Ordering Numbers - Kemppi 25 Operating Manual

• Pressure cumulated in long gas hoses will cause a burst of shielding gas
• Flow of shielding gas is too low or too high (causes turbulence). In short
• Distance between the gun and the work piece is too long. In short arc
• Angle of tilt of the gun is too large.
• There is too much draught at the welding location.

at the beginning of welding, which may cause turbulence or mixing of
air into the shielding gas. The reason for this might also be a faulty or a
poorly adjusted relief valve, which puts too much pressure into the gas
hoses.
arc range a flow of 8 – 15 l/min, in hot arc range 10 – 20 l/min is to be
used.
welding, keep the gas nozzle at a distance of 10 – 15 mm and in hot arc
welding at a distance of 15 – 30 mm from the work piece.
