Overview
The RAZOR200AC/DC is a Digital Controlled square wave AC/DC TIG inverter welder with full TIG functionality that offers
simple step by step digital setting of functions and parameters providing you with 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 controlling the start and finish of the weld process at a professional level. Digital Pulse Frequency Control gives
full parameter setting of Peak Current, Base Current, Pulse Frequency and Pulse Width, allowing control of heat input into the work for
penetration control and minimising distortion. AC Square Wave with Balance Control gives maximum control of the electron flow at the
tungsten allowing to set the AC TIG arc for maximised cleaning of the oxide layer on aluminium to adjustment for a deeper penetrating
weld. Combined functions of the RAZOR200AC/DC ensures comprehensive control of welding parameters when welding AC and DC
weldable materials to produce high quality TIG welds. Our unique Torch Remote Control Interface provides remote amperage control
from the torch in both static and live welding modes. The DC MMA welding function delivers a smooth and stable arc allowing easy
welding with electrodes obtaining high quality welds including cast Iron, stainless and low hydrogen. The added bonus of Arc Ignition
and Arc Force control allows you to set the ideal arc condition no matter what electrode you choose. The RAZOR200AC/DC has raised
the benchmark for 240V single phase AC/DC welders making it ideal for multiple applications; aluminium & stainless steel fabrication

MMA (Manual Metal Arc) Welding
Oneofthemostcommontypesofarcweldingismanualmetalarcwelding(MMA)orstickwelding.Anelectriccur-
rentisusedtostrikeanarcbetweenthebasematerialandaconsumableelectroderodor‘stick’.Theelectroderod
ismadeofamaterialthatiscompatiblewiththebasematerialbeingweldedandiscoveredwithauxthatgivesoff
gaseousvapoursthatserveasashieldinggasandprovidingalayerofslag,bothofwhichprotecttheweldareafrom
atmosphericcontamination.Theelectrodecoreitselfactsasllermaterialtheresiduefromtheuxthatformsaslag
coveringovertheweldmetalmustbechippedawayafterwelding.

•Thearcisinitiatedbymomentarilytouchingtheelectrodetothebasemetal.
•Theheatofthearcmeltsthesurfaceofthebasemetaltoformamoltenpool
 attheendoftheelectrode.
•Themeltedelectrodemetalistransferredacrossthearcintothemoltenpool

Manualmetalarc(stick)electrodeshaveasolidmetalwirecoreandaux
coating.Theseelectrodesareidentiedbythewirediameterandby
aseriesoflettersandnumbers.Thelettersandnumbersidentifythemetal
alloyandtheintendeduseoftheelectrode.
The Metal Wire Coreworksasconductorofthecurrentthatmaintainsthearc.
Thecorewiremeltsandisdepositedintotheweldingpool.
The covering on a shielded metal arc welding electrode is called Flux.
Theuxontheelectrodeperformsmanydifferentfunctions.
These include:
● producing a protective gas around the weld area
● providinguxingelementsanddeoxidizers
●creating a protective slag coating over the weld as it cools
●establishing arc characteristics
●addingalloyingelements.
Coveredelectrodesservemanypurposesinadditiontoaddingllermetalto
themoltenpool.Theseadditionalfunctionsareprovidedmainlybythecover-
ingontheelectrode.
