Graphic control panel

Sigma Select simplifies advanced welding thanks to the wide selection of programs and intelligent welding technologies. You can detach the robust and ergonomic control panel and take it with you. This allows you to adjust your settings without moving away from the welding spot. The graphical display makes it intuitive to navigate functions and adjust welding parameters, with visual presentation of how your changes affect the weld.

The graphic control panel allows you to upgrade to all future functions and welding programs. Even the basic version of this control panel provides you with language variants, process and machine set-up, service menu and other smart features.

Overview

Power source

Sigma Select product news

Separate wire feeder

Some working environments will wear out welding equipment faster than others - this wire feeder is for the roughest environments. It is very resistant to impacts. It has a closed cabinet that protects the wire reel holder, the wire feed motor and the control panel from the chaos that unfolds in the production hall.

Built-in control panel for Sigma Select Compact

Some working environments will wear out welding equipment faster than others. That is why some users prefer the control panel to be build into the power source. It makes it more resistant to impacts and the chaos that unfolds in the production hall.

Two wire feeders

Get access to two different types of wire, which you can switch between easily. It is specifically useful for welders who need one type pf wire for the root pass and one for the filling layers, e.g. different materials, dimensions or solid and/or flux cored wires. Having easy access to two different wires, the welder can reduce the time spent on changing wire reels and torches.

IWF – an intermediary wire feeder

IWF is a lightweight and durable alternative for carrying around heavy wire feeders. It extends the welders’ working ranges so they are free to work far from the power source and wire feeder. It is designed for use in onshore production, offshore and onshore repair and mounting of tubes, pipes, jackets, containers and wind turbine foundations etc.

Push Pull torch

The Push Pull torch will ensure precise and stable wire feeding of the softest welding wire in the workshop - also aluminium. Aluminium is so soft that there is a high risk of the wire moving sideways out of the rollers inside the torch during welding if using a regular torch. Choose a Push Pull torch with a Graphical Smart Torch module so the welder can adjust welding settings quickly on the handle.

Benefits

IGC: Prevent over-consumption of gas and lower your costs

Save up to 50% with automatic gas control. Intelligent Gas Control prevents over-consumption of gas and gives you long term savings. With weld pools always perfectly protected, you increase the quality of each weld. Calculate your savings here.

Smart Torch Module

A Smart Torch module is placed on the torch handle, providing easy access to adjusting a variety of welding parameters. Using the graphic display, the welder can fine-tune settings perfectly, all the way down to one amp - without being right next to the welding machine.

MigaLog: Register every weld

Keep track of your welding data with MigaLog software. Analyse and document your work. Use MigaLog to extract conclusive evidence for verification in accordance with EN and ISO welding standards.

PowerArc: Secure maximum weld penetration

PowerArc allows you to build strong and solid structures in mild and stainless steel. Achieve maximum weld penetration in thick plates when welding fillet welds and butt welds with PowerArc.

Highlighted features

WPS Lock Card

Enables different levels of locking parameter settings. Ideal for compliance with Welding Procedure Specifications or prevention of incorrect settings.

Detachable control panel

Detach the control panel and take it with you. This allows you to adjust your settings without moving away from the welding spot.
