AC/DC TIG Welder 200A & Plasma Cutter 40A, Pulse, Inverter, ALU, MMA, STICK, Electrode | O251

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 10 memory locations
