Newarc get new colours!

Longstanding, popular brand Newarc, who are well known for their British-made, robust, and reliable welding machines, have shed their classic orange and blue skin for a chic new grey and navy. The rebranding comes after their partnership with well-known retailer, Weldability Sif in march 2020, alongside other industry favourites such as sifWELD and Extractability. While Newarc’s fantastic quality and programming will remain unchanged and the machines will continue to be made in the UK, the new colours will bring this staple of the welder’s arsenal into the 21st century in a stylish new way. To celebrate this change, Newarc have released the first of many new collectable stickers available for FREE from their Instagram. The design immortalises the Viper - the tiny TIG machine with a bite! - in the clean new grey and navy with a subtle nod to the classic orange. Follow them on Instagram here: www.instagram.com/newarc_welding to claim your FREE sticker and stay up to date with some fantastic upcoming competitions!

1941 sifTIPS advice to women in welding: Proud to say, we've come a long way from this!

Since the beginning, sif has been a champion of women in welding, but when a brand has been running for as long as this one has, things are bound to need updating a little. While the team were deep in the sifTIPS archives this week we came across an advice column from 1941 onwards featuring Winnie the Welder offering handy tips to women new to the welding world as part of the war effort. Most of the suggestions focused on whether it was important to maintain your femininity while working and what hurdles to this end professionals could expect to face - rather than actual welding tips. Once in a while, we all need to have a good laugh at ourselves, so we’ve chosen our favourites to share with you below! Attire: As much as one dislikes seeing women in trousers, it seems to be the general opinion that for welding in factory conditions, trousered overalls of the bib and brace type are more suitable than skirts and silk stockings the trousers give protection to the legs against sparks and hot falling metal. Care of hands: Welding will not spoil your hands but to keep them soft and attractive wash them regularly and use a well-known brand of cream after the day’s work is over. Nails will not get damaged if kept well-trimmed and not too long. Care of hair: There is always a certain amount of dust in any factory, so it is advisable to wear a dark coloured bandeau or beret. A good hair rinse twice a week and regular daily brushing night and morning will keep your hair silky and fresh. The regular movement of goggles during a day’s work will spoil the most permanent of hair waves and for this reason it has been found that a head cover of the beret type affords best protection whilst still retaining that feminine charm. Care of eyes: Goggles must be worn and are generally provided. As an extra aid a daily douche with a well-known eye lotion is a good tonic, although not essential. Most girls are at first somewhat apprehensive about the daily use of welding goggles and they generally fear that their eyesight may be impaired there is no need to worry on this score providing that they are supplied with a pair of goggles fitted with Protex grade A glasses to B.S. Specification 679. These glasses are a light shade of green and are especially recommended to give 100% eye protection when used on light gauge sheet metal welding, sifBRONZE welding and aluminium welding. Grade B Protex glasses are a darker shade of green for heavy oxy-acetylene welding, but these are rarely used by girls. Don’t forget to check our social channels for a few more throwbacks as we uncover them, and we look forward to better supporting the whole welding force with some actual advice - we promise!

Weldability Sif release new sifWELD Evolution range of welding and cutting machines

We are very pleased to announce the long-awaited release of our revolutionary range of sifWELD Evolution welding and cutting machines earlier this year. We listened carefully to the feedback we’ve received in the past and have been secretly working on this range for a long time, because we wanted to get it right. The all new sifWELD Evolution range of MIG welding machines combine the very latest inverter dual pulsed technology check back for our next post on why this is important with synergic programmes designed to take the guess work out of finding the optimum welding parameters for the specific material, wire size and shielding gas, including optimum MIG welding of aluminium and options for MIG Brazing, while MIG Manual mode gives the operator full control of all available settings and most models have a supervisor lock for specific welding settings. They also feature IGBT technology, providing ideal, lightweight, multi-process machines. The sifWELD Evolution TIG range combines aerospace technology and optimised ergonomics to create a smooth and powerful TIG performance with a simple, intuitive interface. These machines provide smooth operation, with pulsing function up to 999Hz, for excellent control of your weld bead on Aluminium, steel, stainless, copper and titanium. The combination of Aerospace technology and high-end features in these machines would usually price them out of the market but you’ll be surprised by how affordable the sifWELD Evolution packages are. Finally, the range’s plasma cutters offer a smooth and reliable cutting arc controlled by a simple, easy-to-use interface, with a single point of control. The included air regulator and vapour-trap make it totally user-friendly. The display allows you to select and adjust your cutting power and view any error messages identified by the machine’s intelligent circuitry. These smart plasma cutting units detect insufficient compressed-air supply, arc failure, missing shield cup or electrode, or short-circuiting of the torch to the workpiece, and display this information clearly to the user, enabling the issue to be quickly rectified. The whole sifWELD Evolution range features large colour LCD displays on the power sources and wire feed units where applicable, with each display offering a simple, intuitive interface, where you can adjust all the settings you need.
