PRESTOTIG AC/DC - отговарящи на изискванията на специалистите в ТИГ заваряването машини
PRESTOTIG AC/DC 240(W), 310(W)
PRESTOTIG AC/DC machines are designed to meet the expectations of the most demanding welders. Optimum performance is associated with the ruggedness necessary for daily work both in the workshop and on site. Improving your quality and productivity is our target. PRESTOTIG AC/DC machines are the most advanced equipment available on the market for the applications.
The technical characteristics that make the difference.
• PRESTOTIG AC/DC are designed for manual TIG welding of all metals,
including aluminium and stainless steel.
They can also be easily used for MMA welding.
• You can choose single- or 3-phase primary alimentation in 2 intensity range
- PRESTOTIG 240 AC/DC is a 230 A @ 40% in a single phase power source,
for joining aluminium up to 5 mm thick,
- PRESTOTIG AC/DC is a 300 A @ 40% in a three phase power source.
• All the characteristics that TIG welding need. PRESTOTIG AC/DC permits TIG
welding with any type of current: AC, DC+, and DC-.
Additional features for improved results:
• TACK FOR THIN device
Is a dedicated process for welding thin sheet. Developed with a strict focus on assembly and welding thin sheet.
• Pulsed TIG and “synergic” pulsed TIG
The pulsed TIG process, due to the possibility of regulation of all parameters, allows improved control of the weld pool. In order to simplify the regulation, there is an additional process, synergic pulsed TIG. With the synergic pulsed system, there is no need to adjust the welding current or other pulse parameters that are pre-programmed. The pulse frequency gives a highly concentrated arc and increases welding speed.
• COMPOTIG
Sturdy and robust process that uses simultaneously AC and DC. The composition of the two different processes can be regulated to obtain complete penetration and effective cleaning. More AC for better cleaning and more DC for better penetration.
• The “LEVEL” function
With the “4 levels” function, two current levels can be chosen, the welding current and the base current. This facilitates the change from one to the other by rapidly pressing the torch trigger. The “LEVEL” function can be used to adjust heat input momentarily, to change welding positions or to replenish the filler metal supply without having to stop welding.
