JM-250P Basic Set-Up Guide – Standard (Synergic) MIG/MAG
For Standard (Synergic) MIG/MAG welding, set up as below and ensure you have
“Synergic” mode Selected. 2T/4T trigger modes can be selected dependant on
user requirements.
The parameter selection button (H) allows you to scroll through the adjustable
parameters for Standard Synergic MIG/MAG as follows:
- A. P-1: Gas pre-flow time (2T/4T)
- B. P-2: Initial parameters (4T only)
- C. P-3: Upslope time (4T only)
- D. – Peak welding parameters
- E. P-4: Downslope time (4T only)
- F. P-5: Final parameter (4T only)
- G. P-6: Post-flow time (2T/4T)
- H. – Parameter selection button
The corresponding indicators will be lit according to selected parameters, the variable setting is noted in the left display and the adjustable values are shown on the right displays which are adjusted using the right control dial.
Material Thickness Adjustment
In synergic mode “D. – Peak welding parameters” can be adjusted based on
material thickness, this is done by;
- Press and holding in the right hand dial until the display changes to material thickness (as above).
- You can then release the dial and select the thickness of material you are welding by rotating the same dial.
- To exit this mode simply press and hold the dial in again to revert back to the original display.
Please Note: The synergic settings are a guide only and dependent on your application adjustments may be required to achieve the desired welding characteristics.
Voltage Trim Adjustment
Trim adjustment should be set to 0.0 to start with and adjusted based on user
requirements, this is done by rotating the right hand dial when the machine is
not in material thickness selection;
- Adjusting the trim up from 0.0 to 30 will increase the heat input into the material and give you the effect of having less wire and a longer welding arc.
- Adjusting the trim down from 0.0 to –30 will reduce the heat input into the material and give you the effect of having more wire and a shorter welding arc.
