The length of arc is regulated by holding the tungsten electrode tip at a suitable distance
from work piece. A suitable arc length is usually about the diameter of the tungsten electrode.
When the arc is burning, move the electrode slowly forwards to the start of the weld, tilting
the torch to approximately 10–15° pulling angle. If necessary, adjust power source current
value so that a constant weld pool size is maintained for the forward travel speed. If necessary
to complete the weld, add compatible filler wire to the weld pool.
Stop welding by lifting the torch away from the work piece and by closing the gas valve on
the torch.
NOTE! Always secure the gas cylinder in an upright position with either a specially made wall rack
or cylinder trolley. Always close the cylinder valve after welding.

Using and fixing the shoulder strap
The machine is delivered with a fabric shoulder strap and metal clip set. The shoulder strap
can be used as a convenient and comfortable way to transport both the machine and cables
set. There are two identical metal clips. Fix one clip to each of the metal lifting eyes, located at
the top of the machine. Adjust the shoulder strap to a comfortable length. The machine can
now be carried.
Should you also wish to transport and secure the cables set, place the cable bundle over the
strap as shown, bring the strap and remaining free clip over the top of the cable bundle and
secure to the already fastened rear clip. As you take the weight of the machine with the strap,
the cable set is clamped securely into position ready for transport.
NOTE! The machine should not be used when hanging from the shoulder strap.
