British made industrial machines built using our unique Mitsubishi hybrid chopper technology. This design gives you all the performance benefits of a good inverter based machine with instant arc starts, a smooth superior arc & very low power consumption, but with the rugged reliable build of a transformer machine & dual voltage input for easy connection to any supply.

Due to the high efficiency of our OPTeARC technology the size, weight & input power are reduced by a massive amount compared with conventional machines. Furthermore these tolerate harsh operating conditions such as extreme temperatures, damp & dust & can be used outside in the rain. Internal construction is simple with minimal parts & only one control PCB, these machines will not fail in dirty or damp workshops like inverters do, they are not affected by fluctuations on input supply they keep welding reliably year after year. They are equally happy in any environment including industrial workshops, off shore, oil & gas, mobile welding, outside on construction sites etc. All models are generator friendly & will run from up to 100M extension cables. Dual voltage offer even more flexibility for site welding. Real go anywhere weld anything machines packed full of power!

MMA stick welding – CC Super smooth welding performance on all electrode types. High OCV with hot start guarantees fast arc up even on dirty & rusty material. These weld all electrode types including cellulosic 6010 etc which most machines will not touch. A remote current control can be used to adjust the amperage up to 100m away with additional stop start of output if required.

MIG/MAG welding CV Plug in a wire feed unit & you have a superb performance MIG machine. The arc is superior to conventional MIG machines with a smooth consistent arc & minimal spatter. The variable inductance control means you can tune the welding arc to give the very best welding characteristics for the job. These machines also weld gasless self shielding wire perfectly. Weld from the thinnest car panel at 20A right up to RSJ work, digger buckets, wear plates etc. Steel stainless steel & aluminium etc, also takes our spool gun for even better weld aluminium welding.

TIG welding CC, Plug in a TIG torch & you have a DC TIG welder. Weld from 10A to max current with a smooth stable arc. Lift arc technology means no HF interference so safe for use on vehicles etc. The TIG torch can be a simple gas valve type for basic lift TIG, or our switched type which starts & stops the arc from the micro switch, Ideal for stainless steel, mild steel etc, also the torch polarity can also be reversed to weld thin aluminium up to 3mm.

EWELD MST functions & features

EWELD MST Technical specs 220A, 250A & 300A

Approx case size all models           260mm W x 520mm L x 420mm H (excludes exterior hardware)

*Duty cycles & inputs are quoted at 40ºC; on TIG welding, at lower temperatures the duty cycle will be higher, for MMA or MIG duty cycle reduces a little & input increases a little.

Standard supply, options & accessories

Standard supply for all models;  230/400V dual volt, 3M mains input lead, 3M work lead, blue panels.

Options include; different input voltage, validation for EN1090, TIG gas solenoid built into MST, HF TIG functions.

Accessories include; Electrode lead & holder, MIG wire feeder for MST, MIG torches, TIG torch options, remote control units, foot pedal with stop/start & variable amps,
