PROBLEM
POSSIBLE CAUSE POSSIBLE SOLUTION
Low output or non-penetrating
weld.
Weld parameters too low. Adjust welding parameters
Too long or improper extension cord. Use a proper extension cord (#12 AWG
wire for 120V or #8 AWG for 230V
or heavier, no longer than 25 ft.). See
“Extension Cords”, page 11.
Poor ground connection or torch/electrode
connection.
Reposition clamp and check cable to
clamp connection.
Check connection of ground cable, torch
or electrode holder
Input power too low. Have a qualified electrician verify the
voltage at your outlet. If the voltage is
appropriate, verify that the circuit wiring
is sufficient for 10A in the case of 120V or
50A in the case of 230V.
Ground clamp, ground cable,
and/or welding cable get hot.
Bad ground or loose ground connection. Check connection of ground cable, torch
or electrode holder.
Check connection of the ground cable
to the ground clamp. Tighten cable
connection to ground clamp if needed.
Ensure the connection between the ground
clamp and workpiece is good and on
clean, bare (not painted or rusted) metal.
Frequent circuit breaker trips.
Machine is not the only piece of electrical
equipment on the circuit.
Make sure the welder is on a dedicated
circuit or is the only thing plugged on a
circuit.
Circuit breaker is incorrect/insufficient for
use with this machine.
Verify that the circuit breaker for the circuit
is a 10A time-delay (slow-blow) breaker
for 120V or 50A for 230V. If it is not,
have a qualified electrician install the
proper breakers.
Poor quality welds.
Insufficient gas at weld area. Check that the gas is not being blown
away by drafts and, if so, move to a more
sheltered weld area. If not, check gas
cylinder contents, gauge, regulator setting,
and operation of gas valve.
Rusty, painted, oily or greasy workpiece. Ensure workpiece is clean and dry.
Poor ground connection or torch/electrode
connection.
Check ground clamp/workpiece
connection and all connections to the
machine.
Difficult arc start.
Amperage is too low. Increase amperage setting.
Arc is wandering (TIG).
Tungsten is too large. Use a smaller tungsten.
