NO. Trouble Solution Possible Cause
18 Arc will not start unless lift started. Check HF point gap. Clean and set to .035” Contact Tech-
nical Support for details. Make sure unit is set to HF
Points misadjusted, worn or dirty. HF not
selected
19 Tungsten is rapidly consumed. Check gas flow. Check for Leaks thoughout system/
regulator/tank. Check for 100% Argon. Use red thoriated or
any other type besides Green (Pure) or Zirconiated. Put torch
in Negative.
Inadequate gas flow. Too small of tung-
sten. Wrong shielding gas. Use only Ar.
Using green tungsten. Wrong polarity.
Possible contamination of shielding gas
from gas supplier.
20 Tungsten is contaminated, arc changes to a
green color.
Check and adjust stick out to minimum 1/8 inch. Tungsten is
melting. Reduce amperage or increase tungsten size. Re-
duce stick-out to less than 1/4”.
Tungsten is dipping into weld. Too long
of stick-out.
21 Porosity of the Weld. Discolored weld color.
Tungsten is discolored.
Increase flow rate on regulator. Check for kinks in tubing.
Increase post-flow time. Reduce stick-out to less than 1/4”.
Increase cup size, or use gas lens. Clean metal thoroughly
with approved metal cleaner, or use acetone and a rag to
clean metal
Low flow rate of shielding gas. High flow
rate of shielding gas. Tungsten stick-out
is too far. Too short of post flow period.
Wrong TIG cup size. Possible gas leaks
internally or externally due to loose
ttings. Base metal is contaminated with
dirt or grease.
22 Weld quality is poor. Weld is dirty/oxidized, or
porous.
Eliminate drafts. Move welder. Check if there is sufcient
shielding gas left in tank. Check gas flow. Adjust for higher
flow of gas. Listen for audible click of gas solenoid. If no
click is heard, then contact Everlast Support. Clean weld
properly. Increase pre flow or post flow.
Drafty conditions. Unit is located on the
workpiece and is blowing gas off due to
fan activity. Solenoid is sticking. Too
short of pre-flow or post-flow
23 Unstable Arc. Regrind to proper point. Wrong polarity. Place torch in DC
negative (-). Connect work clamp directly to item being weld-
ed.
Poorly ground or shaped tungsten. Bad
work clamp connection. Metal is indi-
rectly connected through table or other
item.
24 AC TIG will not weld properly Check and change immediately. Wrong connection of work or torch
