providing that you have the proper tig welding equipment (torch,tungsten and inert gas) it is simply switching the polarities on the welding machine. the lead to the torch will be negative and the ground will be positive this is called straight polarity,this application will work with most metals except aluminum which requires a high frequency welding machine A couple of things a home built TIG machine will not have. 1) High frequency start - you will have to scratch start which could leave tungsten contamination in the weld 2) Remote control - one of the nice things about most TIG machines is the ability to adjust the power/heat on the fly. 3) Gas solenoid valves - TIG is usually done with pure Argon gas. This is probably the most expensive shielding gas in normal use. As a result, its usually nice to shut if off. TIG machines have solenoids that do that with timers that shut the gas flow off after a few seconds. I would highly recommend you search "Craigslist" for a used Miller TIG. Miller because you can still get parts for them if necessary (I have a 30year old unit going strong!). Just be aware they tend to be heavy with large copper coiled Transformers inside. From a cost standpoint, the regulator, gas bottle, torch etc. could set you back $500. An old Miller Dialarc HF is probably that much ready to run (HF = High Frequency starting circuit).
when refering to tig welding, tig stands for Tunsten Insert Gas
If it can be welded it can probably be TIG welded. Exceptions would be metals with a low melting temperature ie: lead, tin, zinc etc.
Ctw
produces extremely straight and even welds
I wouldn't call TIG unique as it was developed to replace Oxy-Acetylene welding. Basically you use a heat source to melt the base metal and either fuse or add filler to complete the weld. TIG, originally called Heliarc (Helium - electric arc), was developed sometime around WWII to weld Aluminum. Helium was used to protect the molten puddle. Since then Argon has become the primary gas sometimes mixed with Helium. Almost any type of metal can be welded with the TIG process. Except for fuse welding it is a two handed operation whereas MIG and stick welding can be performed single handed. One thing that is unique is that with the addition of a foot pedal you can control the Amperage as you weld. many planes were produced here at Wright with gas welded Aluminum most was done with Hydrogen Oxygen torch taking care to have a reducing flame
No , although Co2 may be used , along with other gasses , a welder using this process is not considered a Co2 welder . TIG stands for tungsten Inert Gas , so the welder is considered / called a TIG Welder.
a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas
TIG welding, i.e. tungsten inert gas (TIG) welding, is primarily used in the aerospace industry. Thus TIG welder would typically find employment there.
can weld aluminium with a mig or tig welder
The wire feed welder is a MIG welder.
Tig, mig , or If you are as good as me stick welding will all work
I don't see why not. If you can see well enough to use the equipment or handle OFC and Stick/MIG/TIG then you should be fine.
Any D C stick welder can be adapted to TIG welding most metals (not Aluminum). Purchase a torch, regulator/flowmeter and hose, rent a cylinder of gas (preferably Argon) . Connect the TIG lead to the negative - post, your ground cable to the positive + post, set the flow at 15 - 20CFM and you're in business. You will have to scratch start to establish an arc. You will also have to guess where to set the amperage control on the machine. Practice will help with this.
the best way to get a good looking/ strong weld on aluminum is using a tig welder it is also possibles with a mig welder but for best results recommend a tig welder with HF
It does not cost anything to get a job in tig welding. There are many companies that are hiring an experienced tig welder. You can find many of them online.
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 Unless you have a newer model welder that is CC & CV, and then they do not do aluminum unless you get into the high end inverter models. Wire welding uses the CV (constant Voltage) and tig is CC (constant current)
