Miller Dialarc HF
TIG (Tungsten Inert Gas) welding is particularly useful for aluminium, It uses an electrode nozzle with a fixed (should be permanent, but they do wear) tungsten tip where a plasma 'flame' is created (started with a high-voltage / high freequency starter) and used to heat the filler wire and joint. The nozzle allows a flow of inert shield gas around the working area, reducing slag creation and (particularly important with aluminium) oxidation.
The TIG welder is a 'stick' welder - the electrode / nozzle is held in one hand, and the filler wire applied with the other.
Shield gas
For the TIG we use a Pureshield Argon.
Capacity and rating
The Tig welder has a large range
Controls
Details on the front panel controls
Tungsten and collets
We have a selection of the following tungsten tips and collets to fit
Grinding tip shapes
Filler rods
We have the following stock of filler rods
- Steel
- Stainless steel
- Aluminium
- Copper
Power supply
A 63A plug and socket connection is used, with a pushbutton on/off control station and no-volt release.
RFID control of access will be installed shortly.
