Still a bit hit and miss, but cheap. And with a professional look. Great. True, they do brake the unit on a sloping workshop floor. But then there is the braked swivel
caster you see her e. You will find it under every single M. Expensive, but worth it. Guaranteed to stay solid as a rock in your trailer at the back. If you don’t want your precious unit to fly off you had better tie it down.
Example 4
The easiest way to fool the average craftsman is by palming him off with a cheap control system. Why? Because it costs a fraction and looks just the same. But after just a short time these cheap imitations will show signs of wear and tear. Your wire feed is thrown off balance, resulting in a shift in the free burning time. The result: nozzle burnout. The “best bit”: At first you assume that you are at fault. You never really realise what is going on. Even when the whole control system packs up within four years at the outside. 80% of all systems offered in the marketplace today fall under this category. Every M comes with a microcontroller. No wear. Precise, digital con- trol of every single function. Our industrial systems all work to this high engineering standard. The best currently available. So you see - there are welding systems and welding systems. The choice is yours.
Why is it exactly that the world and its wife would rather be driving a Mercedes than an Opel? Looks better? More status?
Is that all? Just ask a taxi driver. A cabby will make a professional judgement based on hard business sense. After all, he drives it. Or why is it that a hammer drill will slice through the concrete in just 3 seconds where others plug away for 15 seconds to make the same sized hole? Nobody who drills for a liv- ing would put themselves through that. It is no different if you look at our M system. If you are a professional you have no choice but to opt for this degree of MIG-MAG perfection. An amateur who does the odd bit of welding can save a good 400 Euros by shopping around for some sort of welding system. We don’t supply this particular market and we never will.
An M from Lorch offers inner values - values we set out to achieve at an enormous cost in terms of time and effort.
Example 1
90 % of all welding systems fall short of the specified output level once they have com- pleted the warm-up phase. If the rating plate says 350 amperes, chances are that will only apply to a cold start. After just 5 minutes, the output takes a nose dive - but stealthily. In other words while you are welding.
This type of behaviour can drive a profes- sional welder round the bend. An M will go on giving just what we promise it will after hours. And years.
Example 2
It is generally true that the sum of all details is what sets an object apart from the rest. Take a look at just one such detail - the knob next to the wire insertion. This is something you will be lucky to find on any other unit. But actually it is an ingenious detail. It allows you to insert the wire without picking up the torch. This unassuming looking knob is used to switch the wire feed then and there. Without it, the whole process becomes an imprecise science as your eyes move back- wards and forwards between the torch switch and the wire feed roll. This knob with its sur- round costs us around 12 Euros. Others don’t bother with it, although they are perfectly aware of its benefits. Savings like this allow them to shave more off the
purchase price. Good for them.
Example 3
Underneath every weld- ing system are casters. Available to manufacturers
in different qualities ranging in price from 10 Euros for a set of four up to 98 Euros. The question every producer asks is: How much do I invest in the bit you don’t see? Most decide this is a place they can afford to cut corners. Of course they roll. But efficient braking is quite a different matter. And they struggle over obstacles and around corners. At Auenwald, these are the sort we mount under our waste paper bins. We don’t see any other valuable purpose for them. The other group among our competitors opt for casters with a k ick-stop brake.
45 “The 2nd M series has taken on a cult status.
The basis of every M. From the 2020 to the 2095.
6 output models from 140 to 350 ampere. With up to 24 settings. Also with 4-roll drive. Lid opening to the side for improved access. Fully insulated inner floor to protect the welding wire basket against phase to ground short circuits. Absolute feed precision - more accurate pressure setting, no wire deformation, precise wire alignment and wire trans- port. Special wire inlet guides made of moulded brass to ensure easier running for steel and stainless steel as well as alu-
minium. Sophisticated electronics, compact central torch connection, adjustable wire roll brake, even easier operation and new, ergonomic outside front. A transformer-inductor combination which is of course copper-wound and ideally matched. A sturdy diode rectifier with overvoltage protection. Switching stages for optimum working points in every posi-
tion. MIG-MAG logic, which controls the electronic welding current, feed, wire burn-back, gas postflow and spot welding time. Fully adjustable spot welding time. Air cooling for a higher duty cycle. Thermocontrol as overload protection. Horizontal wire spool take-up, suitable for large and small spools with no extra adaptor. Removable ground cable with quick-action coupler. Galvanised sheet steel housing with powder-coated front and sides. Integrated gas cylinder holder
and compliance with the standards EN 60974-1 a, CE and S marks.
