The TecArc OPTeARC C250 is a conventional, transformer based DC TIG welder, suitable for the welding of mild and stainless steels etc, giving excellent weld characteristics.  Very simple to use and full of features such as slope up and down, trigger latching etc, necessary to make expert quality TIG welds.  The ETIG range are constructed using a conventional transformer but with the added benefit of hybrid chopper technology.  The results are excellent arc starts as well as a smooth and stable arc, with low power consumption as well as rugged reliability.

Technical Arc believe this technology lasts longer, provides great reliability and is more serviceable than their inverter counterparts.  The C220 and C250 in the OPTeARC ETIG range are dual voltage too, being able to run the machine on 3 phase or single phase, depending on where the machine is being used and what power supplies are available.  Designed to withstand the harshest of environments, they are equally happy in any environment including industrial workshops, off shore oil & gas, mobile welding, outside on construction sites etc.
