2. Rigorous process design, regardless of harsh environments or reload will operate properly

3. End voltage and current adjustable, regulate that help to make up the crater defects at the end of welding

4. With voltage and current adjusted separately/simple synergic function, whether newbies or skilled welders can easily operate.

Tips: If welding cable is longer than 5m, dual-driven wire feeder will be a better choice to reach better welding performance.

Q:How to use invert arc welding machine?: Note: when the first input line arc welding inverter is 220 volts if input is connected with a live wire, a zero line, if the input is 380 volts, is connected with 3 wire grounding, a yellow green color line welding machine shell and distribution box;At the same time, because the output of inverter welding machine for DC output, so that the output end of the wiring direction, normally welding positive line welding machine output, anode ground wire welding machine output, so called DCRP, is a common MIG welding normal connection; welding for DC output the electricity does not zero breaking arc, so not only can use the common acid electrodes, can also use the low hydrogen welding electrode and stainless steel and cast iron welding rod, the output current of more than 630 can also be used to make carbon arc gouging;The other is that when welding DC and AC is different can produce partial arc processing General in addition to changing the grounding position and change the electrode tilt direction to offset the blow, is slightly reduced in current, because the degree of current and magnetic blow is directly proportional to the square of the current, so slightly reduced, magnetic bias it may greatly improve the degree of blowing.

Q:How does argon arc welding gas?: Do not weld in a windy place and turn down the argon to the point where the quality of the welding is not high enough to be welded. Can also put some small gas delay time, and advance aspirated can turn off the machine.

Q:What is the problem of inverter type hand arc welding machine without arcing?: Check the following possible: diode bad, circuit board bad, power supply phase missing, power supply insurance burned, the template is bad.

Q:How do we need welding with argon arc welding machine, and what tools do we need? Please explain in detail, satisfaction added 10 points: For mature argon arc welders, it is not very difficult to solder aluminum. The main points are as follows:1) AC argon arc welding machine shall be used. The use of a cathode crushing needle in the process of welding produces three aluminium oxide (two aluminum oxide).2) the choice of black glass. Should be more than you usually weld stainless steel lenses plus one to two, in order to better see the molten pool.3) suitable material selection. Select the suitable filling material according to the aluminum material.4) the choice of gases. Rich argon gas (nitrogen + argon) and argon gas can be used in two ways.5) current selection. According to personal habits.

Q:What does the 315 argon arc welder cool with water?: 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.

Q:The length of wire on the two side of arc welding machine shall not be more than several meters: The length of the wire is 100 meters. But the welder must use BX1 or BX3, ZX5 and so on. That is to say, the output voltage should be higher. General 75-80V is easy to use.

Q:Excuse me: how about the power of 315 DC arc welding machine?: It depends on how much current work you use, the 315 welding machine in general election 100A--250A, work voltage of 38V, three welders work at the same time the maximum power: 250*38*3=31 kW, select 35 kilowatts of generators enough.

Q:Reallink Christie and argon arc welding machine which is good, what are the advantages: Christie and Ruiling is not the 'brothers alone' as far as I know: reallink is the founder of Mr. Qiu Guang, then (now Christie's boss) A and Qiu Guang cooperation, A money, Qiu light technology. After separation, was also playing a lawsuit, finally to Qiu Guang reallink. Behind the A made a new brand of Christie

Q:Can argon arc welding machine be used as DC welding machine?: The DC welder can not be used as an argon arc welding machine.DC welding machine, in broad sense, as long as the output is direct current, belong to DC welder.Including two welding electrodes, hand arc welding, DC TIG welding machine, etc..Narrow sense, DC welding machine is: welding rod hand arc welding machine.Only welding rod arc welding machine, using strike arc, can be used as simple tungsten argon arc welding, the disadvantage is that the need for external gas control system. The larger the short-circuit current is, the more serious the tungsten electrode burns. The weld is easy to clamp tungsten.

Q:Two can welding machine be used as argon arc welding machine?: Can. 2 welding machine is also a DC welding machine, but the no-load voltage is higher than our general motor, very unsafe, not recommended. Argon arc welding is divided into melting pole and non melting pole (that is manual tungsten inert gas arc welding). If you choose melting pole, please use AC welder.
