To protect the weld pool from oxidation and impurities
during the welding process, a shielding gas flows over
and around the weld pool. This gas flow is provided by a
flux core within the welding wire electrode. The flux
melts due to the heat produced, giving off a gas. This gas
prevents oxygen, in the surrounding air, from coming
into contact with the molten pool at a critical time.
Solidification takes place, creating a much stronger,
cleaner weld, free of impurities.
BENEFITS OF NO-GAS MIG WELDING
1. No need for cumbersome or short life gas bottles
2. Better outdoor use as wind has less chance of
disturbing the gas shroud.
3. 50% faster welding time.
4. Operator training time kept to a minimum.
5. There is no slag removal, thus eliminating almost all
post-welding cleaning operations.
6. Minimum waste of welding consumables.
7. Overall, a faster more efficient way of getting the job
done.
8. Less heat - less distortion.
9. Ability to weld thin material.

9. Assembly & Installation
9.1 Fitting the welding screen
- Place the welding glass (A) over it in the frame for welding
screen(B).
- Insert the handle welding mask hole.
9.2 Fitting the wire spool
Wire types
Various welding wires are required for different applications. The
welding set can be used with welding wires with a diameter of 0.9
mm(For DJMMIG130) or 1.0mm(For DJMMIG195). The appropriate
feed rollers and contact tubes are supplied with the set. The feed
roller, contact tube and wire cross-section must always match each
other.
Wire spool capacity
Wire spools with a maximum weight of 0.45 kg can be fitted in the
welding set. (For DJMMIG130)
Wire spools with a maximum weight of 1 kg can be fitted in the
welding set. (For DJMMIG195)
9.3 Inserting the wire spool
- Unlock the housing cover by turning the fastening screw through
90
°
and flip open the cover.
- Check that the windings on the spool do not overlap so as to ensure
that the wire can be unwound evenly.
- Place the wire spool on the spool holder . Ensure that the end of the
welding wire is unwound on the side of the wire guide, see arrow.
