Ensure to prepare fire extinguisher just in case. To prevent the rotating moving parts wounding Must not make fingers, hair and clothes close to the cooling fan and wire feed roll and other rotating parts. When feeding wire, must not make the welding gun end close to eyes, face and body to avoid wire damaging person.
Precautions of electromagnetic compatibility 1. Overview Welding brings electromagnetic interference. Minimize the interference emission of arc welding equipment with proper installation way and correct application method. The products described in the manual belong to Class A equipment (all occasions except residential area powered by public electrical power system).
Page 8
The arc welding equipment shall be connected into public power supply system with the method recommended by the manufacturer. In case of interference, please take addition preventive measures, such as connecting filter with public power supply system. Ensure to consider power able shielding for fixed arc welding equipment. The power cables can be shielded with the metal pipe or other equivalent methods.
The shielding of surrounding equipment and other cables can reduce the electromagnetic interference. The whole welding area can be shielded for special applications. Main technical information 1. Main technical parameter Model TIG-200 Rated input voltage(V) 1PH AC220V±15%,50/60Hz Rated input power(KVA) Rated input current(A) No-load voltage(V) Output current(A)
Installation 1. Environment Install in a dry environment with humidity less than 90% at 20℃ and 50% at 40℃. The temperature should be in the range of -10℃-40℃ when welding, and -20℃-55℃ for storage and transportation. Shelter the machine from direct sunshine and rain. Avoid raindrops. ...

2.3 Cold welding Tightly connect the air pipe with the air inlet of the welding machine rear plate;The air supply path should include gas bottle, argon decompression flowmeter and air tube. The connecting part of the air tube should be tied tightly with hose clamp to prevent leakage and air entry.
Welding machine precautions and maintenance 1. Safety points The welding machine is quipped with overcurrent and overheat protection circuits.When the gird voltage,output current and internal temperature exceed the set standard the welding machine will automatically stop working,but excessive use(such as excessive voltage) will still lead to welding,The machine is damaged,so you still need to pay attention to the following: ...

It is forbidden to use the welding machine for thawing pipes。 The back of each welding machine is attached with a ground screw, and marked with a ground mark. Before use, select a cable with a section greater than 2.5mm2 and ground the welding machine shell reliably to release static electricity or prevent accidents that may occur due to electricity leakage.

in dry condition. 3. Before maintenance Warning: Blind experiments and imprudent overhaul could lead to the expansion of failure,and ! difficulty for a formal maintenance.Electronic equipment in the state of the exposed part of a voltage can lead to dangers.any direct or indirect contacts may lead to electric shocks incidents,and serious electric shock will cause death!!! Attention:During the warranty period, if not allowed by this Company, if there is any wrong maintenance to any fault of the welding power source, the suppliers will not provide free repairs.
