7. Press the wire into the grooves of the drive rolls by tightening the
clamp.
8. Remove the gas nozzle and unscrew the contact tip.
9. Turn on the device.
10. Unfold the handle so that it is in a straight line, then press
the button on the handle until the wire appears in the
outlet (approx. 20 mm), release the button.
11. Screw on the contact tip, install the gas nozzle.
12. Adjust the pressure force of the feed roller by turning
the pressure knob. Contact pressure too low, cause
drive roller will slip. Too high pressure force increases the feeding resistance
and deforms the wire, which may result in cutting it.
7.4 Connecting the shielding gas.
1. The cylinder with the appropriate shielding gas should be placed on the shelf of the semi-
automatic machine (if any) or against a wall and secure it against tipping over by securing it to the
bracket with a chain.
2. Remove the cap protecting it and unscrew the cylinder valve for a moment to
remove any contamination.
3. Install the regulator so that the gauges are in a vertical position.
4. Connect the semi-automatic machine with the cylinder (outlet from the reducer with the welding machine's stub)
with a suitable hose. The protective gas connection is located on the back of the device.
5. Unscrew the reducer valve only before welding. After welding is finished, the cylinder
valve should be closed.
6.
Avoid welding in an open space or in a draft - a blast of air can
disrupt the shielding gas stream and strip the liquid metal of its protection.
7.5 Selection of welding parameters for MIG / MAG
The basic parameters of the MIG / MAG welding process are: welding
current and electrode wire feed speed. Increasing the welding current causes an
increase in penetration (penetration depth) and elongation of the arc. Increasing
the wire feed speed causes the handle to be pushed upward from the workpieces.
This is because the welding current is too low. When the wire feed speed is too slow
or the welding current is too high, large droplets form at the end of the wire
electrode. Too large spattering indicates that the welding current is too low or the
electrode wire feed speed is too high. When welding in wall and ceiling positions,
the welding current can be reduced, while making filler welds, in order to obtain a
smooth face, the welding current can be increased.
