WELDER + PLASMA CUTTER O251
The O251 from Vector Welding is a professional combination unit for welding and plasma cutting.
With its adjustable AC/DC (alternating current / direct current) mode, it can be used for all weldable metals, including aluminum.
With 10-200A in TIG mode, 10-200A in MMA/electrode mode and plasma cutting with 10-40A the machine is well suited for installation, repair, maintenance and DIY.
O251 FEATURES & ADVANTAGES:
- 3 in1 combi device: AC/DC TIG, MMA/STICK, Plasma cutting
- AC/DC TIG welding: Processing of all weldable metals, including aluminum
- The adjustable AC output frequency allows the operator to focus the arc, minimizing the heat affected zone.
- Advanced AC balance control helps maintain a sharp tungsten needle to precisely control the arc in the weld joint.
- Pulse function: during pulse welding, the welding current alternates between output and peak current at the desired frequency. The longer the intervals, the less energy and heat is supplied to the workpiece
- HF Ignition (TIG)
- Lift-Arc-Start: Allows AC or DC arcs to be started without high frequency.
- 2 T/4 T
- MMA/STICK/E-HAND: coated electrodes are used - in this process the electrodes are arc carrier and filler metal in one.
- Hot Start: each time the welding machine is restarted, overcurrent is provided to support the ignition of the arc.
- Arc-Force: melted material is transferred more easily to the workpiece. Prevents the arc from extinguishing if this material causes contact between the electrode and molten pool.
- Anti-Stick: automatically switches off the welding generator if the electrode sticks to the workpiece and must be removed by hand without damaging the electrode clamp.
- Plasma cutter: CUT function using a plasma beam generated by electricity. This melts the material and removes it with compressed air - a precise cut is produced. With this method all conductive metals can be cut (e.g. steel, stainless steel, aluminium, copper, etc.)
- Cutting thickness: maximum 16mm (hand-guided), quality cut 10mm (hand-guided) modern IGBT (Insulated Gate Bipolar Transistor) allows fast and therefore low-loss switching of electrical currents
- Modern IGBT (Insulated Gate Bipolar Transistor) enables fast and therefore low-loss switching of electrical currents
- Job memory: the O251 has 9 memory locations
