Page 7: Brief Introduction
Brief Introduction Grand Arc series of welding machines adopt the latest Pulse Width Modulation (PWM) technology and the Insulated Gate Bipolar Transistor (IGBT) power modules. It uses switching frequencies in the 20KHz-50KHz ranges so as to replace the traditional line-frequency transformer type welding machines. So, machines are characterized with portability, small size, lightweight, low energy consumption and noise, etc. -
Page 8: Volt-Ampere Characteristic
Volt-Ampere Characteristic Grand Arc series of welding machines has excellent volt-ampere characteristic. Referring to the following graph. In MMA welding, the relation between the rated loading voltage U2 and welding current I2 is as follows: When I2≤600A， U2＝20＋0.04 I2 （ V） ； When I2＞600A， U2＝44 （ V） .

Installation & Operation Connection of output cables two sockets are available on this welding machine. for MMA For MMA welding the electrode holder is shown be connected to the positive socket, while the earth lead (work piece) is connected to the negative socket, Welding this is known as DCEP. -
Page 11: Operation For Mma Welding
(1) According to the above method to install is correct, turn the power switch, so that the power switch is “ON” position, then the power indicator light switch on, the fan comes on, the device work properly. 3.2.2 (2) Select the MMA function with the LIFT TIG/MMA selector switch. Operation (3) Set the welding current relevant to the electrode type and size being used as recommended by the electrode manufacturer with the knob. - Page 12 ● 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 and becomes the deposited weld metal.

3.2.4 Welding Funda- Electrode Selection mentals 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. - Page 14 Trouble Possible Reason Suggested Remedy Check earth lead is connected. Incomplete welding circuit Check all cable connections. Check that the machine is switched No arc No power supply on and has a power supply Check the MMA selector switch is Wrong mode selected selected Arc length too long...
