Portable Piping Automatic Welding Machine (FCAW/GMAW) Model: PPAWM-12Aa Performance features On-line Performance: Nil (it is designed for working completely). Application: broad (pipe welding of various structures of DN≥300 in various industries). Welding Capacity: Excellent (200 300 inch/day, which is 3 times higher than the manual welding) Operability: Good (applicable and easy to operate even if you are a new user) Surface Forming: Excellent (the welding gun will always be positioned in the optimum position) Welding compliance rate: 98% min (without re-working for the skilled operator). Driving Reliability: good (driven with friction) Price: Much cheaper than the Piping All-position Automatic Welding Machine (FCAW/GMAW). Mobility: it is light and extremely portable. Technical parameters Pipe diameter applicable: DN50 300(φ60 325) Pipe wall thickness applicable: 3 20MM Materials applicable: carbon steel, alloy steel, stainless steel and cryogenic steel,etc. Welding line applicable: various welding lines of spool pieces such as pipe-pipe, pipe-elbow, pipe-flange, flange-flange and flange-elbow, etc (a fake pipe transition connection shall be applied if necessary). Driving System: driven by three-row stainless steel and worm -worm wheel (A1/A2) or driven by two-row rubber roller and reducer (A3/A4) Clamping system: clamping with double chain manual screw Bracket system: Nil (unless the customer requires it) Counterweight System: no Counterweight Speed-regulation Mode:VF stepless speed control system Adjustment Mode: manual cross regulator Oscillating system: a product of our patented technology, oscillator driven by the common motor; nondefined oscillating width adjusting (for A1/A3)/ step motor driving oscillator (for A2/A4). Control system: a product of our patented technology, nonPLC control (for A1/A3) /PLC control (A2/A4). Welding Mode: CO2 gas shielded arc welding Welding Power: our OEM products which are famous in China (or as per customers demands)
