 The most important user functions of PRO-MAG control are: - The standard 2-cycle and 4-cycle function for short basting or long welds. Fatigue-proof working is thus ensured for any welding tasks.
- With the integrated position and interval control, optically perfect point and slot welding or uniform, reproducible basting welds are no longer a challenge.
- An integrated creeping and striking automatic ensures a rapid and safe strike of the arcing.
- The feed automatic automatically adapts the wire speed over a large range with the step switch when the power decreases or increase so that it is not necessary to continuously regulate.
- The permanent control of the supply voltage with compensation of fluctuation ensures a smooth and steady arcing with optimum welding
results. - When the welding process is finished, the free arcing automatic ensures a constant wire length end, which safely prevents the wire from sticking to the workpiece or to the current nozzle.
(may be adjusted individually) - The threading automatic increases the feed speed when the wire is treaded automatically.
- The safety cutoff prevents from unintentional striking and unwinding of the welding wire during the K-cycle operation, as well as from the risk of fire which may result thereof.
- Individually adjustable after gas flow time which automatically adapts the after gas flow at the individual regulating steps. Thus the melting bath is protected after finishing the welding process until it is solidified.

Powerful 4-coil wire feed (from PRO-MAG 250-4) - The electronically controlled 2- or 4-coil wire
drive ensures a steady and precise wire feeding also for the tube packs with a length of 5m. The pressure may easily be adjusted by a single setting screw and ensures a uniform pressure on all driving rollers. These rollers are toothed to one another and, this way, they always have the same number of revolutions.

The power parts - All high performance transformer
and smoothing chokes are exclusively assembles with high-quality, double- isolated enamelked copper wire. The dependable operational reliability is also reached by coiling of layers with isolation between the layer and the additional vakuum impregantion. Thus all regulations of the insulation class H are fulfilled.

The self-regulating process control - The electronic control designed in contactless
semi-conductor technique is absolutely maintenance- free and reliable. By an integrated switching circuit, all user functions are executed and checked by permanent control. These malfunctions are excluded.

High-dynamic throttle system (HD-throttle) - The HD throttle system ensures
an extremely smooth and highly dynamic arcing. Optimum welding results with rare sputters when welding steel, special steel and aluminum make of the PRO MAG devices the “allrounder” with best welding properties.
