Northern Tool and Equipment, as well as Industrial Gas and Supply are two excellent sources for this type of product. Sears also sells welders. Online, they are available from Amazon.
Yes, you can weld aluminum with a DC TIG welder using pure tungsten electrodes and argon gas as a shielding gas. However, welding aluminum typically requires an AC TIG welder to produce the best results due to the material's high thermal conductivity.
A dc welder is a lot cheaper by fair of the two
You can find a manual for the Chemetron 300 HF AC DC TIG welder on the manufacturer's official website, where they often provide downloadable PDFs for their products. Additionally, you may find manuals on third-party sites like eBay or Amazon, or through welding forums and communities where users share resources. If those options don't work, contacting Chemetron's customer service directly can also help you obtain the manual.
It produces alternating current AC. It is cheaper to build than a DC or an AC - DC welder. Most electrodes can be used with DC. Some can be used for both. Very few are AC only. DC produces a smoother arc, is easier to strike an arc and most machines in industry are DC. Surprisingly a lot of AC machines are on farms as they were cheaper to buy.
When welding on AC on a TIG welder you have to option to adjust how your arc passes from your torch to your metal and vice versa. This allows you to clawed your puddle clean of contaminants or burn your weld deeper while welding. When set on balanced, the arc equally passes in both directions.
For an AC welder, it is best to use electrodes specifically designed for AC current, such as 6011 or 6013 electrodes. These rods provide good arc stability and smooth welding characteristics when used with an AC welder. Be sure to follow the manufacturer's recommendations for electrode selection based on the thickness and type of metal you are welding.
Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It's used for welding thicker metals of 1/16 inch or greater.
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!
To operate a Lincoln AC-225 welder, a generator with a minimum output of 5,000 watts is typically recommended. This ensures that there is enough power to handle the welder's starting and running requirements. It's also important to check the generator's rated voltage and ensure it matches the welder's specifications, usually 230 volts. Always consult the welder's manual for specific power requirements.
A Lincoln 225 AC welder typically requires a 50 amp double-pole breaker. This ensures sufficient power supply and prevents overloading the circuit. It's important to consult the welder's manual or an electrician to verify the specific requirements for your setup.
That would depend on the model , age and condition or hours .
Buy a new one stupid.
