use a xx1x electrode such as a 6010 or 7018. i like around 77-82 amps for a 6010. point the rod about 5 degrees down and do small circles up while watching your puddle to maintain a consistent bead. start your tie ins a half inch above where you finished then quickly work your way back down to tie in and continue your progress up.
can weld aluminium with a mig or tig welder
SP welder means Structural purpose welder.
The five essentials of arc welding include a power source, which provides the necessary electrical energy; an electrode, which melts to form the weld pool; a workpiece, the material being welded; shielding, which protects the weld from contamination; and proper technique, which involves the welder's skill in manipulating the electrode and controlling the weld bead. These elements work together to ensure a strong and effective weld.
The proper ampere rating of a circuit breaker for an electric arc welder depends on the arc welder. Each is different. Look at the nameplate on the arc welder and choose the circuit breaker and wiring accordingly.
Weld
Yes, If you weld on a vehicle with any welder it can not only damage the computer but other electrical parts as well. Easy fix,,,disconect neg wire on battery wait 30 seconds before welding, when done put neg cable back on...thats it
the only way you can weld aluminum is with AC current and high freak setting on the welder , if your welder does not have theses setting then it will not weld aluminum. Good answer! AC is a must! The only other way is if you have an oxy/ace setup (very low psi) or alot of mapp gas, but you have to spread a flux paste on the material (looks like drywall mud) EXTREMELY MESSY!
it welds
In order to weld pieces of 6mm steel you can use any type of welder. Depending on how strong and how pretty the weld needs to be will determine the type of welder you choose.
You might find where it was made and contact the state museum to see if they want it for display purposes.
why is it important only to strike the arc in the weld joint
Yes you will not get a "good" weld and it will not be strong The filler electrode used by TIG welder is usually bare and need a shield gas to shield off the atmosphere. Without shield gas, air gets into the molten weld usually produce defects called porosity (air pocket). Your finished weld is defective may not meet the strength. Without a shielding gas you will need more power to establish an arc and the weld puddle will be extremely contaminated (oxidized). The electrode (tungsten) will also be contaminated. You will find the arc wandering all over the place. Use a stick welder instead!
