Welding package for heavy duty applications

With clear digital displays, low-spatter, polarity reversal (for FCAW) and integral 4-roll wire feed system able to accommodate up to 15kg of wire spools, the unit is designed for use in heavy-duty fabrication applications such as structural steel and marine/shipyard tasks.

The SifWeld MTS 400 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.

Its control system allows infinitely variable control of welding voltage, wire feed speed, crater current and burnback. The power source also benefits from 4T/2T torch-latching and gas line purging. It offers a high duty-cycle for applications requiring long runs, and features adjustable burnback 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 as well as the wire-inching feature, to provide complete control of feed rate when used remotely via the interconnecting cables, up to 10m (optional extra).

The unit's ergonomic design incorporates an integrated MIG torch holder for easy storage when not in use and a wire spool cover to protect the wire from the elements.
