SAFETY §1 SAFETY Notice: The instructions are for reference only. The manufacturer reserves the right to explain the differences between the description and the product due to product changes and upgrades! The device is manufactured using state-of-the-art technology and according to recognised safety standards. If used incorrectly or misused, however, it can cause: l Injury or death to the operator.
Page 7
SAFETY Excessive ambient temperature will cause the machine heat dissipation is not smooth, so that the internal components of the machine heat seriously. Usually the maximum operating temperature is 104°F (40°C). Low temperature may lead to performance degradation or damage of components inside the product, resulting in ice inside the water tank.
Page 8
SAFETY Many harmful phenomena, such as noise, bright light and harmful gas, will inevitably occur in the welding process. In order to avoid harmful By product phenomena causing harm to the human body, it is necessary to make corresponding preparations in advance. Arc rays from the welding process produce intense visible and invisible ultraviolet and infrared rays that can burn eyes and skin.
Page 9
SAFETY Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. l Do not breathe the smoke and gas generated whilst welding or cutting, keep your head out of the fumes. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone.
Page 10
SAFETY Flying sparks from the welding arc, hot work piece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating or fire. l Welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.
Page 11
SAFETY cylinder outlet valve and gas regulator. Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition.

SUMMARY §2.3 Duty cycle & Over heat The letter “X” stands for duty cycle, which is defined as the proportion of the time that a machine can work continuously within a certain time (10 minutes). The rated duty cycle means the proportion of the time that a machine can work continuously within 10 minutes when it outputs the rated welding current.
SUMMARY §2.5 Volt-Ampere Characteristic TIG AC/DC PULSE welding machine has an excellent volt-ampere characteristic, whose graph is shown as the following figure. The relation between the conventional rated loading voltage U and the conventional welding current I is as follows: When I ≤600A, U =10+0.04I...

INSTALLATION & OPERATION AC Square Wave Focused arc for maximum penetration, fast travel speed with best directional control. AC Sine Wave Welding Output Traditional AC TIG welding wave form. Quieter, ‘soft’ arc characteristic. AC Triangle Wave Welding Output Reduced heat input for same current setting. Especially useful for welding thin metal. DC Welding Output It is suitable for DC TIG welding.
Page 24
INSTALLATION & OPERATION TIG Parameter Setting (18) Pre gas flow setting indicator 1) Pre-flow controls the period shielding gas will flow for when the torch is triggered before the arc starts. This purges the work area of atmospheric gas which could contaminate the weld before the weld starts.

Contact with the work piece must be firm contact with clean, bare metal, with no corrosion, paint or scale at the contact point. (3) Connect the electrode lead to “+”, tighten clockwise;...
INSTALLATION & OPERATION (2) Set to ‘MMA’ welding mode. (3) Set the welding parameters as required using the parameters control knob (following the instructions in the previous section). (4) Place the electrode into the electrode holder and clamp tight. (5) Strike the electrode against the work piece to create and arc and hold the electrode steady to maintain the arc.
Page 31
INSTALLATION & OPERATION ● 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. ●...
Page 32
INSTALLATION & OPERATION Covered electrodes serve many purposes in addition to filler metal to the molten pool. These additional functions are provided mainly by the covering on the electrode. §3.3.4 MMA Welding Fundamentals n 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.
Page 33
INSTALLATION & OPERATION the current set too low, difficulty is experienced in striking and maintaining astable arc. The electrode tends to stick to the work, penetration is poor and beads with a distinct rounded profile will be deposited. Too high current is accompanied by overheating of the electrode resulting undercut and burning through of the base metal and producing excessive spatter.
INSTALLATION & OPERATION shearing, machining, flame cutting and others. In all case, sedges should be clean and free of any contaminates. The type of joint will be determined by the chosen application. §3.4 Installation & Operation for TIG welding §3.4.1 Set up installation for TIG Welding (1) Insert the earth cable plug into the positive socket on the front of the machine and tighten it.
INSTALLATION & OPERATION Regulator. Check for Leaks! (8) Connect the gas line to the machine inlet gas connector via the quick push lock connector located on the rear panel. Check for Leaks! NOTE: Air cooling mode without cooling device,and the water pipe is not needed for the air cooling mode.

INSTALLATION & OPERATION minutes. This allows the fan to run and cool the internal components. (9) Switch the ON/OFF Switch to the OFF. §3.4.3 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).
INSTALLATION & OPERATION powerful arc with more heat so more current (amps) are necessary to melt the material. §3.4.4 TIG Welding Fusion Technique Manual TIG welding is often considered the most difficult of all the welding processes. Because the welder must maintain a short arc length, great care and skill are required to prevent contact between the electrode and the work piece.
INSTALLATION & OPERATION fed into the leading edge of the molten pool, the arc will melt the filler wire into the weld pool as the torch is moved forward. Also a dabbing technique can be used to control the amount of filler wire added, the wire is fed into the molten pool and retracted in a repeating sequence as the torch is moved slowly and evenly forward.

INSTALLATION & OPERATION users have switched to other alternatives. Regarding the radioactivity, thorium is an alpha emitter but when it is enclosed in a tungsten matrix the risks are negligible. Thoriated tungsten should not get in contact with open cuts or wounds. The more significant danger to welders can occur when thorium oxide gets into the lungs.
Page 40
INSTALLATION & OPERATION Lanthanated (Color Code: Gold) Lanthanated tungsten electrodes (AWS classification EWLa-1.5) contain a minimum of 97.80 percent tungsten and 1.30 percent to 1.70 percent lanthanum, and are known as 1.5 percent lanthanated. These electrodes have excellent arc starting, a low burn off rate, good arc stability, and excellent re-ignition characteristics.
INSTALLATION & OPERATION §3.4.6 Tungsten Preparation Always use DIAMOND wheels when grinding and cutting. While tungsten is a very hard material, the surface of a diamond wheel is harder, and this makes for smooth grinding. Grinding without diamond wheels, such as Aluminium oxide wheels, can lead to jagged edges, imperfections, or poor surface finishes not visible to the eye that will contribute to weld inconsistency and weld defects.
Page 42
INSTALLATION & OPERATION Electrode Included Angle/Taper - DC Welding Tungsten electrodes for DC welding should be ground longitudinally and concentrically with diamond wheels to a specific included angle in conjunction with the tip/flat preparation. Different angles produce different arc shapes and offer different weld penetration capabilities.
