Model Number

ZX7-315

I. Features
��Automatic protection from overcurrent, overheat, over/under voltage
��Arc burns stably, quiet molten pool, fine welding seam
��Touchable arc ignition in TIG welding
��Support digital display of current and voltage, and presetting of current
��Small size, light weight
��With arc-ignition current adjustment switch, can easily adjust the arc-ignition current and optimize the arc-ignition effect. With pushing current adjustment switch, can strengthen the arc force and prevent the welding electrode stuck to workpieces
��Can be used together with all kinds of welding electrode with a diameter smaller than åÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂœ­5.8mm, used in almost all areas
��Can be equipped with distance-control box according to the requirements of customers, simplify the operation
