9.
Now reconnect the welding machine with the mains and switch the power switch on again. Ad-
just the feed speed desired.
10.
Do point the gun away from your body or other persons and press the trigger to begin feeding.
Note!
While doing so, observer the drive roll to see if there is a slip between the roll and wire. If
there is one, switch the machine off and tighten the pressure regulator
(1).
Then re-check.
11.
As soon as the wire comes out of the gun, re-place the contact tip and nozzle. Cut off approx.
0.5–1
cm wire in front of the contact tip.
Attention!
Do not point the welding gun towards your own body or towards other persons while the wire is being
inserted or coming out; never hold the hand in front of the contact tip; the cut-off end of the wire is
extremely sharp! Neither hold your fingers near the feed rolls; they risk to be pinched between them.
Use
Using this welding machine, you will be able to perform many different welding applications; however,
these must be trained and tested before you can embark on a real project. The welding process de-
scribed in the following is to be considered as base for beginners.
1.
Always wear a welding helmet, gloves, a long-armed shirt, and long-legged trousers when weld-
ing.
2.
Connect the earth clamp to the pieces that you will be welding. Make sure that the contact point
of the earth clamp is a clean piece of metal free from paint, grease, rust, oil, etc. It is advisable
to connect the earth clamp as close to the welding area as possible.
3.
Check the welding area making sure that it is free from paint, grease, rust, oil, etc., too.
4.
Connect the welding machine to the power supply and switch on the power switch.
5.
Press the trigger of the welding gun. The gun must point away from your body. Then disengage
the trigger and cut off approx. 0.6
cm (¼″) wire.
6.
Introduce the wire end protruding from the gun into the spot to be welded.
7.
Hold the welding gun perpendicularly to the material base and tilted back by 15–20°.
8.
As soon as you engage the trigger and the arc has been ignited, you will see a puddle form,
that consists of welded material; this puddle, called the welding bead, follows the movements
of the welding gun. The size of this puddle determines the speed that you should apply when
moving the welding gun.
9.
Disengage the trigger of the welding gun to interrupt the welding process.
10.
After welding, switch off the device and disconnect it from the power supply.
