TIG Welders Buyers Guide

The Sealey Buyer Guide to TIG Welders

TIG Welders are suitable for welding a wide variety of metals, such as:
  • Aluminium (AC models only)
  • Copper
  • Titanium
  • Mild Steel
  • Stainless Steel
  • Cast Iron
  • Brass
  • Nickel
  • Dissimilar metals

They create an arc of electricity between their tungsten electrode and the metal workpiece, to create a weld pool. A filler rod is then used to add metal to create the bead which holds together the two metals to be welded. Finally, Argon gas is used to shield the weld from impurities.

Thanks to their superior arc and weld puddle control, TIG Welders allow you to create a cleaner weld, with no smoke or weld spatter. A weld puddle is the pool of molten metal created by the welder, so there is no need for cleaning or grinding the weld when you have finished. This is ideal when the appearance of the weld is important. Such as on sculptures, marine or catering fabrication.

Foot Pedals are popular accessories, as they allow you to heat up or cool down the weld pool. Sealey’s range of Inverter Welders can be used for TIG welding, or for conventional ARC welding by adding the relevant ARC Accessory Kit.

Duty cycle – This applies to all electric welders

The duty cycle of a welder reflects how long it can weld in a 10-minute period before it has to cool down i.e. a 40% duty cycle equates to 4 minutes of continuous welding. The higher you set the amperage, the shorter the duty cycle.

If you plan to carry out a lot of welding, the duty cycle is a very important consideration when comparing welders.

Warranty - Sealey TIG welders are covered by a 1-year parts and labour warranty on the main power transformer.

Safety First! TIG welders create very hot temperatures and emit a very bright light, which can cause severe damage to both exposed skin and eyesight. Therefore, it is essential that the right safety equipment is worn.
