What to look for in a good aluminum TIG Welder?
TIG welders come with a slew of characteristics and specs that might be difficult for a novice or hobbyist to understand. However, knowing these terms may help you make the right choice for which welder is ideal for you. Here are some technical terms that can help you choose.
Amperage
A welder's output is measured in amps or Amperes. A greater amperage indicates that your weld will receive more heat. As a rule, one amp is required per 0.001 inches of metal thickness for steel welding. Other materials, such as aluminum alloy and iron, need more heat to be welded. Therefore, when working with these metals, choose a welder with higher amps.
Duty Cycle
The term duty cycle refers to the percentage of the duration of how long the welder can operate without overheating. Once it reaches this temperature, the machine must have time to cool before being used again.
For example, a tig welder with a 20% duty cycle can only weld for two minutes out of every ten. If you're planning on welding for long periods, make sure your welder has a high duty cycle—around 60% or higher.
Welding Processes
TIG welders can perform AC and DC types of welding. Alternating current (AC) is most commonly used when welding non-ferrous metals like lead and aluminum. It provides a cleaning action that helps to remove oxides that can contaminate the weld. Direct current (DC) is typically used for steel and iron welding, as it provides a stronger weld.
Current Type
The electrical polarity is the direction of where the electrical current flows. Direct current (DC) is when a welding machine sends a direct flow to the electrode and then to itself. However, a DC with reverse polarity does a rotating flow from the machine to the torch and back. While alternating current (AC) alternates the polarities at a rate of 60/s to 120/s
The ideal current for welding steel and iron is direct current (DC). Other metals may also be used with DC. AC is suited for non-ferrous metals like aluminum. A good rule of thumb is to get a welder that supports both AC and DC.
