If the feed is too fast it will push your hand away from the work. If the feed is too slow the wire will burn back to the tip.
Set your wire speed to your voltage setting by ear. When you hear the sound of bacon sizzling in the pan you are set. If you hear a lot of popping the speed is to fast. If it is to slow you will have trouble keeping the arc going. If you are welding at 23 volts start with a wire speed of about 140 IPM (Inches Per Minute). That's ball park, since every machine and every person is different.
The wire feed welder is a MIG welder.
there is no such thing as a gasless mig welder because mig stands for metal inert gas. you must have tubular wire which has the flux in the wire. i would say you should get some s wire to do the job
5 mm
Yes it can. I use flux core wire because there is no need for gas with flux wire.
Depends on a lot of things. Slickest work, but most expensive - TIG. Cheapest - arc (stick) welder. Reasonably user friendly and inexpensive - wire-feed arc/ MIG welder.) Most versatile - Oxyacetylene. Oxy will give have the biggest heat affected zone and is the hardest to use (IMO). If your kart is really thin wall tubing you can forget about the stick welder and even the MIG will be quite tricky.
No, the wire will overheat.
A number of factors go into this: base material thickness, joining material thickness, wire thickness, shielding gas composition, angle of weld, etc. The best way to determine this is to measure your material, then open your MIG welder, find the wire size of the spool, and read the chart inside of the MIG Welder door.
Mig (GMAW) has almost replaced Stick (SMAW) in industry. Small machines can weld thin materials and larger machines weld metals of unlimited thickness. Mig is easy to use and has less waste (no stubs) than stick. Flux core wire produces a slag covering but bare wire w/gas leaves a clean weld.
can weld aluminium with a mig or tig welder
Aluminum is one example of a metal that cannot be MIG welded and must be TIG welded. The limitation of MIG is usually the heat it can produce versus thickness of the material. One quarter-inch thickness is usually about as thick as you can weld with either MIG or flux-core wire feed welders. Anything else will require the heat energy available with a stick welder.
A clarke mig welder is considered a top of the line welder and can be purchased at specialty welding stores or even at hardware stores like home depot or menards. They can also be bought online.
