Introduction Technical ARC OPTeARC ETIG C220-C500 DC

Superior performance DC TIG machines – 220A-500A

From Nov 2019 – now with pulse built in standard & bigger range available.

The ETIG compact 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. 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.
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 Technical ARC OPTeARC ETIG C220-C500 DC Compact machines.

• Superb welding performance on 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!
• Ultra low power consumption reduces your running costs & helps the environment.

Standard Technical ARC OPTeARC ETIG C220-C500 DC Compact 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.
• Torch trigger latching 4T/2T.
• Variable gas post flow control, 0-15 seconds postflow range.
• Built in pulse function to control heat input.
• 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.
