Description

possible Cause

Remedy

Welding arc 

cannot be 

established

(a) Work clamp is not 

connected to the work 

piece or the work/torch 

leads are not connected 

to the machine
(b) Torch lead is discon-

nected

(c) Gas flow incorrectly 

set, cylinder empty or 

the torch valve is off

a) Connect the work 

clamp to the work 

piece or connect 

the work/torch leads 

to the right welding 

terminals.
(b) Connect it to the 

‘.’ terminal.
(c) Select the right 

flow rate, change 

cylinders or turn 

torch valve on.

Arc start is not 

smooth

(a) Tungsten electrode is 

too large for the welding 

current .
(b) The wrong electrode 

is being used for the 

welding job.

(c) Gas flow rate is too 

high.
(d) Incorrect shielding 

gas is being used.
(e) Poor work clamp 

connection to work piece

(a) Select the right 

size electrode
(b) Select the right 

electrode type.  

Refer to basic TIG 

welding guide
(c) Select the correct 

rate for the welding 

job. Refer to basic 

TIG welding guide
(d) Select the right 

shielding gas. Refer 

to basic TIG welding 

guide
(e) Improve 

connection to work 

piece

Description

Possible cause

Remedy

The welding 

arc cannot be 

established

(a) The primary supply 

voltage has not been 

switched on
(b) The welding power 

source switch is switched 

off
(c) The power source is 

latched on 
(d) Loose connections 

internally

(a) Switch on the 

primary supply 

voltage
(b) Switch on the 

welding power 

source.
(c) Switch the power 

source on and off
(d) Have a 

qualified service 

engineer repair the 

connection

Maximum 

output welding 

current cannot 

be achieved 

with nominal 

mains supply 

voltage

Defective control circuit

Have a qualified 

service engineer 

inspect then repair 

the welder

Welding 

current 

reduces when 

welding

Poor work lead 

connection to the work 

piece

Ensure that the 

work lead has a 

reliable electrical 

connection to the 

work piece

A total loss of 

power, pilot 

lamp is off, 

no output, 

the fan is not 

operating

(a) Failure of input 

voltage
(b) Possible over voltage
(c) Internal fault with the 

machine

(a) Re-establish 

mains supply
(b) Check voltage 

and if necessary 

move machine to 

alternative supply

(c) Have a qualified 

service engineer 

inspect then repair 

the welder

Fault lamp is 

on, no power 

output

(a) Machine overheated
(b) Over current state
(c) Internal fault with 

machine

(a) Allow to cool 

with fan running
(b) Switch off 

mains power to the 

machine and re start

(c) Have a qualified 

service engineer 

inspect
then repair the 

welder

 

rOutIne MaIntenanCe

The only routine maintenance required for the power supply is a 

thorough cleaning and inspection, with the frequency depending on 

the usage and the operating environment.

Warning 
Disconnect primary power at the source before removing the cover. 

Wait at least two minutes before opening the cover to allow the 

primary capacitors to discharge.

To clean the unit, remove the screws securing the outer cover, 

lift off the outer cover and use a vacuum cleaner to remove any 

accumulated dirt and dust. The unit should also be wiped clean, 

if necessary; with solvents that are recommended for cleaning 

electrical apparatus.
