§1 Safety §1.1 Signal Explanation The above signals mean warning! Notice! Running parts and getting an electric shock or thermal parts will take damage for your body or others. The corresponding notices are as follows. It is quite a safe operation after taking several necessary protection measures. §1.2 Arc Welding Damage ... - Page 4 SAFETY touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or semiautomatic welding gun are also electrically “hot”. ...
- Page 5 SAFETY to be used, including the material safety data sheet and follow your employer’s safety practices. ARC RAYS CAN BURN. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. ...
- Page 6 SAFETY prevent hazardous situation. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside.

SAFETY §1.3 Knowledge of Electric and Magnetic Fields Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). The discussion on the effect of EMF is ongoing all the world. Up to now, no material evidences show that EMF may have effects on health. However, the research on damage of EMF is still ongoing. -
Page 8: Brief Introduction
OVERVIEW §2 Overview §2.1 Brief Introduction The M-Series of MIG, MAG INVERTER arc welding machine adopts the latest pulse width modulation (PWM) technology and insulated gate bipolar transistor (IGBT) power module, which can change work frequency to medium frequency so as to replace the traditional hulking work frequency transformer with the compact medium frequency transformer. -
Page 9: Working Principle
OVERVIEW §2.2 Working Principle The working principle of M-SERIES arc welding machine is shown as the following figure. single-phase 110 or 220V work frequency AC is rectified into DC（154V）, then is converted to medium frequency AC (about 37KHz) by 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 inductance filtering. - Page 10 OVERVIEW §2.4Principles of welding...

THANK YOU FOR USING OUR PRODUCTS §5.2 Troubleshooting All welding machines have undergone 100% inspection before leaving the factory. Disconnect power cord from LINE before any trouble shooting and only professional maintenance personal should perform any action on the machine! Item Trouble Reasons... - Page 18 THANK YOU FOR USING OUR PRODUCTS §5.3 Wire Feeding Maintenance The welding wire must travel smoothly and freely from the spool all the way to the weld pool for controlled welding. Poor welding performance is many times a result of mechanical feeding problems with the wire through the torch.
- Page 19 THANK YOU FOR USING OUR PRODUCTS §5.4 Changing the Feed Roll The wire feed roller is factory set for welding filler wires 0.8 – 0.9mm (.030” - .035”). The roller has a 0.6mm (.023”) diameter groove on the other side; therefore, the feed roller side must be changed if you use 0.6mm thick filler wire.
