OUTPUT CURRENT CANNOT REACH RATED VALUE
Deviation of power voltage from the rated value will lead to unconformity of output current
value with the set value. When power voltage is lower than the rated value, maximum
output current of the welder may also be lower than the rated value.
TUNGSTEN TIP GETS BURNT TOO FAST
Reduce the heat of the tungsten tip by twisting knob 6 towards “-“.
TROUBLESHOOTING WELDING
PROBLEMS
RECOMMENDED ACTION
Weak Penetration
(For aluminum Tig welding)
Increase the welding heat, use 220VAC and use higher
output voltage
Twist knob 6 towards “-“ to transfer more heat to the
work piece
Weak Penetration
(For aluminum Tig welding)
Increase the welding heat, use 220VAC and use higher
output voltage
Tungsten Contaminated
Keep Tungsten 1/8 to ¼ inches from the base metal.
Re-sharpen the Tungsten if the tip is worn.
Poor Welding Appearance
The angle between the filler metal and the torch must be
less than 90 degrees.
Crater at the End of the Weld
Bead
Keep the torch on the base metal while the post flow
shielding gas flows to protect the metal and tungsten.
Reduce current with pedal and add more filler at the end
of the weld.
Weld Bead is Cracking
Reduce the heat more times between passes.
Preheat the base metal and reduce the filler wire size.
Material is Warping
Clamp the work piece tightly.
Add more tack welds until rigidity and stiffness is
developed.
To reduce heat by spreading the welding out around the
area. This can be done by using Stitch Welding techniques
and by alternating sides, taking your time, allowing the
pieces to cool between passes.
Melting Tungsten
Make sure there is no gas leaking, adjust the gas flow,
shift more negative on the knob 6.
Increase the Tungsten diameter. Increase the Post Flow.
For Tig welding, please use 100% pure argon.
Contamination in Weld Bead
Clean the base metal to make sure to remove any oil,
coating or debris.
Remove tungsten from torch and re-sharpen the tungsten.
