8. TROUBLE SHOOTING
MMA Stick welding problems
• Stick electrode „blasts off‟ when arc is struck
Welding current set to high, reduce amperage
or use thicker electrode Contaminated electrodes or material
•
Electrode sticks in weld puddle Welding current is set too low Arc is too short, keep electrode
further away from work
•
Excessive splatter Too long an arc, keep electrode closer to work
•
Poor penetration Travel speed too fast Too much welding current, reduce welding amperage
•
Porosity in weld Electrodes are damp Arc too long, get electrode closer to work

Tig welding problems
•
No output - Power light is not lit
Check machine on/off switch is in the ‗on‘ position Check
Input power to machine Check plug wiring Check mains trip / fuses
•
No output - Fan runs - Power light is lit Check torch connections are secure and torch switch
operation, try replacing tig torch. If you have a multi-meter check continuity between pins 1 and 2
on torch switch plug when pressing torch switch
•
No output - Power light is lit - Warning light is lit Welding application may have exceeded
recommended duty cycle, allow machine to cool down until the warning light goes out.
•
No output
–
Power light is lit
–
Gas at torch end when trigger pressed Check torch condition
–
possible break in torch power cable
–
replace torch
•
Machine keeps overheating - Warning light is lit on machine Check if fan is running
–
if not
contact R-Tech for repair Check the cooling vents for obstruction, blow out machine with clean
dry low pressure air supply. Check for adequate ventilation around machine
