The unit is powered by a rechargeable 400Wh lithium-ion battery which, when fully charged, delivers sufficient power to weld up to eight 3.25mm-diameter electrodes or 18 electrodes of 2.5mm diameter.

"AccuPocket weighs just 11kg, giving users unprecedented freedom of movement in manual electrode and TIG welding," Smenco says. "This makes AccuPocket the ideal solution for repair welding or site-erection work in remote terrain where there is no direct access to mains electricity."

The company says the unit exceeds Australia’s stringent safety standards by having an open circuit voltage (OCD) of 12V, which is three times lower than the 35V maximum required.

"When the welding circuit resistance is greater than 200 ohms (that is, when touching the human body) the OCV is limited to 12V and the VRD must be active within 0.3 seconds after welding stops," Smenco adds.

"Thanks to its facility for battery-powered operation, AccuPocket minimises time-consuming weld preparation work. This means that in many applications, it is actually more economical, over its service life as a whole, than conventional electrode welding systems."
