Descript of VECTOR Digital Welding machine AC/DC TIG O251 Plus Inverter ALU TIG CUT ARC MMA STICK Electrode

A total solution of precise AC/DC TIG PLUS welding and plasma cutting machine.

O251 built base on the Mastertig System offers precise, expert AC/DC TIG welding process. It’s a precise aluminum welding specialist that suits all welded materials. Modular design allows you to build the package that best suits your needs.

O251 also comes with a 50A@60 heavy duty cycle plasma cutting power source. What you need for any metal welding or cutting works, you just get this combo machine and it’s all you needs.For TIG and Stick Welding.Easy operation and full functions: From the control panel allowing fast adjustment of all necessary controls for DC, AC TIG welding with either HF or contact ignition. It’s also very convenient to store or call out the welding parameters from the memory channels.

Important functions & device information at a glance

Precision Arc Performance:

♦ DC+/DC-: Improved TIG starting. Now starts DC(-) to maintain a sharp tungsten.

♦ Lift-Arc start provides AC or DC arc starting without the use of high frequency.

♦ Adjustable AC output frequency allows the operator to focus the arc minimizing the heat affected zone.

♦ Extended AC Balance Control helps maintain a pointed tungsten to direct the arc in the weld joint.

♦ Independent amplitude/amperage control allows EP and EN amperages to be set independently to precisely control heat input to the work and electrode.

♦ Multiple Waveshapes:

♦ Standard Squarewave for fast travel speeds and excellent puddle control,Sine wave for a traditional softer sounding arc,Triangular wave to reduce the heat input into the weld at low amperage.Soft squarewave for a soft buttery arc with maximum puddle control and good wetting action.

♦ Pilot Arc for superior arc performance and easy start.

♦ HF or Non-HF Arc ignition: reliable plasma arc initiation without high frequency.

♦ Continuous Output Control: focus the arc for different material thickness.

♦ Rapid Arc Restrike: fast cutting through gaps, even expanded metal.

♦ Powerful with heavy duty: 200A @50%.

♦ 10 channels memory capacity
