  • Page 5 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 6 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 7 SAFETY Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases.  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 8 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.  Welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

    OVERVIEW fanrunning. When operating the machine again, the welding output current or the duty cycle should be reduced. §2.5 Working Principle The working principle of BT MIG series welding machine is shown as the following figure. Single-phase 110V/230V work frequency AC is rectified into DC (320V), then is converted to medium frequency AC (about 20KHz) by 1st inverter device (IGBT), after reducing voltage by medium transformer (the main transformer) and rectifying by medium frequency rectifier (fast recovery diodes), and is outputted by two ways.

These additional functions are provided mainly by the various coverings on the electrode.
  • Page 33 INSTALLATION & OPERATION current is accompanied by overheating of the electrode resulting undercut and burning through of the base metal and producing excessive spatter. Normal current for a particular job may be considered as the maximum, which can be used without burning through the work, over-heating the electrode or producing a rough spattered surface.

    INSTALLATION & OPERATION (amps) are necessary to melt the material. LIFT ARC IGNITION for TIG Welding Lift Arc is a form of arc ignition where the machine has voltage on the electrode to only a few volts, with a current limit of one or two amps (well below the limit that causes metal to transfer and contamination of the weld or electrode).
  • Page 38 INSTALLATION & OPERATION TIG Welding with Filler Wire Technique It is necessary in many situations with TIG welding to add a filler wire into the weld pool to build up weld reinforcement and create a strong weld. Once the arc is started the torch tungsten is held in place until a weld pool is created, a circular movement of the tungsten will assist is creating a weld pool of the desired size.

  • Page 39: Tungsten Electrodes

    INSTALLATION & OPERATION §4.2.4 Tungsten Electrodes Tungsten is a rare metallic element used for manufacturing TIG welding electrodes. The TIG process relies on tungsten’s hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius.
  • Page 40 INSTALLATION & OPERATION Ceriated (Orange) Ceriated tungsten electrodes (AWS classification EWCe-2) contain a minimum of 97.30 percent tungsten and 1.80 to 2.20 percent cerium and are referred to as 2% ceriated. Ceriated tungsten performs best in DC welding at low current settings. They have excellent arc starts at low amperages and become popular in such applications as orbital tube welding, thin sheet metal work.

(12) Press and hold the manual wire button to feed the wire through to the torch neck, release the manual wire button when the wire exits the torch neck.
  • Page 46 INSTALLATION & OPERATION Solid Hard Wire - like Steel, Stainless Steel requires a drive roller with a “V” shape groove for optimum grip and drive capability. Solid wires can have more tension applied to the wire from the top pressure roller that holds the wire in the groove and the “V” shape groove is more suited for this.

  • Page 47: Wire Installation And Set-Up Guide

    INSTALLATION & OPERATION §4.3.3 Wire Installation and Set-Up Guide Again the importance of smooth consistent wire feeding during MIG welding cannot be emphasized enough. The correct installation of the wire spool and the wire into the wire feed unit is critical to achieving an even and consistent wire feed. A high percentage of faults with MIG welders emanate from poor set up of the wire into the wire feeder.
  • Page 48 INSTALLATION & OPERATION (5) Feed the wire through the drive roller (6) Lock down the top pressure roller and and into the outlet guide tube of the wire apply a medium amount of pressure using feeder. the tension adjustment knob. (7) Check that the wire passes through the center of the outlet guide tube without touching the sides.
