The RAZOR200ACDC is a Digital Controlled Square Wave AC/DC TIG inverter welder. Intelligent digital control of the main functions are
realised by software providing ease of operation and high accuracy, software upgrade is possible by simple download function. Full TIG
functionality, offering simple step by step digital control of functions and parameters providing complete professional control. HF arc
ignition provides pre-gas with instant arc ignition leaving no tungsten inclusion or contamination of the tungsten electrode. Digital set
of Pre Gas Time, Start Current, Up Slope and Down Slope Time, Finish Current Level and Post Gas Time with the choice of 2T or 4T
trigger function allows control of the welding process at a professional level from start to finish. Digital Pulse Control gives full parameter
setting of Peak & Base Current, Pulse Frequency & Pulse Width providing control of heat input, penetration & distortion. AC Square
Wave Balance gives control of the electron flow at the tungsten, the AC Tig arc can be adjusted from maximum oxide-layer cleaning on
aluminium through to a deeper penetrating weld. Remote Control Interface provides optional remote amperage control at the torch or
foot-pedal control. DC MMA welding delivers a smooth and stable arc for easy welding of electrodes producing high quality welds
including cast Iron, stainless and low hydrogen. Arc Ignition and Arc Force control allows you to set the ideal arc condition no matter
what electrode you choose. Optimised auto protection of the power input provides auto shut down of the machine when large scale
fluctuations occur. Unique air channel design increases the heat dissipation of the power device, control circuits, minimises dust
absorption, thereby greatly improving longevity and reliability. RAZOR200ACDC is the new standard for 240V AC/DC welders making it
the ideal choice for experienced or novice welders of Aluminium, Stainless and Steel materials. Built to our specification and
manufactured in compliance to AS/NZ60974.1
