help with welding loop

I would teach regular command positions for your start, approach and weld start points and then use IMOV commands to incremental linear moves for your weld duration and your 20mm move. You will need to set these up in P variables.

What is your spacing?

I do it like this...

I typed from memory syntax may not be correct...

MOVJ VJ=100.00 Home

SETE P000 (2) 20 Sets Y to 20 mm
*LOOP
SFTON P001

MOVJ VJ=100.00 Approach
MOVJ VJ=100.00 At weld start
ARCON
MOVL P007 V=100.00 Move to weld end
ARCOF
MOVJ VJ=100.00 Depart

SFTOF

INC I001
ADD P001 P000 Adds Shift distance for next pass
JUMP *LOOP IF I001>5 Loops if less than 5 passes
SUB P001 P001 Clears shift amount
SUB P000 P000 Clears shift distance
SUB I001 I001 Clears pass counter

MOVJ VJ=100.00 Home

I edited to add SFTOF
