8.1 Connect the earth cable quick connector
to the positive welding power output socket
(11). Connect the earth clamp to the work
piece. Contact with the work piece must
be firm contact with clean, bare metal, with
no corrosion, paint or scale at the contact
point.
8.2 Insert TIG torch power connection into the
negative welding power output socket (10).
Connect valve TIG torch gas line to the
regulator, ensuring all connections are tight.
8.3 Open gas cylinder valve and adjust regulator,
flow should be between 5-10 l/min depending
on application. Re-check regulator flow
pressure with torch valve open as static gas
flow setting may drop once gas is flowing.
8.4 Connect the machine to suitable mains power
using the mains input power lead (13) Switch
the mains power switch (14) to 'on' to power
up the machine. Set the welding mode switch
(7) to 'Lift TIG' .

Wire Jam Troubleshooting
• If wire jam occurs when the torch becomes hot, this is often because the heat causes the wire and the tip
to expand (which shrinks the hole in the tip). Using a slightly oversize tip can prevent this – eg: for 0.9mm
wire, use a 1.0mm tip.
• Do NOT over-tighten the drive roll tension – this will accelerate wear of the drive system, may distort the
wire & will cause further wire feed problems.
• Refer to page 15-16 for more troubleshooting tips.

8.5 Select the required output current using the
current control knob (5). You are now ready to
weld!
NOTE: The 160MST / 180MST is a DC (Direct Current)
output welder only, this means that it is unable to TIG
weld reactive metals such as Aluminium alloys and
Brass (which require AC output). DC TIG output is
suitable for steel, stainless steel and copper.
Tips & Tricks
Duty Cycle Rating
Welding duty cycle is the percentage of actual
welding time that can occur in a ten minute cycle.
E.g. 20% at 160 amps - this means the welder can
weld at 160 amps for 2 minutes and then the unit
will need to be rested for 8 minutes. All duty cycle
ratings are based on an ambient air temperature of
40°
with 50% humidity, which is the international
C
standard for such a rating. In an environment with
temperature s exceeding 40°
be less than stated. In ambient temperature less
than 40°
, duty cycle performance will be higher.
