Each Miller welder has its own unique ID number, which is called the welder serial number. Because Miller only allows qualified welders to leave the factory, it can also be used as a product certificate. The welding machine serial number consists of two letters and six numbers, where the two letters represent the production year and ABCDEFGHJK respectively represent Arabic numerals: 0 123456789. For example, the serial number of the welder manufactured in 1999 is KK * * * * *, for example, the serial number of the welder manufactured in 2000 is LA * * * * *. Because every welder's information has a computer history record in Miller Factory, the serial number of the welder can be used to get the technical support, warranty application and after-sales service of the factory's complete system, and can be used to check the authenticity of the welder. The authenticity of the welder can be verified by the serial number of the welder. English is Serial. There is no guarantee that the equipment purchased by authorized agents is genuine.
Miller welding machines are divided into silicon rectifier welding machines (such as CP series and MILLERMATIC series), thyristor welding machines (such as GOLDSTAR series, DELTAWELD series, DIMENSION series and SYNCROWAVE series) and inverter welding machines (such as XMT304, INVISION series, PHOENIX456, MAXSTAY series, chaton 300 and AEROWAVE). The inverter welder is advanced in technology, powerful in function, controlled by computer, good in arc controllability and small in size. It can be used for pulse welding, and is suitable for on-site installation welding, pulse welding and all-position automatic welding. Thyristor welding machine is suitable for welding production line of factory or welding station where welding machine does not move frequently. Silicon rectifier welding machine is simple and durable, suitable for occasions with low requirements for arc control and low price.

According to what standard is Miller welder produced?
Miller welding machine with CE mark is produced according to IEC-974- 1 and EN-60974- 1 standards. Other products are produced according to CSA standards. The factory has ISO900 1 certification.
How long is the warranty of Miller welder?
Miller welder is generally guaranteed for 3 years, IGBT and rectifier bridge for 5 years and engine for 1 year. The welding torch is guaranteed for 3 months. Each welder is accompanied by a user manual, and the seal 2 of the manual is the specific provisions of the warranty. The design life of Miller welder is 12 years, and the actual life can reach more than 20 years. It depends on the use state of the welding machine.
How did Miller welder take the exam?
The product design cycle of milling machine welding machine is generally 3 years. After in-factory testing, target customer application inspection and regional sales inspection, it is included in the official product sales. Welding machine is a formal product, and the functions of welding machine have been strictly tested before off-line, and all qualified products are equipped with product serial numbers. Therefore, the welding machine in the hands of customers is already a qualified product.
What is duty cycle?
The rated load duration is generally expressed as a percentage, such as 60%, 100%, etc. It represents the continuous welding capability of the welder design. The United States adopts the standard test of 10 minute. For example, the rated load duration of the welder is 100% at 300A, which means that the welder can continuously weld when the welding current does not exceed 300 A. When the rated load duration of the welder is 300 a, 60% means that the welder can only continuously weld for 6 minutes and rest for 4 minutes every 10 minute. For the same welder, the greater the current used, the shorter the load duration. Both the introduction and user manual of Miller welding machine have load duration curves, which are easy to find. China, Japan and Europe adopt the standard test of 5 minutes, so the 40% rated load duration of Miller welder is equivalent to the 80% rated load duration of China standard. For submerged arc welding, automatic welding, semi-automatic welding and mass production line welding, the welding current should be less than the current value of the welding machine at 100% load duration, otherwise the welding machine will continue to overheat or burn. In general, the welding current of manual welding should not be greater than the current value when the welding machine has a load duration of 60%. In general, the welding current of spot welding and maintenance should not be greater than the current value of the welder under 40% load duration.
What are the characteristics of Miller's inverter welding machine?

Make Miller's new generation inverter welding machine become the representative of Miller's new technology.
Why do you use XMT304 welding for manual welding, and feel that the weld quality is good and the operation process is simple?
