OPTeARC EWELD MST- further reading

OPTeARC EWELD MST 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.

MMA stick welding / arc air gouging- 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. A remote current control can be used to adjust the amperage up to 100m away with additional stop start of output if required. All models are also suitable for arc air gouging, see notes below on electrode sizes.

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. 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 thin sheet right up to the heaviest applications. Steel, stainless steel & aluminium etc.

TIG welding – CC, Plug in a TIG torch & you have a DC TIG welder. Weld from 20A 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

*For arc air gouging (CAC) the maximum recomended size of electrode is 6mm for 400A, 8mm for 500A & 10mm for 650A

EWELD Technical specs 400A, 500A & 650A

Approx case size all models           310mm W x 650mm L x 530mm H (excludes exterior hardware)

*Duty cycles & inputs are quoted at 40ºC; on TIG welding, at lower temperatures duty 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;  400V 3phase input, 3M mains input lead, 3M work lead, blue panels.

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

Exterior hardware options, lifting eyes, under carriage (wheels & casters), pull handle.

Accessories include; Electrode lead & holder, MIG wire feeder suitcase type 24V, MIG wire feeder suitcase type inline (across the arc), MIG torches, TIG torch options, remote control units, foot pedal with stop/start & variable amps,
