  • Page 3: Safe Item

    Safe Item Please do the best safeguard when operator does the welding work, welding work will be bringing the harm to you and others. Regarding the detailed information regarding the accident when welding, please check the manual carefully. There is necessary to have a train for the welding work operator, in order to use this machine safely.

  • Page 4: Properties

    Product Brief INMIG IH gas shielded welding machine is the inverter welding machine with the international advanced inverter technology. The general principle of it is to make the 50Hz/60Hz AC current into DC current, and make the DC current into high frequency AC current basing on the high power electronic element IGBT, whose frequency could be 20KHZ, reducing voltage and rectification Character:...

  • Page 7 1. input wire connection There is a power wire for each machine. 180/200’s power wire should be connecting to AC 220V; 250’s power wire should be connecting to AC 220V, there is no phase order for three wires . 2. output wire connection Please connect the gas cylinder which is with the gas gauge to the CO2 enter door at the rear of machine through gas tube.

  • Page 8: Operation

    Gas cylinder assemble Please connect the gas cylinder which is with the gas gauge to the CO2 enter door at the rear of machine through gas tube，and fasten it by gas tube lock Please pay attention: 1. Please keep the gas cylinder far from high temperature area, and all possible high temperature places, in order to avoid increasing the gas pressure for accident.

  • Page 12 1. Environment The welding operation shall be operated in a relatively dry environment, and the air humidity should not exceed 90 percent. (2) The ambient temperature should be between -10 and 40 . (3) Do not weld under the sunlight or in the rain, and do not let water or rain go into welding machine.
  • Page 13 (4) There is one grounding screw on the back of every welder with the grounding mark. Before use, selecting one cable with the cross section of more than 4mm 2 , connect the shell of welding machine to ground to discharge electrostatic or avoid possible accidents due to current leakage.

  • Page 14: Attention

    The repairing principle of the welding machine should be made by our company and the user can solve the problems met in using it under the direction of our company. 1. Issues to pay attention It should rivet the tag of equipment number on the shut of the casing, or the inner elements might be damaged.