XMT 304 always monitors the arc state with a detection device, helps you adjust it, and makes you feel easy to operate. For example, in a very short time when arcing occurs, it will automatically increase the arcing voltage, so that you can use any covered electrode without worrying about arcing. At the same time, when the arc is about to break or stick, the welder will automatically help you maintain the arc burning. So you think that after using XMT 304, your welding technology far exceeds your existing welding technology.
What do CC and CV mean on Miller welder? What do you mean by communication and DC?
CC, CV means that the output characteristic curve of electric welding machine is constant current (CC) or constant voltage (CV). Welding machines with CC external characteristics can be used for manual welding, TIG welding, thick wire submerged arc welding and carbon arc gouging. Protective welding, filament submerged arc welding, carbon arc gouging. The welding machine with two external characteristics of CC/CV is a multifunctional welding machine, which can be applied to various welding methods. AC is AC and DC is DC. When TIG welding aluminum, aluminum alloy, magnesium and magnesium alloy, AC welder is needed. Multi-wire submerged arc welding also needs alternating current. DC·DC can weld other metal materials.
What is the function of lifting and arc striking?
TIG welding machine generally adopts two arc striking methods, namely scratch method and high frequency arc striking method. The scratch method has tungsten pollution, large tungsten electrode wear and poor welding quality. High frequency is a common TIG arc ignition method at present, but it will cause high frequency interference to other electronic equipment. Lifting arc initiation solves the problem of resorting to two arc initiation methods, and is the most advanced TIG arc initiation method. Miller's TIG welding machines all have this function.
What is static air cooling technology?
Static air cooling means that when the temperature of the welding machine reaches a certain level, the cooling fan automatically starts and the temperature of the welding machine drops to a certain temperature. The cooling fan will automatically turn off. This can reduce the influence of noise, energy consumption and dust on the welder. Miller welding machine has this function.
What is wind tunnel cooling technology?
Miller's inverter welding machines all adopt wind tunnel cooling technology (patented by Miller). This technology means that the cooling air of the welding machine passes through a special air duct without passing through the circuit board and power devices. The heat dissipation of that circuit board and the pow device is carried out through the heat conduction sheet. The influence of impurities on the welder is avoided, and the durability of the welder is solved. It is also convenient for daily maintenance.
Why is Miller's engine welder advanced?
High efficiency and energy saving, suitable for field work. Miller's BIGBLUE series air-cooled engine welding machine is more and more popular with users. Advanced technology means that Miller adopts rotating magnetic field design. The rotating part of the welder only bears the excitation current of 17A, and the welding current is output from the fixed coil, which is output to DC after silicon rectification, without commutator problem. Convenient maintenance and low power demand. The additional power supply adopts special magnetic field, and the welding current does not affect the additional power supply. The engine can be air-cooled or water-cooled. The appearance is sealed, and the circuit board is sealed. Single-sided maintenance, so it is especially suitable for on-site welding.
Is the air-cooled engine more efficient than the water-cooled engine?
Yes! The cooling efficiency depends on the temperature difference. The air-cooled cylinder works at 175 degrees, and the water cooling system works below 100 degrees. Therefore, the efficiency of air cooling is higher than that of water cooling, which requires the radiator to be cooled by air. Water cooling system failures account for 40% of engine failures. Therefore, air cooling can reduce maintenance. No coolant is needed for field welding. Miller air-cooled engine adopts Deutz engine from Germany. This engine is used in German desert tanks.
Does Miller have an inverter welder with an engine?
PIPEPRO 304 has the same welding performance as XMT 304. At present, it is mainly the power supply of automatic pipeline welding equipment.
Does Miller have a double welder for pipe welding?
There is also DU-OP, which is an integrated welder with two multifunctional 300A thyristor welders (size 402) driven by one engine, and can also be combined into a 600A welder. PIPEPRO304 plus XMT304 can also be used as a double welder. Because PIPEPRO 304 can provide 3-phase external power supply, it can drive Miller inverter welder.
