Page 3: Safety
SAFETY Welding and cutting is dangerous to the operator, people in or near the working area and the surrounding area, if the machine is not correctly operated. Therefore, the performance of welding/cutting must only be under the strict and comprehensive observance of all relevant safety regulations.
Page 4: General Description
GENERAL DESCRIPTION This welding machine is composed of the inverter MIG welder power supply with invariable voltage output external characteristics manufactured with advanced IGBT inverter technology designed by THE company. With high-power component IGBT, the inverter convert the DC voltage, which is rectified from input 50Hz/60Hz AC voltage, to high-frequency 20-50KHz AC voltage;...
Page 5 GENERAL DESCRIPTION Operating environment Adequate ventilation is required to provide proper cooling for the MIG machine. Ensure that the machine is placed on a stable level surface where clean cool air can easily flow through the unit. The MIG machine has electrical components and control circuit .boards which will be damaged by excessive dust and dirt, so a clean operating environment is essential.

Page 9: Installation
INSTALLATION 5.1 MIG Welding Set Up & Operation 5.1.1 Fitting the spool 5.1.1.1 Open the cover door for the wire feed compartment. Remove the wire spool retainer (24) by threading off anti clockwise. 5.1.1.2 Fit the 200mm diameter wire spool to the spool holder, ensuring the end of the wires exits towards the wire feeder from the bottom of the spool.
Page 10 INSTALLATION Warning! - Before changing the feed roller or wire spool, ensure that the mains power is switched off Warning! - The use of excessive feed tension will cause rapid and premature wear of the drive roller, the support bearing and the drive motor. 5.1.3 Loading wire feeder 5.1.3.1 Connect the MIG Torch Euro Connector (28) to the torch socket on the front of the welder (11).
Page 11 INSTALLATION 5.1.5 Setup for MMA/STICK mode operation Note - MMA/Stick Welding requires an MMA lead set. 5.1.5.1 Connect Electrode holder Quick Connector to the positive (+) welding output terminal (12). 5.1.5.2 Connect Earth Lead Quick Connector (30) to the negative (-) output welding terminal (13). See picture below: 5.1.6 Setup for Lift TIG welding operation Note - TIG operation requires an argon gas supply, TIG torch, consumables.
Page 12 INSTALLATION Connection of Shield Gas Connect the CO2 hose, which come from the wire feeder to the copper nozzle of gas bottle. The gas supply system includes the gas bottle, the air regulator and the gas hose, the heater cable should be inserted into the socket of machine’s back, and use the hose clamp to tighten it to prevent leaking or air-in, so that the welding spot is protected.
Page 13 INSTALLATION 5.1.5 Controls for MIG Welding 5.1.5.1 Voltage meter: in MIG mode it shows setting voltage and welding voltage; in other modes no voltage will be showed. 5.1.5.2 Gas selection: CO2--ordinary CO2 gas; MIX--20% CO2 80% argon; FLUX-- flux cored. 5.1.5.3 Function selection: 2T in MIG mode/4T in MIG mode;...

Page 15 INSTALLATION Basic welding guide MIG (GMAW/FCAW) Basic Welding Technique Two different welding processes are covered in this section (GMAW and FCAW), with the intention providing the very basic concepts in using the MIG mode of welding, where a welding gun is hand held, and the electrode (welding wire) is fed into a weld puddle, and the arc is shielded by an inert welding grade shielding gas or inert welding grade shielding gas mixture.
Page 16 INSTALLATION Position of MIG Torch The angle of MIG torch to the weld has an effect on the width of the weld. The welding gun should be held at an angle to the weld joint. (See Secondary Adjustment Variables below) Hold the gun so that the welding seam is viewed at all times.
Page 17 INSTALLATION DISTANCE FROM THE MIG TORCH NOZZLE TO THE WORK PIECE. The electrode wire stick out from the MIG torch nozzle should be between 10mm TO 20.0mm. This discharge may vary depending on the type of joint that is being welded. TRAVEL SPEED The speed at which the molten pool travels influences the width of the weld and penetration of the welding run.
Page 18 INSTALLATION Establishing the Arc and Making Weld Beads Before attempting to weld on a finished piece of work, it is recommended that practice welds be made on a sample metal of the same material as that of the finished piece The easiest welding procedure for the beginner to experiment with MIG welding is the flat position.

Page 23: Caution
CAUTION 1. Working environment 1. Welding should be carried out in a relatively dry environment with its humidity of 90% or less. 2. The temperature of the working environment should be within -10 C to 40 C. 3. Avoid welding in the open air unless sheltered from sunlight and rain, and never let rain or water infiltrate the machine.
Page 24: Maintenance
MAINTENANCE 1. Disconnect input plug or power before maintenance or repair on machine. 2. Be sure input ground wire is properly connect to a ground terminal. 3. Check whether the inner gas-electricity connection is well (esp. the plugs), and tighten the loose connection; if there is oxidization, remove it with sand paper and then re-connect.
Page 25: Daily Checks
DAILY CHECKS To make best use of the machine, daily checking is very important. During the daily checking, please check in the order of torch, wire-feeding vehicle, all kinds of PCB, the gas hole, and so on. Remove the dust or replace some parts if necessary.
