AC welding current is the best because of the way the AC waveform aids in breaking down the surface oxide layer. Five testers of various genders and ages scored the torches for how easy it was to operate controls and settings with bare hands and while wearing gloves. Furthermore, this modernized automation is much more reliable than simple transformer-based welders. High Pulse Rate: The device offers a maximum pulse rate of 200Hz without causing any damage to the weld.

These alloys are insulating and have an oxide layer on their surface that melts at greater temperatures than base metals, making it difficult to join the base metal if the oxides have not been removed. We liked the large on/off button and the hands-free operation, which works from 10cm to avoid accidental triggers.

Some of these models also provide several focus options, which allows you to narrow or widen the size of the beam. H downslope: The time of welding current dropping below the set value to zero or the final current—adjustment from 0 to 25 seconds.

You can safely expect about 18 minutes of use on full beam (not especially great) and up to 17 hours on low. The StressPly Flex built-up membrane is a high strength torch-on bituminous waterproofing system, and a popular choice for refurbishment projects. Torch Flex Ultra-Vent is a high-performance torch-on base sheet, utilising adhesive strips on the underside to allow for trapped vapour to disperse throughout the roof system; preventing membrane blistering and ensuring the longevity of the system. Expect a runtime of about 15 minutes on high (150 lumens) and almost six hours on low (five lumens) and when it comes to charging time, simply unscrew the top half and it springs open to reveal a micro-USB port for the provided cable.Nevertheless, in some situations, this would probably be a better choice than the MT10, not least because its highest beam setting is easily bright and narrow enough to dazzle a fox 270m away. To get the best quality and cost-effectiveness for your welding, equipment your Flexlite torch with Kemppi consumables. A high-performance membrane that prevents water vapour from entering the waterproofing system, which can lead to the disruptive formation of condensation.
