Each Heliarc machine comes with leading-edge features built to give TIG welders the edge they need to work efficiently and make the most of their skills.
Immediate control of heat input
Controlling the heat in your arc is easy with either the optional FC-5C foot control or TIG torch-mounted remote current control. Additionally, these machines feature a manual pulsing heat control function to optimize operator control during welding. Simply pressing the torch switch quickly reduces the current to a pre-set base and pressing it again returns it to the set current.
Pulsing allows for lower heat dissipation, better control of the weld pool, less plate deformation, and more even welds. Both AC and DC pulsing is used to regulate heat input and control the pool, making it perfect for welding thin materials. DC pulsing, with square wave, cuts current peaks and provides symmetric power, a stable arc, and perfect interfusion between base and filler material. The duty setting allows for an easy adjustment between pulse and background time.
Controlling arc cleaning and penetration is easy with the AC balance setting, as is regulating the heat on the electrode.
Allows control of arc width and penetration, making both wider arcs with less penetration or narrow arcs with deep penetration and faster speeds achievable.
