TIG series of welding machines can be configured to communicate exclusively with 

wireless foot pedal or remote control panel. This is done by a simple process of 

synchronising the wireless remote control and the machine frequencies. Each interface 

frequency assigned is unique, so it is possible to use several wireless control systems/ 

machines in the same area with no problems. The direct range of the wireless control 

system is approximately 100m, this will be affected by the physical location of the machine 

and the remote control.

Unstable Arc 

during welding 

Torch connected to DC + 

Connect the torch to the DC- output 

terminal 

Contaminated base metal 

Remove materials like paint, 

grease, oil, and dirt, including mill 

scale from base metal. 

Tungsten is contaminated 

Remove 10mm of contaminated 

tungsten and re grind the tungsten 

Arc length too long 

Lower torch so that the tungsten is 

off of the work piece 2 - 5mm 

HF present but no 

welding power

 

Incomplete welding circuit 

Check earth lead is connected. 

Check all cable connections. If 

using a water cooled torch check 

that the power cable is separated. 

HF present but no 

welding power 

No gas 

Check the gas is connected and 

cylinder valve open, check hoses, 

gas valve and torch are not 

restricted 

Set the gas flow between 10 - 15 

l/min 

Tungsten melting into the 

weld pool 

Check that correct type of tungsten 

is being used. Too much current for 

the tungsten size so reduce the 

amps or change to a larger tungsten 

Arc wanders 

during welding 

Poor gas flow 

Check and set the gas flow between 

10 - 15 l/min flow rate 

Incorrect arc length 

Lower torch so that the tungsten is 

off of the work piece 2 - 5mm 

Tungsten incorrect or in poor 

condition 

Check that correct type of tungsten 

is being used. Remove 10mm from 

the weld end of the tungsten and re 

sharpen the tungsten 

Poorly prepared tungsten 

Grind marks should run lengthwise 

with tungsten, not circular. Use 

proper grinding method and wheel. 

Contaminated base metal or 

filler wire 

Remove contaminating materials 

like paint, grease, oil, and dirt, 

including mill scale from base 

metal. Remove all grease, oil, or 

moisture from filler metal 

Incorrect filler wire 

Check the filler wire and change if 

necessary 

Arc difficult to 

start or will not 

start welding 

Incorrect machine set up 

Check machine set up is correct 

No gas, incorrect gas flow 

Check the gas is connected and 

cylinder valve open, check hoses, 

gas valve and torch are not 

restricted. Set the gas flow between 

10 - 15 l/min flow rate 

Incorrect tungsten size or 

type 

Check and change the size and or 

the tungsten if required 

Tungsten is contaminated 

Remove 10mm of contaminated 

tungsten and regrind the tungsten 

Loose connection 

Check all connectors and tighten 

Earth clamp not connected to 

work 

Connect the earth clamp directly to 

the work piece wherever possible 

Loss of high frequency 

Check torch and cables for cracked 

insulation or bad connections.
