The MIG 300S + WF400 is a robust and power-efficient three phase machine. It is ideally suited to medium to heavy fabrication and requires only a 16A fuse. A full size cabinet can accept a full height gas cylinder and large diameter wheels means it can be moved from job to job with little risk of toppling. The WF400 features SWP's renowned 4-roll wire feed and allgeared drive system, minimising the risk of wire slip and so creating uniform welds. With its 5 metre interconnection and 4 metre welding torch, a work radius of 9 metres is easily achieved. The unit is also suitable for use with spool on-gun or push-pull gun, allowing for increased work radius for up to 13 metres.
