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:I wonder what the formula for calculating the power of electric welding is. There are several gears in the two output, and my calculations seem to be out of order. I think my calculation is wrong. I would like to ask you a complete calculation method of welding power: Is the output of U2=36V, I2=400A, I1=400*36/440=32.73A of input current, which is 14.4KVA, the number of apparent power, it has the number including power loss, if the efficiency is 0.85, its power is 16.5KW, if the efficiency is 0.95, its power is 15.2KW, if the efficiency is low to 0.6, it the power of 24KW.

Q:Single-phase electric only 220V small workshop, argon arc welding machine is put in front of the computer, in the back, do not know what a machine computer black screen, ask the prawns how to solve, argon arc welding power is very small! Only a few dozen W to one hundred W.Welding machine a moment of ignition, the computer black screen. What's the best way to solve it?: It should be possible to load a computer with a UPS

Q:What is the function of an argon arc welding machine with current attenuation function?: Yours is a dual purpose welder. Is used to welding electrode, sometimes the current is small, welding rod is not good, arc will be sticky when. Adjust the thrust, the current is good, the arc started. To put it bluntly is to help lead the arc. Also in use, that is, vertical welding or overhead welding is to help the particles transition. Under normal circumstances, it doesn't help much. Generally do not open. You'd better not open the assembly to increase splash

Q:What kind of antifreeze is used in water-cooled argon arc welding machine in winter?: Choose antifreeze, freezing point, in general, it is recommended that antifreeze freezing point is lower than the local minimum ambient temperature of about 10 degrees

Q:Argon arc welding machine arc arc is not how ah?: 1: switch damage, (replacement) 2: welding machine delay settings (check, delay setting and recovery), there are two possibilities.

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:How to weld aluminum material with argon arc welding machine: No thorium tungsten or cerium tungsten welding steel pole with pure tungsten, alternating current, welding wire and base metal components. Similar aluminum heat quickly, the temperature of the base metal with the welding process in the continuous increase, to grasp the welding speed and wire feeding speed (generally with the welding process, to speed up the best lining pad. Flow) the welding pool of aluminum is not good, not easy to end with the best fusion butt welding arc plate and arc plate. Aluminum easy arcing, should pay attention to stopping.

Q:What is the power of the BX1-315 AC arc welder?: BX1-315 AC arc welding machineBX1-315 adopts movable winding type high leakage reactance transformerAC arc welding machine adjusts the position of iron core by rotating handle, and stepless regulation currentWelding materials for hand welding machine: low carbon steel, medium carbon steel, low alloy steel, welding slag, butt welding, vertical weldingThe ambient temperature of BX1-315 is between -10 degrees C and 40 degrees CAC arc welding works at an altitude of not more than 1000MThe AC power supply voltage fluctuations in manual welding between the rated value + 10%The BX1-315 workplace wind below 1.5 meters / secProduct model:BX1-315Rated output current (A):Three hundred and fifteenInput input voltage (V):Three hundred and eightyFrequency (HZ):50/60Rated input capacity (KVA):Twenty-two point fiveNo load voltage (V):Seventy-sixRated load duration%:Thirty-fiveRated load voltage (V):Thirty-threeCurrent regulation range (A):60-315Use electrode diameter (MM):2.5-4Insulation level:FDifferent brands have some differences!!

Q:Why argon arc welding only fires without current?: There is no argon or ground wire is not connected

Q:What's the reason for this? Tell me about the trouble. I work in argon arc welding, the novice today, dry with a dry suddenly broken, the arc, I thought is a switch or circuit which is broken, later discovered, with tungsten tip with the welding surface contact, causes a spark. What are the reasons for seeking advice?.: First of all, to see if you hit the welding gear, try another gear,If not, check that the high frequency part is faulty,Arcing indicates that the main circuit is not broken
