AC can be used specifically for TIG welding aluminium and aluminium alloys. The balance between positive and negative can be adjusted to control the amount of oxide cleaning or a more penetrating weld. When welding in AC current HF pulse start allows easy arc starting when welding aluminium.
DC TIG can be used for all steel, stainless steel, copper and alloys, titanium. When welding in DC current HF Pulse start allows easy not contact starts for critical applications.
HF Pulse Start
HF Pulse is a non-contact arc starting method allowing easy arc start without the interference problems with conventional HF and eliminates tungsten contamination. Available in AC or DC TIG mode.
Hot Start for Manual Arc
Built-in “Hot Start” feature in stick mode for even better arc starting.
Built in “Arc Force”, constantly monitors arc voltage and will boost output if low arc voltage occurs.
Lift Arc TIG Start
Easy to use lift arc starting for TIG welding. Eliminates scratch starting and tungsten electrode damage.
The Weldarc 200i is tolerant to unconditioned power from generators. It has been optimised and tested for compatibility with appropriate portable generators.
*Generators used to power this equipment must have a minimum capacity of 10kW continuous.
Due to variation between generators by different manufacturers, it is impossible for WIA to validate operation from all generators. Therefore, WIA recommend that operation of equipment on the generator is confirmed before purchasing either welder or the generator.
