Introduction Technical ARC OPTeARC ETIG S250DC – S650DC
Superior performance DC TIG machines
Now with 2020 updates # water cooler only runs when needed # slimline modern styling.
The Technical ARC OPTeARC ETIG S250DC – S650DC range are really simple to set up & use, anyone who has TIG welded previously can use these in seconds. Unlike competitors machines there is no programming needed or constant referring back to instruction manuals. In addition we have added some unique functions all aimed at improved welding performance for all materials. Our QPulse (high speed pulsing) function can increase welding productivity by up to 35% & therefore reduce your welding costs. OPTeARC technology gives you ultra smooth welding current output, this means a more stable weld pool & better looking welds! These machines will not fail in dirty or damp workshops like inverters do, they are not affected by fluctuations on input supply they will just keep welding reliably year after year. All ETIG models are complete with undercarriage for gas bottle & wheels so no expensive trolleys are needed.
The benefits of the OPTeARC ETIG machines really do add up, which makes these machines the perfect choice for all manual & automatic welding applications, including general fabrication, aerospace work, petrochemical, offshore, Oil & Gas, precision engineering, motorsport engineering, etc.
Key benefits of the OPTeARC ETIG S250DC – S650DC machines
- Superb welding performance both TIG & MMA with capability of all electrode types.
- Perfect arc starts & welds every time from min to max power on both TIG & MMA.
- Rugged reliable design unaffected by harsh operating conditions or poor input supply, guaranteed!
- Advanced features to increase welding speed, reduce heat affected zone, increase penetration etc.
- Ultra low power consumption reduces your running costs & helps the environment.
- Ready to accept our EFEED 40 cold wire feeder to increase productivity further.
Standard OPTeARC ETIG S250DC – S650DC machine functions.
- Precise current control can be set to within +/-1 amp, digital display shows preset value then exact value when welding.
- Variable up & down slope controls, 0-5 seconds upslope, 0-15 seconds downslope range.
- Pulse function allows normal pulse function 0.5HZ – 200Hz or QPulse (high frequency pulsing up to 2KHZ or 2000PPS)
- Preset exact peak & base current prior to welding.
- Torch trigger latching 4T/2T, (when used on 4T with our OPTeARC ETIG wire feeder the trigger can control wire start/stop)
- Variable gas preflow & gas post flow control, 0-5 seconds preflow, 0-15 seconds postflow range.
- Electronic pulse HF for precise instant arc starts (I.T. friendly so will not affect your phone or PC etc)
- MMA electrode welding with super smooth arc on all electrodes & will also weld cellulosics!
- Remote current function allows use of a foot pedal or hand remote or special current control on TIG torch.
- Automatic compensation for varying input power, long extension leads or unstable generators.
- Water cooled versions now only run the cooling when needed-reduces noise & energy consumption.
- Water cooled versions include torch & pump flow protection.
Further info.
The ETIG S models offer superior performance and reliability for industrial welding applications compared to US and EU-made inverters. These models outperform inverters without suffering from their reliability issues and high repair costs. ETIG models are easy to maintain and troubleshoot, featuring a single low-cost control PCB with diagnostic LEDs for remote fault diagnosis.
Reliability and simplicity are prioritized, including protection against real-world conditions such as overvoltage spikes, short circuits, dust, and dampness. Although not as compact as inverters, ETIG S models provide portability similar to trolley-mounted inverters. The inclusion of water cooling, with an option to disable it for air-cooled torches, enhances performance and extends pump lifespan.
All ETIG S models are compatible with the EFEED 40 automatic cold wire TIG feeder, boosting productivity by at least 30%. This feeder synchronizes with the ETIG, ensuring precise wire delivery for optimal welding, especially during pulse operations. The 4T operation on the ETIG provides complete control over each weld, offering operators flexibility and efficiency.
Standard supply & options & accessories
Standard supply for all models;400V 3phase input, 3M mains input lead, 3M work lead, blue panels, wheels & caster undercarriage with gas bottle carrier.
Options include; 230V or 480V or other input voltage, water cooling built in (with flow protection), calibration for EN1090 etc, robotic interface, longer cables fitted, extra functions added, additional hot wire TIG output.
Accessories include;TIG torches air cooled & water cooled 4M or 8M, Electrode lead & holder, remote control units, foot pedal with stop/start & variable amps, EFEED40 cold or hot wire feeder. Water cooling kit to fit into air cooled models.
