Paton PSI 350 Compact Pulse MIG Welder – 400V

The PATON PSI 350 is a 400V three-phase multi-process welder. It is capable of MIG, DC, lift, TIG, and MMA processes to a very high standard. It also boasts a pulse feature on all three of these welding processes. Its 350 amp output allows for welding of up to 15MM thick mild steel, whilst its very stable “low end” current allows for welding of very thin material. The Paton PSI 350 is capable of welding mild steel, stainless steel & aluminium (when the right wire feed rollers & torch liner are fitted). It boasts a reverse polarity function, therefore it is capable of welding with flux-cored & gasless welding wires. Overall, it is a great solution for maintenance, DIY, or light production welding.

The warranty on this machine is 3 years (managed by Welding Supplies Direct in the UK).
