Be sure to

TIG
Welding
Tungsten
Inert Gas
welding
uses
a.gas
supply
to
create an
oxygen
free shroud around
the
weld area. A filler
rod,
inserted into a
tungstentip,
is used to. create
the weld
join.
1. Attach
the earth clamp
to
a
conductive
connected
part
of the weld-surface.
2.
Plug
in the unit to the mains
power
supply:(must
be
single phase)
and
then
switch on the
unit.
3. Set the switch to TIG
and set the
required
amperes,
based on the
thickness of the metal to
be
welded,
using
the
dial-on the
frontpanel.
For
HP-200PP
and-HP-250PP
models,
choose
the correct
pulse
function with the
switch.
4. Turn on
the
gas. supply.
5. Press the
trigger
on.the torch for
several seconds
until.all air is drained
from the
system:
6. Hold

electrode 2-4
mm from
the work
piece, press
the
trigger
and

you
can now

for several seconds. The
torch
should
be
kept

untilthe-arc is
extinguished.
MMA
Welding
Manual Metal Arc
welding
uses anelectrode
stick to
create.a contact
between the
material to be
welded. This is held in
place
with
the stick
clamp.
1..Attach the
earth-clamp
to a conductive connected
part
of the
weld surface.
2.
Plug.in
the unit to the mains
power
supply (must
be
single
phase)
and then
switch
on‘the
unit.
3. Set the
switch to MMA and set the
required amperes
using
the dial.on
the front
panel.
4.
You are now
ready
to
start.welding.
