Welding Tips

Travel Speed

There are a range of welding movements used in welding. 

Generally some form of zig-zag motion is used to ensure the arc 

acts against both sheets to be welded. 

The torch should be moved along at a smooth speed that will 

give the size of run required. At the same time, the wire is fed 

downwards to keep the correct welding distance at all times. 

Excessive travel speeds lead to poor fusion and lack of penetration. 

While too slow a rate of travel may damage the work piece and 

can lead to burning a hole through the material.

Electricity

The electricity flows through the wire and will not leave the wire 

unless it is near an earthed object. Electricity always finds the 

fastest path to the earth. When the earth cable  clamp is connected 

to the metal work piece a direct earth connection is created back 

to the welder. When the wire touches or is near the earthed work 

piece when the trigger is squeezed, electricity flows through 

the wire, the metal work piece and then through the earth cable 

straight back to the welder.

7. TROUBLESHOOTING

Symptom

Possible 

Cause

Suggested Solution

No Power

On/off 

switch is off Check on/off switch is in the on position.
Power 

supply fault

Test power supply with another product, 

avoid using extension leads.

Circuit 

breaker 

tripped

Check the rating of the circuit breaker 

on the supply and other appliances 

connected to the circuit. 

The welder is a high power device and 

it is recommended that it is the only 

appliance on the circuit to ensure it has 

enough power to operate.

Difficulty 

starting arc

Inadequate 

earth clamp 

connection

Check earth clamp has good connection 

to material being welded. Surface for 

clamp connections needs to be bare 

metal, remove rust or paint.

Welding 

technique

Hold torch at correct angle, practice on 

scrap material.

Welder cuts 

out

Thermal 

overload 

active

The thermal overload light will light up 

and the welder will not operate until 

cooled down and the light goes out. This 

is normal in heavy welding, allow the unit 

to cool down.

Sticking wire

Incorrect 

settings

Increase voltage & wire feed speed to 

recommended setting.

Coated 

work piece

Clean weld area to bare metal.

Incorrect 

wire type/

size

Check that the wire type and size is 

appropriate for the material being welded.

Excessive 

welding wire 

consumption

Welding 

voltage too 

high

Reduce voltage.

Wire size 

too small for 

material

Change to larger wire size.

WARNING! 

THE WELDER SHOULD ONLY BE SERVICED 

BY QUALIFIED PERSONNEL.
