●
Weak HF - Poor arc striking - welding output normal
1 Check torch and earth connections - is torch cable insulation in good condition.
2 Check for leaks or contamination on gas hoses & connections.
3 Gas flow may be insufficient, increase gas flow, reduce tungsten stick out from ceramic
4 Keep output cables short as possible
●
HF spark is present at the tungsten electrode but unable to start welding arc, Machine has
normal welding output
1 Tungsten may be contaminated -replace or sharpen
2 The current may be set too low
3 Tungsten may be to large for process
4 Gas flow may be insufficient, increase gas flow, reduce tungsten stick out from ceramic
●
No HF when torch trigger pressed, no blue spark between HF points
Examine and clean HF points with clean dry low pressure air line
HF PCB faulty - Contact R-Tech for repair
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
