We subjected each torch to a heavy shower for several minutes and inspected the lamps and battery casings for water ingress.

G: Pulse duty: The ratio of the peak voltage during a pulse interval permits you to modify how deep the penetration is. A rise in pulse duty will increase penetration depth. In contrast, the reduction in depth decreases the amount of heat that enters the material, thus reducing the chance of burning more miniature sheets or elements with smaller dimensions. Haven't used it yet as it is for my daughter when she goes to festivals later in the summer, but we have tested it and it works perfectly.The light output of a torch is measured in lumens (lm); the higher the lumen rating, the brighter the light is that the torch emits. Nightsearcher’s latest offering upped the ante with a hefty 1,100 lumen light output from its 2.85Ah, rear-mounted battery, which gave a claimed 2.5 hours on full beam. Small consumables fit the small torch head, and large consumables fit the large torch head. The consumable type can be selected between the lens and standard consumables. Lens consumables have a more laminar gas flow and are used when good gas shielding is important (Ss, Al for example).

The Post Gas flow duration determines post gas flow time will be determined by the size of the tungsten and welding current being employed. If the Post Gas flow has been appropriately set, the tungsten electrode will be a clean and shiny surface. An adjustment from 0 to 15 seconds.My years as a welding inspector and supervisor have honed my ability to ensure the highest standards in welding quality and safety, making me adept at executing and overseeing complex welding operations. K AC Frequency: Adjusts the AC output frequency to regulate the arc cone’s size and enhance the directional control of the arc. The adjustment range is 40 to 200 Hz. Our current champion offers five modes – a max of 580 lumens, a mid-range 270, 30 for close work, a 10-lumen warm white for reading, and an emergency flashing white. It was certainly efficient, managing a claimed 2.5 hours at the max setting and 5.3 in the 270-lumen mode. And, if the rechargeable unit does go flat, it’ll take conventional AAA batteries. A Welding Current provides adjustment and control over the primary welding current. Adjustment range 10 -225 Amps (220V) 10-40 Amps (110V). Optional switch extension to replace the regular Flexlite TX switch. Increases trigger control accuracy when the torch is held close to the welding head.

However, disposable batteries are not only costly (especially the lithium variety), but they will end up in landfill, which is bad for the environment. The latest trend, therefore, is towards rechargeable lithium batteries that can be recharged very conveniently using a simple micro-USB or USB-C cable attached to a power source. The torch itself may be more costly but you’ll save a heap of sterling in the long run – and help save the planet too. How much should I spend on a rechargeable LED torch? If you use the mode 2T, start current, the upslope slope, and the end current isn’t applicable.If you are using the 4T mode, there are four actions. The first is to press the hands to alter the start current, the following press the button to release it to alter the current of welding, and the third-hand switch is used to adjust the end currently, and finally release the hand switch to stop welding. 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. It’s drop and water (IPX4) resistant, hefty, but not cumbersome and has been certified for use by the USA based National Tactical Officers Association. It’s expensive, but with a replaceable battery and excellent build quality, it will last for years.

The torch should be held above the workpiece using 1-1/8″ (3.2mm) space between the piece of work and the tungsten. The MH23 comes with five different beam strengths, from one lumen – just bright enough to see by without attracting attention – to a mind-bending 1,800 lumens. It also features an emergency strobe and SOS, plus a very cool locator beacon built into the torch button that gently flashes intermittently so it can be found in the darkness of a tent. AC welding current is the best because of the way the AC waveform aids in breaking down the surface oxide layer. Arc ignition with HF is the most precise and easy starting on the arc.
