SifWeld MTS 400 Air Cooled Inverter Welder

The SifWeld MTS 400 is an electronically controlled MIG/MAG/MMA industrial welding package featuring IGBT inverter technology. With clear digital displays, low-spatter, polarity reversal (for FCAW) and 5m standard interconnecting cables, along with an external 4-roll wire feed system which accommodates up to 15kg D300 wire spools.

Target Applications
The SifWeld MTS 400 is designed for use in heavy-duty fabrication applications such as structural steel and marine/shipyard tasks. This unit can be used to weld mild steel, low-alloy, stainless and aluminium in solid and flux-cored MIG applications. It can also be used for DC MMA welding (DC+/DC-) and scratch-start TIG welding.

Further Information
The SifWeld MTS 400 control system allows infinitely-variable control of welding voltage, wire feed speed, crater current and burnback. The power source also benefits from a 4T/2T torch-latching feature and gas-line purging. It offers a high duty-cycle for applications requiring long runs, and features adjustable burn-back control.The separate, removable 4 roll wire feed unit offers four gear driven rollers and a counter-balanced wire tension system for precision wire feeding. The wire feed unit houses the wire feed speed and voltage controls and wire-inching feature, to provide you with complete control of your feed rate when used remotely via the interconnecting cables - at up to 10m (optional extra). The ergonomic design of the SifWeld MTS 400 incorporates an integrated torch holder for easy storage of your torch whilst not in use. The wire spool cover protects your wire from the elements. A robust trolley accommodates a full size gas cylinder and includes a wire feed unit mounting bracket, which is ideal for applications. The mounting bracket allows the feed unit to rotate a full 360C°, whilst ensuring your interconnecting cable is secured via the attachment bracket, and keeping cables securely in place. It also incorporates a storage compartment for common spare parts to be stored.
