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

Description

Main On Off Swtich

Main switch on the welder, remember to turn off the welder as much as possible in-between setting up for welds

DC+ AC DC- selector

Do not change this setting with the main power switch ON.
This selector has three positions that control the mode of the welder

DC- (DCEN), DC Electrode Negative, used for Steel TIG
AC, used for Aluminium TIG
DC+ (DCEP), DC Electrode Positive, used for Arc

Working power range selector

Do not change this setting with the main power switch ON.
There are three possible working ranges, low, medium and high. Each has a slightly different range for DC or AC

Position	AC	DC
Up	140-310	125-310
Middle	40-165	40-190
Down	10-45	10-55

Percentage power dail

Main power control dial, used to fine tune the amp control of the welder.
This dial acts as a percentage of the current selected range.

Remote amp control enable

Used to enable remote amperage control when a foot control is installed.
Until we have a remote foot pedal this should be left in the OFF position.

High Frequency control

Controls the high frequency generation of the welder, this switch has three positions and each has a set use.

Up (IO) High frequency start, use this for DC TIG welding (Steels)
Middle (O) Off used for Stick welding
Down (I) On, used to AC Tig welding (Aluminum)

Remote trigger enable

This should be left in the ON position.
Used to enable the remote trigger, only place in OFF position when doing Arc welding

Gas overrun timer

Controls how long after arc cut off the gas will run for.
Outer scale is tungsten width, inner scale is time in seconds

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.
