    SAFETY Welding and cutting equipment can be dangerous to both the operator and people in or near the surrounding working area if the equipment is not correctly operated. Equipment must only be used under the strict and comprehensive observance of all relevant safety regulations. Read and understand this instruction manual carefully before the installation and operation of this equipment.
  • Page 5 SAFETY Fire hazard. Welding/cutting on closed containers, such as tanks, drums, or pipes, can cause them to explode. Flying sparks from the welding/cutting arc, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of the electrode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding/cutting.

It means that the amount of time that it takes the AC square wave to complete a full cycle switch from positive (+) to negative (-) CONTROL can be adjusted from 20Hz (20 times per second) to 200Hz Increasing frequency (Hz) causes the current to change direction more often, which means that it spends less...
  • Page 18 TIG WELDING GUIDE Razor AC TIG Welding - AC Wave Balance Control 32OAC/DC TIG-MMA AC (alternating current) enables us to TIG weld non ferrous alloys like Aluminium, Magnesium and Aluminium Alloys. These materials have an insulating surface oxide layer that melts at a higher temperature than the base metal making it difficult to weld the base metal if the oxides are not removed.
  • Page 19 TIG WELDING GUIDE AC TIG Welding - AC Wave Balance Control Razor 32OAC/DC TIG-MMA In older machines, a balanced current output wave was achieved using a large number of capacitors in series or a battery in the welding circuit. Modern TIG power sources use electronics to create and maintain a balanced wave and now most AC TIG power sources produce a square wave current output.

EXAMPLE OF PULSE AC TIG WELDING - SETUP PARAMETERS: Material = Aluminium x 3.0mm / Tungsten Electrode = 2.4mm Zirconiated / Gas = Argon The following steps are a guide as a starting point for you to set the machine up in Pulse mode to give an example of welding in Pulse mode function.
  • Page 21 TIG WELDING GUIDE DC TIG Welding The DC power source uses what is known as DC (direct current) in which the main electrical component known as electrons flow in only one direction from the negative pole (terminal) to the positive pole (terminal). In the DC electrical circuit, there is an electrical principle at work which should always be taken into account when using any DC circuit.

  • Page 31: Mma (Stick) Additional Notes

    MMA (STICK) ADDITIONAL NOTES DC MMA ELECTRODE POLARITY - What is the electrode polarity and why is it important. When using a DC power source, the question of whether to use electrode negative or positive polarity arises. Direct current flows in one direction in an electrical circuit and the direction of current flow and the composition of the elec-trode coating will have a definite effect on the welding arc and weld bead.

  • Page 32: Mma (Stick) Welding Guide

    MMA (STICK) WELDING GUIDE STICK (MMA / Manual Metal Arc) Welding One of the most common types of arc welding is manual metal arc welding (MMA) or MMA welding. An electric current 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 flux 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.
  • Page 33 MMA (STICK) WELDING GUIDE Electrode Selection As a general rule, the selection of an electrode is straight forward, in that it is only a matter of selecting an electrode of similar composition to the parent metal. However, for some metals, there is a choice of several electrodes, each of which has particular properties to suit specific classes of work.
