TIG Welders

TIG Welders are ideal for welding metals usually considered difficult to weld. TIG is also renowned for its usefulness for welding thin materials down to a thickness of 0.4mm in materials such as stainless steel, nickel alloys and titanium. TIG DC is usually used when welding ferrous metals such as mild steel, TIG AC is normally used welding non-ferrous metals such as aluminium.

When choosing a TIG Welder

• What power supply voltage do you have ?
• What material are you going to weld ?
• What material thickness are you going to weld up to ?
• what functions would you like eg: pulse etc...
• What is your budget ?

TIG machines are normally equipped with some of the following features:

HF Ignition is a high frequency spark (electronic impulse) created to initiate current flow between the electrode and the work piece. In DC mode the HF spark is removed once the welding current is established, but in AC mode the HF remains in place to stabilise the arc.

Lift Arc is a facility which allows for starting the arc without high frequency (HF). This is particularly useful in areas where HF could interfere with computer and tele-communications.

Pre-gas, on a variable timer, allows for purging the torch and weld start area prior to establishing the arc. This ensures the weld starts in an inert atmosphere.

Up-slope allows you to commence welding with a gradual (timed) increase in the welding current up to the selected main current level.

Down-slope is a gradual (timed) reduction in the welding current down to a final, normally pre-set level, thus eliminating crater cracks or high temperature gas holes on completion of the weld.

Post-gas, again on a variable timer, ensures gas coverage to protect the completed weld area from atmospheric contamination.

Trigger Latch (sometimes called 4T) save keeping the trigger pressed during the welding cycle, especially useful during long weld runs. An initial press and release of the trigger starts the weld and a subsequent press  and release stops the weld.

AC Balance (only on some AC DC TIGs) gives you the ability to offset the AC, in order to control the weld penetration, width and cleanliness.

Remote Control, normally achieved with a foot pedal, gives variable control of the welding current (and therefore arc). The pedal can also be used as the trigger switch.

Pulse simply pulses the frequency of the weld current to reduce heat allowing for easier welding of thin materials.
