Q:The normal function of argon arc welding welding, arc not normal, press the switch can hear the fire place in the machine (what is I do not know the name, like the discharge gap? Is the two small pieces of metal plate - like contact not contact place) with loud no problem before, there are sparks. Some people say that the problem is the high frequency don't ask the master, the arc, which is the problem, can repair? Is worth repairing? Can not repair welding repair in our county those people say. Thank god!: Put the appliance (that is, the 2 small metal plate) the gap is great, and then not to high voltage ceramic capacitor discharger beside the blue change.

Q:Argon arc welding machine arc arc is not how ah?: The switch is out of order! Just change a switch. It's 3 dollars

Q:Aluminum welding. Argon arc welding machine can weld aluminum, aluminum welding and argon arc welding which is cheaper: If your welding machine is AC and DC dual-use, that is, WSE can be welded aluminum, AC, DC welding stainless steel. WSE AC DC square argon arc welding machine is a machine.

Q:It's only a small electrical shock when soldering..: Check if the discharge device is sparking or not

Q:Just bought a reallink argon arc welding WS200S, there is a gas delay switch, I do not know how to use, who can answer! Thank you: 2.5S and 5S conversion, how long will it take to use?

Q:The argon arc welding machine ground wire will leak, what's the matter, looking for a long time can not find the reason, have been it several times: Your earth is not grounded, instructions should have positive ground requirements, if the ground, to see whether the welding poor insulation, ignition by high voltage pulse breakdown voltage protection gas ignition, about three thousand, is the General Electric will be pitted, not life-threatening

Q:Inverter type pulse argon arc welding machine, how to be converted into an electric welding machine, the model is WSM-160: Switch to electric welder? This is the electric welding machine originally! You mean the manual arc welding machine that wants to be changed into welding electrode!Since argon arc welding is similar to manual arc welding, it is very simple to change. Remove the high frequency argon arc welding arc and the valves, two of the joint control of welding torch for argon arc welding line short circuit, if needed, then the original grounding screw argon arc welding joint into the ground (ground) with the same joint, convenient welding wire, a manual arc welding machine is the.

Q:What's the difference between argon arc welding machine 380V with two wire input and three wire input?: Two arc welding argon arc welding machine is single-phase 380V.The argon arc welding machine with three wire inputs is three-phase 380V.Three phase argon arc welding machine has good stability. Now the inverter arc welding is the power input mode.Because of the unbalanced voltage of the network, the welding parameters of single-phase arc welding is poor. Mainly old-fashioned frequency AC arc welding machine based. Backward technology.

Q:I have a 380V three-phase DC argon arc welding machine, can not be changed to 220V single-phase DC argon arc welding machine? Thanks for your help!: 380V three-phase argon arc welding machine can not be changed into 220V single-phase, because the 220V voltage can not drive three-phase argon arc welding, so the welder will not work at all.Argon arc welding is a kind of welding technology using argon gas as protective gas. Also called argon gas shielded welding. That is, argon shielded gas is applied around the arc welding, and the air is separated from the welding zone to prevent the oxidation of the welding zone. Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding material to a welding technology of metallurgical bonding.

Q:What are the advantages and disadvantages of the plasma arc welding machine in comparison with other welding methods?: Plasma arc welding, compared with other welding methods, has Plasma arc, also called compression arc, is used for welding. It has high welding temperature, heat concentration, high energy density, high arc stability and good weld formation. It is suitable for welding of ultra thin welding parts and heavy bulky parts. The drawback is that the equipment is complex and demanding of the operator.
