welded by several welding processes including the arc welding processes resistance welding electron and laser beam welding friction welding and brazing For any of these processes joint surfaces and any filler metal must be clean The coefficient of thermal expansion for the austenitic types is 50% greater than that of carbon steel andmachine In welding equipment this will typically refer to levels of voltage current arc length or wire feed speed Set Value A value chosen and set by the operator or by an automatic system Reference Value The value indicated by measurement with a precision instrument the test instrument for comparison to a displayed value or set value Arc Force Min Max SMAW Arc Force Max 10 15 30 40 50 60 70 80 90 DC Amps DC Volts Volt/Amp Curve CC % Duty Cycle Welding Amps Duty Cycle Chart Rated Output Performance Data 2 Control Panel Gold Star ® Specifications Subject to change without notice 1 Arc Force DIG Control 2 Output Switch Here is a detailed stick electrode welding amperage chart Whether you are a novice welder or a seasoned pro this chart is a handy tool to keep close while welding This bulletin is written with the arc welding operator in mind containing both mandatory safety practices and those based on shop experience Be sure to read ANSI Z49 1 and refer to the other publications listed at the end of the bulletin for more detailed information on specific topics of arc welding safety as well as theDirect current welding machines provide a steady current in one direction The direction of flow called polarity is determined by how the leads are connected to the welding machine DC with electrode positive is the polarity typically used for shielded metal arc welding The Welding Circuit Apr 30 Welding machines are classified as constant voltage or constant current Constant current machines stick and tig mostly try to keep the current more or less constant The voltage will vary mostly based on how short an arc you hold A short arc reducing the resistance of the arc and hence the voltage For MIG/MAG a connection on the drive rolls back at the wire feeder will suffice However the voltage measured across the arc will be lower than that measured across the power source terminals possibly by several volts depending on the length and diameter of the welding cables and the amplitude of the welding current Fig 2 The unique characteristic of TIG welding when it comes to amperage is that the foot pedal on the TIG welding machine controls the amperage needed in the weld per the user’s input The foot pedal starts at 0 amps in the resting state and will gradually increase in amperage as the welding operator pushes the foot pedal down to a certain limit


Arc Machines Inc has decades of experience leading the orbital welding industry—and we put that expertise to work for you Reach out today for any questions on our top of the line products training programs or customization abilities Fig 2 Voltage measuring technique a Connection to the back of the TIG torch b Connection to the back of the MIG gun Care should be taken when measuring arc voltage in TIG welding as the high voltage used for starting the arc may damage the instrumentation unless it is specifically designed for arc monitoring The right question would be… what& 39 s the power needed and what type and size of two materials u need to weld I can have V power supply and a capability to source A of current to practically weld anything E ALUMINUM ARC ELECTRODE 1/8" ELECTRODE PART NUMBER CHART ELECTRODE DESCRIPTIONS TYPE Mild Steel Current AC/DC All position electrode Use when you are unable to prepare a welding surface Its deep penetration allows welds through rust scale oil and dirt TYPE Mild Steel Current AC/DC All position electrode Nov 13 The heat affected zone HAZ is much greater with shielded metal arc welding SMAW and much more concentrated with GMAW On a frame you want as little heat as possible If you can’t gas metal arc weld it then I would suggest using a small diameter electrode such as 75 in diameter Electrodes like or would be good because OXARC® Inc provides welding and industrial supplies safety products & training as well as industrial medical and specialty gases OXARC is a family owned business operating in 21 locations across the Northwestern USA since OXARC Fire Services includes mobile fire extinguisher sales service & training and fire suppression systems Arc Welding Advantages The process gives high deposition rates Welding speed is high Wire consumption is low The consumption of electrical energy is low as a maximum of 97 % of heat energy can be utilized Any length can be welded without any interruption High quality Welds are achieved with no fusion defects no porosity and slag inclusions There are various types of sensors available for robotic arc welding applications Depending on their functions the sensors are classified into two categories process and geometrical I am working on an arc welding machine I would like to measure the arc voltage between the metal part I do weld and the welding machine There sparks a high voltage around V or more when the welding machine is first ignited Then it settles down to 10 15 volts which is the most I interest in I tried voltage divider method

If your tig welding steel with argon your AV should be 9 to 11 volts If your Tig welding aluminum it will be around 10 13 If you are tig welding with helium it will be 19 23 volts It you stick weld w/ it will be even higher like 26 volts Aug 05 Stick Welding Equipment Stick welding equipment is the simplest of all the electrical arc welding processes A Stick Welder has four parts A constant voltage CV power supply/Stick Welder Electrode holder/rod holder Ground clamp Stick welding electrodes/rods to weld with Table 1 Welding Current Data Welding Voltage Welding voltage primarily controls the arc length which is the distance between the molten weld pool and the wire filler metal at the point of melting within the arc As the voltage is increased the weld bead will flatten out more and have an increasing width to depth ratio Sensors for arc welding are devices which – as a part of a fully mechanised welding equipment – are capable to acquire information about position and if possible about the geometry of the intended weld at the workpiece and to provide respective data in a suitable form for the control of the weld torch position and if possible for the arc welding process parameters However if it is set for amps the arc voltage will be 26 volts and the duty cycle is % Unlike a GMAW welder I can only set the current on my TA Arc voltage is determined by the machine depending on the variables I introduce with the way I maipulate or fail to manipulate the torch! Them be my 2¢!Arc welding machines have 3 different currents DC DC and AC As for the voltage I personally have never payed attention to the voltage output of my welding machine I use the amps to control my heat the voltage output is right above the amp settings and I know it varies with how much amps you’re putting out SIMDER ARC WELDING MACHINE ACCESSORIES Stick Welding Rod Electrode Holder cable With strong clamping force suitable for a welding arc Arc Welding Ground Clamp t cable It has a large contact area for an effective ground connection Voltage power adapter cable V& V To be used to convert voltage if you need current and voltage in arc welding • What is displayed on the welding equipment or via external sensors and how it is measured • Demands and connection points of external measuring devices The guideline is mainly intended for companies that need to check displayed values of voltage and current on their welding equipment or connect externalArc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal and the melted metals when cool result in a binding of the metals It is a type of welding that uses a welding power supply to create an electric arc between a metal stick " electrode " and the base material to melt
