Lincoln Invertec 150S & 170S


Lincoln Invertec 150S & 170S Arc Welders

The Invertec, 150S and 170S from Lincoln Electric offers a range of machines built with the job in mind. These stick machines are suited to a variety of applications and working environments, ensuring that there will be a machine to meet your needs.

Across the range, these designs have focused on providing excellent welding and starting behaviour in a robust and reliable package. From this foundation, each unit is further equipped with a unique set of features and capabilities to guarantee there is a machine perfect for your application.

Welding machines need to be tough. At Lincoln Electric we know that modern equipment needs to be capable of handling harsh environmental conditions. That is why we have built this range in a robust metal case with large rubber corners and push control buttons for added protection. Rugged and robust on one hand, portable on another; the Invertec 150S and 170S are lightweight and easy to handle in any situation.
Amps are not the only requirement! A good start and smooth arc requires more than simply amps and voltage. The Invertec 150S and 170S are equipped with POWER SURPLUS in addition to normal welding current. This advanced control monitors
the arc, constantly adjusting output to ensure a stable arc and first-rate starting, even when the arc-length varies greatly.

The superior arc control achieved with POWER SURPLUS makes the difference between a Lincoln Electric excellent welding performance than any other ordinary welding machine on the market. Anti-Stick included as standard! When an electrode is started by striking, the tip of the electrode may “stick” on the work peice at the full set current. The ANTISTICK feature detects when electrode sticking occurs and automatically switches the current down to minimum to
prevent the electrode from remaining attached to the work piece and overheating.
