New MIG / MAG hand welding torches
MIG / MAG hand welding torch .
MECHAFIN ’ s Push-Pull unit is an intermediate drive unit to which the conventional welding torch can be connected .
The new MEX torch series from Swiss manufacturer , MECHAFIN AG , has been designed to withstand tough conditions in shipyards ; oil platforms ; coal mines and in the automotive or railway sectors .
“ It provides the operator with maximum comfort for a fatigue-free welding process . The adapted ergonomics and placement of the probe , as well as its design in combination with the twocomponent handle and the ball joint , ensure comfort in every working position . [ This means high-quality welds ] and increased work safety ,” said the Swiss welding specialist .
“ Thanks to the quick-release fastener on the handles , the torches are extremely easy to service . A torch neck can be replaced with ease , should
this be necessary . This saves time and reduces service costs . The torches feature long service life of wear parts . Optionally , LED lights or push buttons are available for controlling the welding system , which further increases welding comfort ,” it continued .
MEX welding torches also offer “ optimised button position for fatigue-free , safe operation ”, as well as high mechanical load capacity . Designed for easy maintenance and serviceability , they also feature a separate shielding gas hose for improved weld pool coverage .
MECHAFIN AG also provides wear parts such as gas nozzles , contact tips and liners for all its MIG / MAG welding torches to cover a range of requirements . n

Magnetic lifting system
Alfra GmbH presented its TML 250 magnetic lifting system at the Schweissen and Schneiden trade show in Essen , Germany , this September .
“ It has been designed for strong performance on thin-walled materials . Its dead weight is just 3.5kg so it is up to 70 per cent lighter than magnets with similar performance . Maximum load capacity is 250kg ( with 3:1 safety factor ) and tear-off force is > 750kg from 10mm steel ( S 235 ). It offers 360 degrees rotatable load swivel
and one-handed activation is possible ( even between the flanges of a T-beam ),” the manufacturer explained .
Alfra manufactures and distributes electrical devices and tools for punching and drilling that are suitable for use on materials with thicknesses ranging from 0.8mm to 100mm . It also offers a wide range of applications in patented magnetics and lifting technology .
The German manufacturer has two factory locations at Hockenheim and Berlin-Stahnsdorf . n

Tight connections
Nedschroef makes it possible to connect sheetmetal without pre-drilling by using flow-drilling metFlow ® screws and precision robots ( without compromising on strength ). This process can be applied to highstrength sheet materials that are difficult to connect in multiple layers . This approach is also suitable for the pre-assembly of components .
“ Various materials can be connected , such as steel and aluminium . Connections with CFRP are also possible . The connection with its metric thread is tight and durable and can withstand great stress , although it can be disassembled if necessary . Components do not require a pre-drilled hole or tapped mating thread , and tolerances can be easily compensated for ( which saves cost ),” it explained .
The Koninklijke Nedschroef Holding B . V . based in Helmond , the Netherlands , has developed connection technology worldwide for 125 years . Intelligent engineering , fasteners and individual forming technology solutions from Nedschroef are used in a range of industry sectors . Nedschroef employs 2,200 people in 11 countries and achieved sales of around 644 million euros in 2022 .
Since 2014 , Nedschroef has been part of the Chinese Shanghai Prime Machinery Company Ltd ( PMC Group ). n
